Volcano seismologists study several types of seismic events to better understand how magma and gases move towards the surface: Volcano-tectonic (VT) earthquakes represent brittle failure of rock, the same process that occurs along purely "tectonic" faults such as the San Andreas Fault. At volcanoes, VT events can occur due to "normal" tectonic ...Why Do Earthquakes Happen? Most faults in the Earth’s crust don’t move for a long time. But in some cases, the rock on either side of a fault slowly deforms over time due to tectonic forces. Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the ...PHIVOLCS Earthquake Bulletins of latest seismic events in the Philippines are listed below.
