Detailed explanation-1: -The Philippine Institute of Volcanology and Seismology (PHIVOLCS) is a service institute of the Department of Science and Technology (DOST) that is principally mandated to mitigate disasters that may arise from volcanic eruptions, earthquakes, tsunami and other related geotectonic phenomena.

Detailed explanation-2: -The Philippine Institute of Volcanology and Seismology (PHIVOLCS) is responsisble for forecasting volcanic eruptions and earthquakes; and determining how they occur and what areas are likely to be affected.

Detailed explanation-3: -The USGS Volcano Hazards Program monitors volcanoes to detect signs of change that forewarn of volcanic reawakening.

Detailed explanation-4: -These stations are equipped with seismometers that detect and record earthquakes. Data is sent to the PHIVOLCS Data Receiving Center (DRC) to determine earthquake parameters such as magnitude, depth of focus and epicenter.

Detailed explanation-5: -Perceptible to people under favorable circumstances.

Detailed explanation-6: -JMA operationally monitors seismic and volcanic activity throughout the country and issues relevant warnings and information to mitigate damage caused by disasters related to earthquakes, tsunamis and volcanic eruptions.
