The PHIVOLCS FaultFinder

About this app

The PHIVOLCS FaultFinder mobile app shows information about the distance between the user's current location, address or selected location on the map and the nearest active fault. This app needs internet connection to access the web-based active fault database of PHIVOLCS and the necessary web services. The database provides the backend source of information for the Web Map Service (WMS) and Web Processing Service (WPS) used for displaying the active fault map and querying fault trace locations, respectively. This app uses three base maps, the Philippine Geoportal Map, Google Maps and the OpenStreetMap, which are served as web services provided by the data owners. The Philippine Geoportal Map is provided by the National Mapping and Resource Information Authority (NAMRIA) of the Philippines. This app is a classic Web-based Geographic Information System (WebGIS) following the Spatial Data Infrastructure model. The FaultFinder app is the product of the joint collaboration between the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Department of Science and Technolog (DOST), Philippines and Geological Survey of Japan (GSJ), National Institute of Advanced Industrial Science and Technology (AIST), Japan. Dr. Renato Solidum, director of PHIVOLCS, initiated the idea of developing the app. The FaultFinder app was developed by Dr. Joel C. Bandibas of GSJ with the cooperation of the research and development personnel of PHIVOLCS.

Ratings and reviews

Great app for awareness. Unfortunately, the "legend" icon doesn't work. There's no way for us to know what other icons mean except for the red line, which is obviously the fault line.

I read some reviews that it's slow. I think they have updated the app now, and I was able to get my results quickly. Thank you, this is informative and helpful.

What is wrong with you guys? I've been using this app ever since the web version stopped working, and then this app also stopped working on my Huawei P20. I eventually found out that it's no longer compatible with my phone. So now, the app just decided to be very picky with devices? I just wanted an informative app to address my concerns about earthquakes and fault lines. Stop risking other people's lives by making your app useless. I might as well switch to other apps at this point.
