We designed a seismic intensity meter and a data collection network for use in the Philippines. The station unit deployed consists of a digital acceleration sensor with 0.1 gal noise and a compact Microsoft Windows PC. The station unit, which is designed to be installed in local government offices, calculates values every 10 seconds for the PEIS (Philippine Earthquake Intensity Scale), and these values are shown on a display and transmitted to the main PHIVOLCS office over the Internet. One hundred units to be deployed throughout the country are now being distributed to offices.
