We have already requested a shapefile of Active Faults and Trenches within a 300 km radius of Tarlac City. However, the database files only contained the corresponding latitude and longitude for each seismic source. 

The depth of active faults will be used for the seismic source geometry of R-CRISIS software. These data will help for the continuation of our project study. 

Thank you so much. Hoping for your favorable response.
