PHIVOLCS Hazard Maps Training on Disaster Risk Reduction: The Role of DOST Regional Offices Jeffrey S. Perez Philippine Institute of Volcanology and Seismology Department of Science and Technology Objective • To know the different available hazard maps at PHIVOLCS. • To be familiarized with the contents of the different hazard maps (scale, legend, etc.).
