The MV SHOW it Project (Maps of Volcanic and Seismic Hazards On the Web) started in 2014 with the purpose to: (1) standardize 1:50,000 quadrangle scale hazard maps; and (2) make this information available online through the PHIVOLCS website. The project connotes a journey towards showing all available volcano- and earthquake-related hazards information online, servicing all its stakeholders in a more efficient way.

For the last two years, MV SHOW it has spearheaded standardization of hazard maps derived from the READY Project. It produced more than 800 images of 1:50,000 scale hazard maps.

In order to showcase hazards information on the web, it partnered with NAMRIA's (National Mapping and Resource Information Authority) Philippine Geoportal: One Nation One Map Project, and the Geological Society of Japan (GSJ). Partnership with NAMRIA resulted to the PHIVOLCS Geoportal and collaboration with GSJ made the progress of The PHIVOLCS Faultfinder possible. NAMRIA and GSJ developed the applications while PHIVOLCS manages, maintains and manipulates hazards information in its own server. Both applications utilize base maps provided by NAMRIA

The PHIVOLCS Geoportal app displays all available 1:50,000 scale earthquake-related and volcano-related hazard maps in the Philippines, as well as other geospatial information available in the Institute while the PHIVOLCS Faultfinder displays the distance of a user's location with respect to nearby active faults. Active faults shown in the application are results of various active fault mapping projects conducted by PHIVOLCS or in collaboration with international partners since the 1990s.

The MV SHOW it Project has also already started standardizing hazard maps in other relevant map scales, and has initiated ways to pro-actively engage its stakeholders through more user-friendly WebGIS and mobile applications.
