IFEQ, app developed based on the J-SHIS system

Abstract:

Raise an awareness of earthquake disaster prevention is an important issue in Japan. To do that, we have developed an app IFEQ on smartphone based on the APIs provided by the J-SHIS that is an integrated system of Seismic Hazard Assessment. IFEQ can simulate a real situation of earthquake disaster you might experience at current spot. The hint of the IFEQ came from a question “What should I do IF a big EarthQuake hit now?”

An earthquake risk situation is estimated by a location information that is acquired from GPS, the detail comprehensive information of a 250m mesh obtained through J-SHIS APIs by the geomorphological classification and a probability of intensity 6 lower (JMA) within 30 years. A user’s photo was displayed with a risk situation surrounded by simply one touch.

IFEQ helps oneself to overcome a gap between exist scenes and a horrible disaster by enhancing imagination. The results show people have more ideas to handle with the risk situation after using the App IFEQ.

IFEQ App’s features are summarized as below:

1. Visualizing an image photo with possible risks from a coming earthquake at present spot.

2. Displaying an exceedance probability within 30-years and a maximum seismic intensity within 10,000-years on present location.

3. User can obtain some advices of how to prepare for possible risks.

4. A risk with five ranks is given, especially for items of Building Collapse, Liquefaction and Landslide.
