JRC Tsunami Propogation Model

JRC Tsunami Propogation Model

The JRC has developed a Tsunami modelling web service, which (I’m very proud to say) makes use of worldKit for animating tsunami model results and referencing stored requests.

A model for Tsunami propagation has been developed by JRC. The model allows to predict the propagation wave once the initial location of the earthquake is fixed. The model, in contrast to other detailed 3d models, is extremely fast but sufficiently precise that can be integrated in the Global Disaster Alert System to give a first estimate should the conditions favour a Tsunami

Here is a sample animation of a simulated tsunami using worldKit. The RSS backing the simulation uses the new <geo:polygon> tag, a list of lat/long/alt triples supported in beta for worldKit.

Incredibly, this online simulation service, plus earthquake rss feeds, could provide the core resources for a tsunami warning system today. Monitor the quake RSS for magnitude 7 or greater events. New tsunami simulations can be run simply by GET request. Pass in the lat/lon from the quake RSS, and an email address to receive the results. In about 20 seconds, an email is sent with a link to the results. Parse that email to get the link, and from it determine the link of the simulation’s RSS feed. Download that feed, and you have the coordinates for the area of possible impact for the next 9 hours.

Provide a service for people to register their location. If that location resides within a tsunami warning area, send an email or text. Not sure if I’d depend on a web hacker level service for an emergency response system, but it is a compelling idea to bypass complex web service orchestrations and mapping protocols, especially when there is still no official system in place.

The JRC is working on integrating this simulation into a robust warning system, including gov’t and response agencies. And further confirmation of the model.

One major issue for a tsunami hackers alert service, discussed in their system analysis is that the tsunami epicenter and earthquake epicenter can be widely different; the Indian Ocean tsunami was centered on the midpoint of the fault on which the earthquake took place.
