This project is a design solution to alert members in a remote coastal community of an earthquake that has occurred in its broad vicinity, so they may spread the word and prepare to take precautions against a probable Tsunami. Further, we explore techniques to find patterns from mini-quakes occurring in the recent past to reasonably predict a major occurrence. Our solution is tailored keeping in mind communities that experience no or intermittent connectivity to the Internet or GSM networks.


Alerting community members living in remote coastal communities of an earthquake related Tsunami is often challenging. Let us take the example of Andaman and Nicobar islands, located in the Indian Ocean. Most parts of the island do not have internet connectivity or GSM coverage with only certain establishments in the land with access to a low bandwidth internet connection. Such regions however have a rich penetration of Cable TV and FM radio culture

In our solution, we have a node running on an open hardware Linux board connected to the internet, constantly receiving updates from the USGS earthquake feed every 5 minutes. We extract the magnitude and location of earthquakes that have just occurred, and see if it lies within a 500km radius off-coast of our location. If so, an alert is sent out as an audio message over an FM frequency. Voice alert or AFSK data is sent depending on the design of the civic media paradigm.
