TERRI monitors for you the natural disasters


Terri now focuses on monitoring EARTHQUAKES. But that's only the beginning... volcanoes, tsunamis and other natural disasters will gradually enrich the world of Terri.


Terri updates every 5 minutes the information provided by the USGS (U.S. Geological Survey) and EMSC (European Mediterranean Seismological Centre) web sites. And because it is essential that you know the age of the information displayed, Terri tells you at any time when the last refresh was and alerts you as soon as the application is no longer connected to the Internet. Of course, you can refresh this information whenever you want.


Display the earthquakes that occurred in the last 24 hours, last 7 days or last 30 days, the choice is yours ! You can also sort them by date, magnitude, distance from your position or by region.
