In 2007 Smith Dharmasaroja, the former disaster czar of Thailand, pointed to the dangers posed by mountains of mud deposited by the Ganges in the Bay of Bengal. What the research below raises is the danger of soft material combined with earthquakes. Are these not high priority research areas for our scientists? In a paper published today (24 August 2012) in the journal Earth and Planetary Science Letters, Professors Dan McKenzie and James Jackson of Cambridge’s Department of Earth Sciences describe for the first time the added factor that may have made this tsunami so severe: a huge collapse of soft material on the sea bed resulted in a far greater movement of water than would have been caused by the earthquake alone. Full report.
Yesterday, I was talking with an Indian colleague who was involved in improving the Indian weather information system based on INSAT while working for the Indian Space Research Organization (ISRO). The trigger had been the devastating cyclone that hit Andhra Pradesh in 1977. This was also related to initiating my interest in disaster early warning because that cyclone was supposed to hit the East Coast of Sri Lanka, but veered away at the last minute. I remember tracking news of its journey while working at the Sri Lanka Broadcasting Corporation. One year later the cyclone did not change track and we lost over 900 people on the East Coast.
There are complexities in interconnecting agencies but more at the social layers than at the technology layers. The Simon Fraser University (SFU) Mobile Communications (MobComm) Truck was designed to patch a Regional Emergency Operations Centre (REOC), specifically the British Columbia Provincial REOC (termed as the PREOC) communicating through the Internet (TCP/IP) and public telephone lines (PSTN). The first-responder (e.g. forest firefighters) naturally communicate with Ultra High Frequency (UHF) radio sets.
I was pleased to read that detection devices for nuclear hazards are to be set up in Sri Lanka, even if it was from a foreign publication. I have been one of the few to point out that Sri Lanka lives in the shadow of nuclear reactors, while getting none of the benefits. This announcement indicates that someone in authority is paying attention. Following the request of AEA, International Atomic Energy Authority (IAEA) decided to help Sri Lanka set up seven early warning detectors and provide equipment worth 72,000 Euros, said Warnakulasuriya. “With nuclear leakage at Fukushima in Japan last year the region felt the need for nuclear disaster warning systems.
People in Sri Lanka felt the tremors from the April 11, 2012 tsunamigenic earthquake. Reports indicate that, before the Government of Sri Lanka could issue any kind of bulletin, within 10-15 minutes of the tremors, people were receiving tweets of the event. Samarajiva wrote – “Tweets kept flying. I and several others active in social media kept emphasizing that only a “watch” existed, that people should be alert and not do anything for now”; see full article in LBO. However, does twitter reach all Sri Lankans?
LIRNEasia’s thinking, right along, has been, if one is prepared to appropriately warn of rapid onset tsunamis then they are quite ready for all-hazards. Then why did the already established warning centre fail on 2011 November 21. Preparation, Warning, and Response are three linked components of the Disaster Management life-cycle common to all-hazards. Development of systems for those three components in relation to tsunami warnings can be extended to all-hazard early warnings. Question is “how does one extend those capabilities to avoid missing deadly alarming events beyond tsunamis such as the 2011 November 21 Matara Mini Cyclone as well as reduce the false warnings?
The 3rd LIRNEasia Disaster Risk Reduction Lecture will be held on 19 June 2012, Tuesday at 1500 hrs at the Sri Lanka Foundation Institute, 100 Independence Square, Colombo 7. The main talk by LIRNEasia Senior Research Fellow Nuwan Waidyanatha on “making emergency communication effective” will complement the opening presentation by the Director General of the Sri Lanka Disaster Management Center on the Sri Lankan tsunami warning system. It will highlight how the DMC can better perform its role in emergency communication and coordination. There are complexities in managing multiple agencies and offering a common platform to manage all-hazards all-media alerting and reporting. Possibly the harder problem may be the social elements.
In order to establish the fact that the voice quality over currently available GSM networks are poor for converting the voice messages to text. These finds are from the Voice-enabled ICTs for Disaster Management project that field tested the use of an Interactive Voice Response system for extending emergency communications to the last-mile. Situational reports received from Community Emergency Response Team members, through their mobile phones, resulted in an Mean Opinion Score (MOS) of less than 4.0, on a scale of 1.0 – 5.
Patrick Gannon (President & CEO, Board Director at OASIS), in an email, “You provide some very interesting information on the open source Sahana effort and examples of using citizen volunteers for disaster situation reporting. The issue is being highlighted in the 2012 CAP workshop FINAL REPORT.” Get more details on the voice-enabled alerting and situational reporting project from the video: “Do you hear me?” The Common Alerting Protocol (CAP) community has nick named us “CAP early adopter” (lol & \0/). This is because in 2005 when the CAP content standard was first released, LINREasia was quick to test it in the HazInfo project.
Senior Research Fellow Nuwan Waidyanatha recently completed an action research project on how local-language voice communication can be used in early warning and other disaster management tasks. A 10 mt video has just been released.
After watching the video, please take a few minutes to complete this questionnaire (there are only three simple questions to answer). You may scroll to the bottom to access the questionnaire; else click here. Thank you in advance. With the spread of affordable telecom services, most Asians now use their own phones to stay connected. Can talking on the phone help those responding to emergencies to be better organised?
Every where Government agencies are territorial and fear losing their budgets and ability to stand ground. Therefore, choose to work as a silo with less lateral integration. Such structures are ineffective and lead to irresponsible behaviour at the expense of causing havoc on the citizens. Time and time again we hear of the shortcomings arising from unplanned and ad-hoc procedures carried out in the presence of hazard events. The past experience being the 2012 April 11 Sumatra earthquake.
David Ebert, the second keynote speaker at the ISCRAM2012, in his talk says – “Recently, big data analytics has become the buzz in international news and corporate campaigns as the technology to change the future. However, while necessary in our modern data deluge of over one zetabyte of digital data, the common big data analytics approach tends to utilize only computational power and algorithms to turn data into information and then knowledge and provide an answer to the responder or decision maker using the system. In contrast, visual analytics capitalizes on the best and complimentary abilities of both components of the human-computer decision-making process through iterative, interactive visual interfaces to leverage and supplement the cognitive capabilities of the human user.” In our Real-Time Biosurveillance work, this is exactly what we did; thus, take the over 100s of records coming from each clinical facility every day, then present them to Epidemiologists using temporal and spatial data visualization methods offered by the T-Cube Web Interface. Additionally, provide them with tools to drill into and apply statistical analyses methods to look for unusual patterns in the large data set.
Francis Boon presented the LIRNEasia and Sarvodaya conducted feasibility study at the CDAC Media and Tech workshop in London.
An earthquake happened. Minor tsunamis occurred with no loss of life. The story was in the warnings and responses. My first (and obviously imperfect) reflections are in LBO. In the age of social media, people will learn of distant hazards independently of government.
How does one plan for 97 feet high tsunami? The scale of the possible tsunami trumps all previous notions of the risks facing the town. Deadly tsunamis have been rare here; the last few waves to reach Kuroshio, including one in 1946, did little damage. Town officials are not entirely blind to the risks of sitting on a shoreline facing one of the world’s most active seismic rupture zones. Two years ago, they built a tsunami tower for residents to flee to, but it is only about 40 feet above sea level.
