The TsuHaMEI (Tsunami Hazard Map Enhancement using Interferometric Synthetic Aperture Radar (IfSAR)) Project of the Philippine Institute of Volcanology and Seismology (PHIVOLCS), initiated in 2016, aims to refine 1: 50,000 scale Philippine tsunami hazard maps, which were previously generated under the DOST-GIA Tsunami Project in 2007 and the READY Project from 2007 to 2013.

The TsuHaMEI Project finetunes tsunami inundation extent defined by previous projects by utilizing topographic contours extracted from 5m x 5m resolution 2013 IfSAR digital terrain model which has recently been available in the country. Resulting enhanced tsunami maps now indicate one-meter-interval tsunami wave height gradations, unlike previous maps which only showed generalized inundation areas. Maximum tsunami inundation distances and wave heights are adopted from previous results that used empirical and modelling techniques.

For the period 2016-2017, a total of 22 out of 67 tsunami prone provinces would have been completed. The maps are distributed to respective local government units for their use for local disaster mitigation and preparedness planning.
