👉 Semivolcanically is a term used in geology and volcanology to describe the process by which magma or lava rises from the Earth's surface due to high pressure and temperature. In this process, magma or lava typically cools rapidly, releasing heat and energy into the atmosphere as it erupts, creating a seismic wave that can travel long distances. Semivolcanically refers to the phenomenon of volcanic activity occurring in a region where magma is released from the Earth's surface at high pressure and temperatures
