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 ...

El Misti, also known as Putina, is a stratovolcano located in southern Peru, near the city of Arequipa. It is a symmetrical, snow-capped cone that stands at 5,822 meters. It is considered active, though its last major eruption occurred in ...
The Richter scale “saturates” (fails to distinguish) between very large earthquakes (above 7.0) because it only measures peak wave amplitude. The Moment Magnitude Scale (Mw) measures the total energy by considering the fault area and the amount of slip, providing ...
The line connecting places in a region where an earthquake is experienced at the same time is technically called a Coseismal line. It maps the “arrival time” of seismic waves. However, in many contexts, the isoseismal line is used to ...
The earthquake focus is technically defined as the point within the Earth’s lithosphere where the stored elastic strain energy is first converted into seismic energy. It is the location of the initial break along a fault plane. From this point, ...
