Question

Increased seismicity (# quakes per day) and increased emission of gases (like carbon dioxide and sulfur dioxide) are two signs that can signal that a volcanic eruption is imminent. What is the most likely cause of these two precursors

Answer 1

Increased seismicity and increased gas emission means the building of pressure.

Step-by-step explanation:

• Various factors like the earthquakes, tsunamis, gas release, and the mid slides and the occurrences of the avalanches indicates that the ground deformations and the build of a pressure cell that is going to blow out form the weakest part of the earth.

• It can be seen through the thermal motioning systems, like those of the satellite imagery and the hydrological studies of tides and the ocean currents. Also the mass movement and raptures, rocks fall and the debris slides.
