False Alarm from Indian Tsunami Early Warning Centre

Thursday morning I noticed a worrying message from the Indian Tsunami Early Warning Centre:
Date: Thu, 21 Jun 2018 03:29:03 +0530 ...
"IOTWMS-TSP INDIA has detected an earthquake with the following preliminary information:
Magnitude  : 8.5  M
Depth      : 10  km                      
Date       : 20 JUN 2018
Origin Time: 2154UTC
... this earthquake may be capable of generating a tsunami affecting the Indian Ocean region."
This was alarming because an 8.5 magnitude earthquake is extremely large. But then I noticed the location was given as "TEST_TEST_CENTRAL CHILE".

As confirmed later, this was a test message which escaped from the internal system, out to the public:
"CANCELLATION MESSAGE ...
Date: Thu, 21 Jun 2018 05:33:31 +0530

IOTWMS TSUNAMI SERVICE PROVIDER INDIA (ITEWC)
This is not a real event. This event was issued due to an operator error during an internal test. ..."
It took two hours to issue the correction, which is an unacceptably long time.

U.S. Tsunami Warning System Problem

Tsunami Warning after an earthquake
near Alaska at 01-23-2018 09:35:57 UTC
The U.S. Tsunami Warning System issued a warning after an earthquake near Alaska at 01-23-2018 09:35:57 UTC.

However, when I checked the home page at 11:15 UTC the map did not show the earthquake location and instead said "Earthquake Layer failed to load" and "Alerts/Threats Layer failed to load". This would appear to be because the system was overloaded. I then canceled the page request, not wishing to make the situation worse.

The NWS Tsunami Alerts Twitter feed was working at the time. However, the twitter alerts contained a link to the same non-functioning web page:

    TSUNAMI WARNING 4: See http://tsunami.gov  for alert areas.
    M7.9 175mi SE Kodiak City, Alaska 0032AKST Jan 23:
There were some maps provided direct in the twitter feed, which did display:

However, these maps are difficult to interpret, as they showed a series of predicted arrival times as colored lines, with no scale as to the size of the wave. The waves were shown reaching Australia in 11 hours, although no warning had been issued by the Joint Australian Tsunami Warning Centre. 

Colored dots on the map indicated the location of tidal gauges and "DART". Not explained on the map, DART is a system of "Deep-ocean Assessment and Reporting of Tsunamis" detectors. 

Fortunately in this case the tsunami was only 6 inches high (as reported at Old Harbor Alaska 0256  PST Jan 23). However, I suggest revising the design to use simple static map images on the web site, using a few colors, so the file is small. Also the use of extensive JavaScript should be avoided to allow the page to load quickly. At present the HTML file is only 61 kBytes, but the other files are 3.4 Mbytes, including a 1.2 Mbyte JavaScript file.

The tidal gauge and DART locations are not of use to someone who wants to know when, when and how large a tsunami to expect. These should be omitted from the map, unless they show a reading. The predicted arrival time should be limited to a few hours, until the existence of a significantly sized tsunami is confirmed.

Indonesian Tsunami Early Warning System Issuing False Alarms

The Indonesia METEOROLOGICAL CLIMATOLOGICAL AND GEOPHYSICAL AGENCY (BMKG) has started issuing warnings online from the Indonesian Tsunami Early Warning System (InaTEWS). Unfortunately, InaTEWS is relaying bulletins issued from other regional warning systems. These bulletins are already relayed by UNESCO, so that multiple copies of irrelevant Tsunami warnings are received. As an example InaTEWS issued a bulletin about an earthquake near Nicaragua on 24 Oct 2012 at 0045 UTC. It would be a very long time, if ever, before this effected Indonesia, on the other side of the Pacific Ocean.

Indian Ocean Wide Tsunami Watch

Map of Magnitude 8.7 earthquake off the western coast of Northern Sumatra (Indonesia) at 08:39 UTC 11 April 2012The Pacific Tsunami Warning Center in Hawaii issued a Indian Ocean Wide Tsunami Watch at 08:45 UTC on 11 April 2012. This followed a Magnitude 8.7 earthquake off the western coast of Northern Sumatra (Indonesia) at 08:39 UTC. The latest bulletin, number 4 at 10:54 UTC, reported a tsunami wave of 1.06 m at Meulaboh, capital of West Aceh, Indonesia. A magnitude 8.3 aftershock was also reported. The Joint Australian Tsunami Warning Centre has not issued any warning for Australia.

Tsunami Test Message Failure

The Pacific Tsunami Warning Centre in Hawaii issued an unscheduled test message for the Caribbean Sea and Adjacent Regions Tsunami Warning System (CARIBE-EWS) at 16:40:36 UTC 4 February 2012. It appears to have taken just under four minutes to get to me by email at 11:44:20 UTC. This indicates a failure of the system as the message took more than a few minutes to arrive. Most of the delay in the initial step from the PTWC to UNESCO.

A potential problem remains with the formatting of the tsunami warnings, in that they may be mistaken for Spam. Here is the spam report for this message:

CARIBE WAVE 11/ LANTEX 11 tsunami exercise

Tsunami exercise CARIBE WAVE 11/ LANTEX 11 is being conducted. A exercise Caribbean-Wide Tsunami Watch Message was issued at 1302Z 23 MAR 2011. This was relayed by the West Coast/Alaska and NWS Pacific Warning Centres. The messages received have spam warnings due to there being no sender's name and all upper case in the body of the message. This is not sufficient to prevent reception of the messages, but is a potential problem which needs to be addressed.
The CARIBE WAVE 11/ LANTEX 11 tsunami exercise is being conducted to assist tsunami preparedness efforts throughout the Caribbean region. Recent events, such as the 2004 Indian Ocean, 2009 Samoa, and 2010 Haiti and Chile earthquakes and tsunamis, attest to the importance of proper planning for tsunami response. The purpose of the exercise is to improve Tsunami Warning System effectiveness along the Caribbean coasts. The exercise provides an opportunity for emergency management organizations throughout the Caribbean to exercise their operational lines of communications, review their tsunami response procedures, and promote tsunami preparedness. Regular exercising of response plans is critical to maintain readiness for an emergency. This is particularly true for tsunamis, which are infrequent but high impact events. Every Caribbean emergency management organization (EMO) is encouraged to participate.

Japanese Earthquake and Tsunami

The Pacific Tsunami Warning Centre issued Bulletin number 1 for a Tsunami Watch at 0555 UTC 11 March 2011 for Japan much of the western and mid pacific are nearby areas. This was due to an earthquake at 0546Z 11 MAR 2011 near the east coast of the Japanese island of Honshu, Japan, then assessed at magnitude 7.9. This was expanded with bulletin 2 at 0643Z, with the magnitude of the earthquake reassessed as 8.8. At 0730Z bulletin 3 upgraded this to a widespread warning with gauge reports of up to 2.79m at HOKKAIDO. Up to now the latest bulletin is number 7, warning of possible damage along coastlines of all islands of Hawaii.

The Indian Ocean Tsunami Warning System relayed the initial bulletin at 05:56:02 GMT. The PTWC web site is responding to web page requests with no significant delays. For an overview of how these systems work, see my talk to the East Mediterranean Tsunami Warning Centre in Istanbul.

Policy lessons to reduce disaster risks

Greetings from the new Crawford Building, at the Australian National University in Canberra, where Peter McCawley is speaking on "Preparing for megadisasters: Lessons from the Asian tsunami". Peter is a Visiting Fellow in the Arndt-Corden Division of Economics at the ANU working on policy for reducing disaster risks faced by the poor in developing countries. He is finishing a book on disaster preparedness.

Teach disaster reduction techniques

Below I have made some quick notes on Peters talk. The most significant point for me was "How do we make agencies learn?". That is, there are many detailed analysis's of what happened in previous disasters and lists of recommendations for change. But the national and international agencies involved do not appear to learn these lessons. The answer to this seems obvious to me: to make the organisation learn you teach the individual staff.

Last Saturday, the Australian Prime Minister announced that ANU would be providing training for the Australian Public Service. The ANU could therefore formally and officially teach disaster prevention to the Australian Public Service. Most of this training will be done online and therefore this training could also be made available to staff of national and international agencies. This training could incorporate open source software which would then be available for coordination of international operations.

I asked Peter about this and he commented that the problem was sustaining the effort: many of the post tsunami web sites are now moribund. I commented that the Sahana Foundation was set up to provide long term support for disaster software and proved itself in several situations (winning humanitarian awards). Perhaps this could be expanded to cover education as well. This could use the integrated education techniques I discussed with Last week Cameron Shorter a few weeks ago.

One of the audience recommended UNOGunog Humanitarian Reform and another (from AusAid) recommended the Global Disaster Alert and Coordination System: Virtual OSOCC.

Notes from the talk

Peter cited "A ripple in development? Long term perspectives on the response to the Indian Ocean tsunami 2004" from the Swedish International Development Cooperation Agency (Sida), 29 May 2009. He used this to help argue that the international aid response to the Indian Ocean Tsunami was large aid project, but not significant in the long term.

Peter criticised the Australian Government for not placing an emphasis on human security in the region. Instead the emphasis as on military security for nation states, not people.

He showed a reproduction of the "Great Wave off Kanagawa" and pointed out it is not a Tsunami.

Peter commented that the Asian tsunami had high levels of aid provided, compared to the Burma cyclone, due to political limitations.

Peter showed a graph of the economic stages of a disaster. There is sudden economic loss due to the disaster. Initial relief is local, followed by international relief. Rehabilitation follows, then high levels of economic activity during reconstruction, the a drop off in activity afterwards.

Livelihood programs are needed, but Peter comments that donor agencies have difficulty with these on a small scale and quickly. Rebuilding infrastructure is important, but can take years to organise, as it involves rebuilding roads, bridges, airports. Donors like to build large infrastructure projects but these do not provide rapid aid to the local economy.

Social capital may be lost if new housing is not design to suit local social structures. As an example emergency housing designed for a small nuclear family will not work for an extended family.

Peter commented that coordination is a major challenge following a disaster. Indonesia did well setting up a strong agency with a cabinet level minister in charge. The flow of finance can also be complex.

It occurs to me that these could be a role for the Sahana foundation, to produce software to help with coordination. This would only be in part about producing software, what would be more important would be to produce some de-facto standardisation of the paperwork required by different agencies.

One problem is looking after assets provided by aid. The local administrators now have the problem to manage these Peter commented that Indonesia has now a large stock of physical assets. There is no inventory of what has been provided, and funds for maintenance have not been given.

Peter argued that disaster risk reduction and preparedness needed to be carried out in advance of a disaster, rather than responding afterwards. He listed 8 lessons:
  1. Objectives: Delivery of aid is only one objective of those involved.
  2. Local responses: The fastest relief for the tsunami was provided by the local community, with little recognition/
  3. Coordination: International coordination is needed.
  4. Stages: Different: agencies respond at different phases
  5. Supply oriented donors: Donors tend to supply, not ask what is actually needed
  6. Finance: Problematic (I did not understand this point)
  7. Cost increases: Aid response may cause local cost increases
  8. Methods of spending: Cash or kind.

Poor people in developing countries live risky lives. Amongst the risks they face are the risks of disasters. In recent years – and especially following the 2004 Asian tsunami – the international community has been paying increasing attention to the impact of disasters in developing countries. This new approach, in turn, is part of a heightened awareness of the need to strengthen human security for the poor in developing countries. This seminar will consider both the international and regional response following the 2004 Asian tsunami. Some policy lessons to be learnt in aiming to reduce disaster risks faced by the poor in developing countries will be outlined.

Peter McCawley is a Visiting Fellow at the ANU in Canberra . Between 1980-85 he was Head of the Indonesia Project. Most recently, he was Dean of the Asian Development Bank Institute based in Tokyo in 2003-2007. One of his main areas of current research is the provision of aid following the 2004 tsunami in Asia . In cooperation with Professor Sisira Jayasuriya from LaTrobe University he has recently completed a book on the Asian tsunami to be published later this year.

Atlantic and Pacific Tsunami exercises under way

Tsunami exercise "LANTEX 10" commenced at midnight GMT today, with the first message sent by the West Coast/Alaska Tsunami Warning Centre. This is a scripted exercise to test tsunami response plans. LANTEX 10, simulates a magnitude 7.5 earthquake off the New England coast. Detail of the exercise, including the timeline of what is scheduled to happen when is available in the LANTEX10 Handbook Version 3.0.

There is also the corresponding Pacific exercise PACIFEX 10, simulating a magnitude 9.0 earthquake south of the Alaska Peninsula. Details are in the PACIFEX10 Handbook Version 3.0. In addition Alaska and California are conducting tests of their Emergency Alert Systems, including on TV and radio the same day.

It should be noted for those used to more free flowing exercises, as used by the UK and Australia, the US exercises tend to be more tightly scripted.

ps: Also note, as it says in all messages issued: THIS IS ONLY AN EXERCISE.

Australian Tsunami Awareness Review

Yesterday, the Attorney-General, Robert McClelland, announced a Tsunami Awareness Project, and a review of the public response to tsunami warnings. These are of limited value due to a lack of detail about the review and restrictions placed on distribution of the awareness campaign materials by the Attorney.

"Tsunami Education and Awareness" is a CD-ROM and web site distributed by Surf Life Saving Australia. The Attorney says he has written to Emergency Services Ministers and Surf Life Saving Organisations requesting a review of the public response to tsunami warnings. It is not clear who is conducting the review, what resources have been made available for it or when it is to be completed. The Attorney did not release the proposed terms of reference for the review.

While Australia has a well designed and run Joint Australian Tsunami Warning Centre (JATWC) provided by the Bureau of Meteorology and Geoscience Australia, there is no national system for the warnings to be distributed through government agencies, nor a response coordinated. Warnings are sent to an ad-hoc arrangement of state organisations and then to an assortment of local bodies. It is not surprising that the public may take little notice of the resulting confusing and contradictory messages they get as a result.

An example of the lack of effort for Tsunami warning is show by the Queensland Government's "Queensland Tsunami Notification Protocol" (Version 1 , 9 December 2009). This has been distributed as a 9 page 3.7Mbyte PDF document, scanned from a paper original. As a result the text of the protocol cannot be found with a search or copied for use. The protocol contains such outdated procedures as the JTWC contacting Queensland by telephone before issuing a Tsunami warning. This is not an acceptable procedure as it would delay the issue of a warning and risk public safety. The protocol assumes a 90 minute warning for a Tsunami. However, situations can arise much more quickly, which would place emergency personnel in the ethical dilemma of either following procedures or ignoring them to issue a timely warning. The Protocol does not specify how agencies within Queensland are notified. Based on previously experience of a Tsunami warning in Queensland, it is not clear the Queensland Government has a system for coordinating a response.
The review will be conducted with State and Territory Emergency Services Agencies, Local Governments, surf life saving organisations and other stakeholders and will focus on:
  • ways to better educate and prepare the public for, and improve its response to, future tsunami warnings, and
  • mechanisms for the effective distribution of tsunami warnings to the public. ...
From: Tsunami Awareness Project, Media Release, Attorney-General, Robert McClelland, 6 March 2010
Tsunami Education and Awareness Material

The distribution of the awareness material distributed by Surf Life Saving Australia will be greatly hampered be the Attorney's decision to ban making copies. The Attorney has imposed copyright restrictions on the material banning the making of any copies without written permission of the federal government. The Attorney could have instead used a Creative Commons licence, freely allowing not-for-profit distribution.

Tests on the main menu page of the awareness kit show:
  1. No HTML Validation Errors.
  2. Score of only 35/100 with the W3C mobileOK Checker. It would be very useful for such a awareness program to be compatible with mobile phones used by young people.
  3. On an automated accessibility test (TAW 3.0 for WACG 1.0) the page had zero Priority 1, sixteen Priority 2 and 4 Priority 3 problems. It would be useful if the page at least met current Australian guidelines for accessibility of web sites by the disabled.

Australian Tsunami Warning Issued after Chile Earthquake

Australian Tsunami Warning MapThe Joint Australian Tsunami Warning Centre (JATWS) issued a National Warning Summary and Marine Tsunami Warnings for Norfolk Island, Lord Howe Island, Tasmania, Victoria, New South Wales and Queensland at 5:37AM after an earthquake in Chile. The marine warning was for dangerous waves, strong ocean currents and some localised flooding from around 8am (times vary by location).

The text of the warnings issued by the JATWS are confusing, as they say "TOP PRIORITY FOR IMMEDIATE AND FREQUENT BROADCAST", but do not order use of the Standard Emergency Warning Signal (SEWS).

The Pacific Tsunami Warning Centre issued an Expanding Regional Warning for areas near the earthquake at0646Z 27 FEB 2010. It issued a Pacific Ocean-wide Warning at 1045Z 27 FEB 2010, with supplements every few minutes.

WCATWC Traffic Light Tsunami IndicatorThe West Coast and Alaska Tsunami Warning Centre (WCATWC) turned their traffic light symbol to orange to indicate an advisory.

WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE
APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL
CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND
SEVERITY OF THE THREAT.

A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE
LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY
SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM
ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND
THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT.
THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE.

Tsunami Recovery in Sri Lanka

Cover of People's Verdict on Tsunami Recovery in Sri Lanka by Muttukrishna SarvananthanThe People's Verdict on Tsunami Recovery in Sri Lanka by Muttukrishna Sarvananthan (International Centre for Ethnic Studies, Colombo, 2007, ISBN: 978-955-580-114-0) provides an useful analysis of the recovery operations after the 2004 Indian Ocean Tsunami. The emotive title of "people's verdict" is unfortunate, as it may make the reader think this is some sort of left wing political propaganda, rather than the careful empirical research it is. The book is based on an extensive survey of tsunami survivors and provides useful lessons for future disaster recovery operations,. Unfortunately even so long after the events of 2004 it also notes where the recovery operation is still lacking, particularly with housing and schooling. Some surprising findings were that there was little corruption or discrimination in the distribution of aid. The provision of employment and schooling were identified as important issues. I acme across this book by accident in the new arrivals at the Australian National University Library. The International Centre for Ethnic Studies might wish to consider distributing excepts from this book online for free, so as to make the information more widely available.

Tsunami warning and response for Samoa

The Pacific Tsunami Warning Centre detected a magnitude 7.9 earthquake in the Samoa Islands region at 1748Z 29 September 2009. In response a Tsunami Warning and Watch was issued 16 minutes later at 1804Z (Bulletin 1). In all 11 messages were issued, the last being 0501Z 30 September 2009. The centre issued messages for both Hawaii and the Pacific.

Due to the closeness of the earthquake to Samoa and limitations in the technology available, the warning message was issued 5 minutes after the predicted arrival time of the Tsunami (1759Z) at the first population centre, Pago Pago in American Samoa.

The centre issues warnings to national authorities and there is then a delay while local authorities decide if, and how, to warn the public.
At best only 11 minutes warning could have been provided (assuming instantaneous detection, analysis and alert). Telecommunications systems can provide a warning within one minute.

The warning was also forwarded by email by UNESCO to the Interim Indian Ocean warning system mailing list. This message was dated Tue, 29 Sep 2009 18:04:43 GMT. It was received from UNESCO approximately three minutes later by the Fastmail.fm mail system and a summary by SMS via Vodafone Australia within one minute.

Samoa uses a system of sirens and church bells to the warn the population of Tsunami. The USA has a system of "NOAA Weather Radio" which issues automated warnings. There is a NOAA transmitter in American Samoa, located in Pago Pago.

During a visit to Samoa in 2005 to teach web design for UNESCO, I noticed that while a national digital telephone network had not yet been installed, there was a limited private GSM service (a similar service existed in Tonga). There were proposals for a GSM network in Samoa in 2007, but it is not clear how this has progressed. The significance of these networks is that they provide the SMS and SMS cell broadcast networks, which could be used to issue emergency warnings.

Indian Ocean Tsunami Warning Cancelled

The Pacific Tsunami Warning Center (PTWC) issued a warning for the Indian Ocean at 2005 UTC (bulletin number 1). This followed a 7.7 earthquake near the Andaman Islands. A tsunami was predicted to arrive in towns in the islands within 15 minutes, and on the Indian mainland including KAKINADA within an hour, and later: MYANMAR, INDONESIA, THAILAND, BANGLADESH. The JAPAN METEOROLOGICAL AGENCY (JMA) issued a similar bulletin at 2025. The PTWC issued a second bulletin at 2105Z saying a tsunami was generated, but a third bulletin at 2124Z corrected this saying no tsunami had been observed. At 2211Z PTWC cancelled the Tsunami watch. A problem with this process is the difference in times and details between the Japanese and US warnings. The JMA seems to issue fewer, later and less detailed bulletins.

Australian Tsunami Warning Issued

The Joint Australian Tsunami Warning Centre issued a Land Warning for Lord Howe Island at 10:45 PM EST on 15 July 2009 and a Marine Warning for much of south east Australia. This followed an earthquake off the south of New Zealand at 0923Z 15 JUL 2009. The media were requested to use the Standard Emergency Warning Signal (SEWS) for Lord Howe Island, but not mainland Australia.

At 12:14 AM EST on Thursday 16 July 2009 threat for Lord Howe Island was downgraded to a Marine Warning and use of the SEWS cancelled. One anomaly with this was that the message for Lord Howe Island (IDY68035) used different text to those for the mainland (IDY68028). The mainland messages said "Marine Warning", whereas the Lord Howe Island message did not contain that phrase. This may seem a minor point, but a lack of use of standard wording can cause dangerous misunderstandings.

Unlike the Pacific Tsunami Warning Center, the Australian Centre does not appear to provide a public archive of issued messages, so I have included two in this posting for research purposes.

For a discussion of warning systems see my "National Bushfire Warning System", Seminar, College of Engineering and Computer Science, ANU, Canberra, 16 April 2009.

Fault in Pacific Tsunami Warning System

The Pacific Tsunami Warning Center (PTWC) issued a warning 19 March 2009 after a magnitude 7.7 earthquake near Tonga. A small tsunami of 0.04 m was later reported and in all six messages were issued, before the warning was cancelled. While the text based warning messages worked as planned (I received trimmed versions by mobile phone SMS as well), there appear to be continuing problems with the HTML versions on the NOAA web site. The PTWC needs to review its web design to ensure poor formatting is not impeding this important service.

When I attempted to access the PTWC web site at 8:10am this morning the system reported:"Information Alert - Status : 504 Gateway Time-Out -
Description : Lost connection to origin server". The site worked on a second attempt. While the text versions of the warning messages were readable, the HTML versions were blank, with the PTWC page header and side menu, but no warning message. On examining the HTML source code I found a large amount of formatting information and text about last year's tsunami exercise and awareness month commented out, but no current tsunami warning. It is not clear if this excessive formatting and redundant information caused the problem with displaying the message, but it would place an additional and unnecessary load on the system. This problem was previously identified 9 January 2009.

I will be discussing this issue at a seminar on a "National Bushfire Warning System" at The Australian National University in Canberra on 16 April 2009.
