The Pelean type is the most explosive due to its extremely viscous magma. This thick lava often blocks the volcanic vent, creating immense pressure from trapped gases. When the pressure finally overcomes the blockage, it results in a massive explosion ...
A seismic gap is a section of a known active fault that hasn’t ruptured in a long time compared to other segments. Seismologists believe these gaps are “overdue” for an earthquake because tectonic stress continues to build up there, making ...
The scientific study of earthquakes and the propagation of elastic waves through the Earth or other planet-like bodies is called Seismology. Experts in this field, known as seismologists, use data from tremors to map the Earth’s interior and assess the ...
A seismograph is an instrument used to detect and record seismic waves (P, S and L waves). It consists of a weighted pen or electronic sensor that remains steady due to inertia while the surrounding frame moves with the shaking ...
