Professor Charitha Pattiaratchi, Leader of the Coastal Oceanography Group at the School of Environmental Systems Engineering of the Australian National Facility for Ocean Gliders carried out a real-time analysis of the tsunami alerts and warnings around the Indian Ocean basin following the massive Bengkulu earthquakes off the coast of southern Sumatra, Indonesia on 12 September, 2007. In his paper, Pattiarachi discusses background for tsunami generation, the present status of the tsunami warning system for the Indian Ocean, and the role of deep-water tsunameters in the detection of tsunamis on 12 September. For more details, see Indian Ocean Tsunami Warning System: Example from the 12th September 2007 Tsunami.
It has been a practice at LIRNEasia to write an assessment of the responses to potentially tsunamigenic events in the region. We commented on Nias and Pangandaran. Now that the discussion on the response is starting, here is our take: Lessons from the Sri Lanka tsunami warnings and evacuation of September 12-13, 2007 The tragedy of the 2004 Indian Ocean tsunami was the absence of any official warning. The September 12th Bengkulu earthquake shows that this is unlikely to be the case in the future. We have seen that the new institutions created since the 2004 tsunami have the will and the capacity to act.
BBC NEWS | Science/Nature | Tsunami concern for Bay of Bengal Now, Phil Cummins, lead author on the Nature paper and a geologist at Geoscience Australia, believes this is not the case.He said: “I reviewed the geological literature and found the evidence for a lack of tectonic activity along the Myanmar coast was not compelling.” Historical evidence Recent GPS data, he said, suggested that the plate boundary was at sea in this area, hidden below thick layers of sediment.
Second Tsunami-Detection Station To Bolster Indian Ocean System As part of the U.S. effort, in December 2006, NOAA experts and Thai government officials put a deep-ocean assessment and reporting of tsunamis (DART) station in the Indian Ocean, halfway between Thailand and Sri Lanka. (See related article.)DART systems provide real-time tsunami detection as waves travel across open waters, and each station is linked to a satellite for real-time data transmission on global networks.
Smith Dharmasarojana is a hero to those in the disaster risk-reduction field. He was the Met Chief who raised the flag re a tsunami hitting Thailand well before 2004 December. He lost his job as a result. When the 2004 Indian Ocean tsunami did hit, he was recalled and made the disaster-preparedness czar. Because of his drive, Thailand is among the best prepared for a tsunami or similar disaster today.
Serving Sri Lanka: Indian Ocean tsunami warning capabilities improving Addressable satellite radio sets were found to be the best alerting technology of the community disaster warning pilot project conducted by LIRNEasia and Sarvodaya. Java enabled mobile phones which has a wake up siren came next. The GSM based remote alarm device developed locally by Dialog Telekom, MicroImage and University of Moratuwa followed closely. It has both light and siren.Findings of this project on learning how information-communication technologies and community based training can help in tsunami and other disaster situations had been discussed by community leaders and international experts at a workshop on “Sharing Knowledge on Disaster Warning with a Focus on Community-Based Last-Mile Warning Systems” at the Sarvodaya Headquarters in Moratuwa recently.
By Rohan Samarajiva The findings of a pilot project on learning how information-communication technologies and community-based training can help in responding to disasters such as tsunamis were discussed by community leaders and international experts at a workshop on “SHARING KNOWLEDGE ON DISASTER WARNING, WITH A FOCUS ON COMMUNITY-BASED LAST–MILE WARNING SYSTEMS” held on March 28th and 29th, 2007 at the Sarvodaya headquarters in Moratuwa. These finding ranged from the difficulties experienced in communicating disaster warnings to villages when mobile GSM and fixed CDMA telecom networks were not functional due to conflict conditions to the importance of not leaving newspapers on top of sensitive electronic equipment which can overheat and shut down as a result. In terms of the five communication technologies that were evaluated across multiple criteria, the addressable satellite radio sets and the java-enabled mobile phones performed the best, with the GSM-based community warning device developed locally by Dialog Telekom, MicroImage and University of Moratuwa following closely. The VSAT based warning system did not perform too well in the tests. The objective was not to declare a winner among the technologies, but to find out how they could be improved to perform reliably in the difficult conditions of Sri […]
In the aftermath of the 2004 Indian Ocean tsunami, the World Dialogue on Regulation carried a discussion on regulatory responses to disasters. It appears that this discussion has continued relevance to developed countries as well, as seen in this communication from the National Regulatory Research Institute in the US: “Severe January ice storms left over 450,000 customers from Texas and Oklahoma to Michigan, New York, and New Hampshire without power. In Oklahoma, sleet and freezing rain built up ice four inches thick, bringing down trees and power lines, leaving some customers without power for as much as a week. Commissions typically investigate a utility’s response to a long-term major outage, and these severe winter storms will cause regulators to refocus on outage management and restoration issues. An ongoing NRRI study on electricity outages recommends that regulators make their expectations of electric utilities more specific and investigates regulatory approaches that encourage adoption of efficient outage management and restoration systems.
Straight talk from the head of Thailand’s National Disaster Warning Center. This is even more reason for Sri Lanka to improve its national and last-mile warning systems. Phuket Gazette – online English newspaper for Phuket, Thailand, with daily news, classified ads, yellow pages, business listings, upcoming events, event calendar, phuket events Because of its location, the lone tsunami direct detection buoy deployed last month in the middle of the Indian Ocean would offer little advance warning to Phuket in the event of another tsunami generated off the Indonesian Coast, Dr Smith Dharmasaroja, head of the National Disaster Warning Center (NDWC) in Nonthaburi, has told the Gazette.Dr Smith said that the location of the first buoy was chosen so that it would provide equal benefit to all Indian Ocean Rim countries, not just Thailand. “I made the suggestion that we put the first buoy there so that we wouldn’t appear selfish by putting our own data needs before that of other countries in the region,” he said.
The views of the joint coordinator of the Post-graduate Degree Program on Disaster Management at the University of Peradeniya. Two years on: How safe are we from a future tsunami? In connection with early warning, it must be added that the Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific and Cultural Organization (UNESCO) has been coordinating the efforts of the international community led by the Government of the United States of America to develop a tsunami early warning system for the Indian Ocean, similar to that currently used in the Pacific, by the end of 2007. The proposed Indian Ocean Tsunami Warning Network, though by no means a foolproof system, will help improve Sri Lanka’s tsunami early warning capability and reliability. Yet, the more difficult and challenging task will be the dissemination of such tsunami warnings fast and effectively to the vulnerable communities so as to enable their evacuation to safe locations before the arrival of the tsunami.
According to the Independent, Sri Lanka is the best prepared to communicate tsunami warnings to at-risk populations on the coast. We wish to believe this. But unlike the highly-trained journalist from the Independent, we have taken the trouble to ask a few questions: 1. Does Sri Lanka have a single national multi-hazard warning center? NO.
Indian Ocean tsunami warning system on slow track: Tsunami Warning Remains Elusive – Council on Foreign Relations The wave which swept so many away two years ago (BBC) has faded from memory in many parts of the world, even though as many as two million people remain in temporary shelters in parts of Indonesia, Sri Lanka, and the Maldives. But surely the less onerous task of setting up a skeletal tsunami warning network must be well along, right?Not quite. While enormous sums of aid flowed in for relief and reconstruction efforts, the less glamorous work of positioning seismic warning buoys around the rim of the Indian Ocean lags financially and organizationally. As this new Backgrounder explains, several piecemeal systems are up and running, but the goal of creating an Indian Ocean early-warning system to rival the ones run by the United States and Japan in the Pacific remains a long way from being reached (TIME).
Several weeks ago we speculated on why the Maldives, with its tiny population, needed two undersea cables. The answer is that the first cable is a collaboration between the new entrant Wataniya and India’s disruptive competitor, Reliance (through its FLAG unit). This created enormous pressure on the complacent incumbent Dhiraagu, the result being the cable to Colombo. LANKA BUSINESS ONLINE – LBO A new fibre optic undersea cable that connects Maldives to Sri Lanka will bring down international call charges from the Indian Ocean coral atoll, officials said Tuesday.Until the cable was commissioned this month, bilateral traffic of 600,000 minutes per month was routed via more expensive satellite links.
One hour warning possible for tsunamis originating from the Sunda Trench. What we do with that one hour is the key question. People’s Daily Online — Nations progess on tsunami detection Thailand launched the first of 22 US-made tsunami-detection buoys to be positioned around the Indian Ocean as part of a regional warning system against giant waves caused by earthquakes under the sea. The satellite-linked deep-sea buoy, unveiled at a ceremony on the tsunami-hit island of Phuket, will float 1,000 kilometres offshore, roughly midway between Thailand and Sri Lanka. “This will give us the capability to provide 1 hour warning to most of the countries in the northern part of the basin,” Curtis Barret of the US National Oceanic and Atmospheric Administration said.
Early warning regarding tsunamis depends on skilled interpretation of earthquake data from seismic monitors like the one at Pallekale and data from ocean based buoys that detect fast moving bodies of water. The ocean between Sri Lanka and Thailand now has one. It is up to us to make sure that the warning that get communicated from international and regional warning centers will be communciated to the affected communities promptly and that those communities will be prepared to respond properly. NOAA Provides First Tsunami Detection Buoy for the Indian Ocean: Financial News – Yahoo! Finance Following a ceremony in Phuket, Thailand, where the 2004 Boxing Day event caused the most extensive tsunami damage in Thailand, the MV SEAFDEC set sail today to deploy the buoy about mid-way between Thailand and Sri Lanka.
LIRNEasia, Sarvodaya and the partners of the HazInfo project have been saying this and more importantly implementing this. Hope the message will be heard. Reuters AlertNet – News – Prevention spending must be doubled Governments, aid agencies and humanitarian actors must spend twice as much on disaster preparedness activities that could save millions of lives, the British Red Cross has urged.Almost two years on from the devastating Indian Ocean tsunami, risk reduction remains low on the international agenda despite encouraging progress in tsunami-affected regions themselves. “The tsunami highlights the importance of proactively preparing for disasters and this lesson must be learnt and risk reduction must become a high priority in all disaster-prone areas,” said David Peppiatt, British Red Cross head of policy.
