What are these monkeys doing in our blog?

on July 30, 2008

To an ordinary observer the image on left looks like some monkeys but to Nuwan Waidyanatha that is his complex Early Warning System. Monkeys act as sensors and detectors of hazards (aka a leopard) to deer – who would take immediate action for mass evacuation.

Again the image on top right look likes a damper to any engineering student, but to Nuwan that is mass evacuation. The figure below might explain it better with the blue line representing a quick but rough evacuation and the red line a smoother one.

What does this figure has to do with Broadband QoS? If the zero line is assumed to be the accepted level, this explains the change in QoS with the growth of markets. Initially it is the best with…

Are early warning systems gender biased?

Rohan Samarajiva

on October 22, 2007

The article below (issued to mark International Day for Natural Disaster Reduction, 11 days late) says that the manner in which warning are communicated “typically disadvantage women.” The “evidence” or illustration used to support this broad claim is strained, to say the least. Our experience with the HazInfo project in Sri Lanka was quite the opposite. It will be interesting to see what others think.

OneWorld South Asia Home / News:Opinion & Comment - Disaster lessons from the past

Early warning systems are critical to reducing the impact of floods, droughts, hurricanes, tsunamis and other disasters. However, the ways in which warnings are relayed typically disadvantage women and their ability to respond to the disasters.

For example, in one fishing village in Peru prior to an extreme El…

Significant progress made on making communities resilient to disasters

Nuwan Waidyanatha

on April 1, 2007

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 28^th and 29^th, 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…

Disaster preparedness, not just relief: Indian PM talks the talk

on November 30, 2006

Very good.

Now will the Indian government walk the walk?

Will the other countries take the lead?

Govt. committed to develop a robust disaster management system: PM

Addressing the First India Disaster Management Congress here, Dr. Singh called for a paradigm shift in disaster management from a “relief-centric” and “post-event” response.

Pointing to the draft National Policy on Disaster Management, he said that it placed greater emphasis on efficient management of disasters, rather than focusing only on immediate response to disasters.

“Such an approach should place emphasis on improving early warning systems, ensuring the reach and efficacy of dissemination, creating awareness and building capacities at all levels of public administration,” he said.

Learning to Respond Intelligently

Nuwan Waidyanatha

on July 29, 2006

Often a response is a result of a stimulus. Evacuation drills are stimulus-response models; the drill is activated by a siren and the people are expected to react by hurrying to safety zones, in most cases defined by the community’s response plan; i.e. activating an existing emergency response plan.Social Cognition is encoding, storing, and retrieving social information and applying the cognition to social situations. Consider the social situation of a disaster and the event of setting of sirens. The awareness programming in community risk reduction helps the community prepare for social situations. Cognitive representation of social information are schema.

Biological Psychology defines “Awareness” as a human or animal perception and cognitive reaction to a condition or event; awareness does not necessarily imply understanding.

First Phase of HazInfo Project Completed

Indi Samarajiva

on May 19, 2006

The first phase of the Last-Mile Hazard Information Dissemination (HazInfo) project funded by IDRC, was completed recently with the training of trainer component. LIRNEasia is implementing this project along with its project partners Sarvodaya, the largest community organization in Sri Lanka and TVE Asia Pacifi c (TVEAP), a non-profit media organization working in the Asian region.

LIRNEasia has undertaken a number of initiatives in the area of ICTs disasters and early warning post the Indian Ocean tsunami disaster of 2004. However, this is by far the largest project undertaken LIRNEasia in this area to evaluate the suitability of a number of ICTs (information and communication technologies) deployed in varied conditions for their effectiveness in the last-mile of a hazard warning system.

Information sought on siren systems and school drills for tsunami preparedness

Rohan Samarajiva

on March 29, 2006

An AFP report states that:
UN Under Secretary Patricio Bernal said Egeland and former US president Bill Clinton had taken to task government officials from countries in the Indian Ocean in a closed-door meeting here in a bid to speed up the process. “We are not worried about the technical side. At the moment we have 17 sensors in the Indian Ocean and by July we will have 23. If anything happens tonight, somebody will be there to move an alert,” he told AFP.
“What we are afraid of is whether this information will flow down. The countries have not done enough. There is a lack of political will,” he said. He praised Sri Lanka for setting up siren systems and drilling school children, but said all…

Mapping disaster research

NSF EXPLORATORY WORKSHOP ON SENSOR BASED INFRASTRUCTURE FOR EARLY TSUNAMI DETECTION, Maui, Feb 9-10, 2006

What I learned during my visits to the Civil Defense Center and the Tsunami Museum in Hilo and the Pacific Tsunami Warning Center in Ewa Beach in Hawai’i last January greatly contributed to the disaster communication research program undertaken by LIRNEasia in the aftermath of the 2004 Indian Ocean tsunami. Therefore, I welcomed the opportunity to step back and reflect on the research program a year later, also in Hawai’i.

The occasion was a workshop funded by the National Science Foundation of the US. It was organized by Louise Comfort, Daniel Mosse and Taieb Znati, all at the U of Pittsburgh. Louise is from Public Policy and has been working on disasters for…

Tsunami Lessons

Ten preliminary lessons of the 28th March 2005 Sumatra great earthquake (Photo Source)

LIRNEasia, together with Vanguard Foundation, intends to systematically analyze the Sri Lankan media response to the great earthquake of the 28th of March. However, it appears useful to draw some preliminary lessons from this tragedy which has cost over 1,000 lives, including the people of Nias and other islands and those in Sri Lanka and elsewhere who died as a result of the warnings. The conclusions are preliminary; comments are welcome.

# Earthquake hazard detection is easy; tsunami hazard detection is not. One cannot simply infer the existence of a destructive tsunami from an earthquake. Whether a tsunami has been generated and the direction it is likely to go requires the application of expert judgment.

SMS as part of Early Warning System

SMS enlisted for Tsunami warning system?

By Ben Charny, CNET News.com
Monday, January 10 2005 11:55 AM

At least five countries have begun developing an alert system using cell phone text messages, a response to the catastrophic Asian tsunami that exposed flaws in present-day early warning schemes.

Discussions among officials in India, Indonesia, Sri Lanka and Thailand, which were hard hit by the killer tsunami, along with France, have begun in just the last few days, according to a source familiar with the plans.

The goal is to supplement older systems that proved little help for nations in the path of the immense waves in late December that have so far killed more than 140,000 people in 11 countries. Already emerging from the wreckage are tales of emergency workers and…
