Why Deep-Focus Earthquakes Occur and Their Connection to Rising Magma

Deep-focus earthquakes are seismic events that occur at depths greater than 300 km below Earth’s surface, sometimes reaching 700 km. Unlike shallow earthquakes, which are linked to surface faults and…

Signs of Magma Rising from the Mantle to the Surface

One of the clearest indicators of magma movement is seismic activity. As magma pushes through cracks in the Earth’s crust, it causes small earthquakes called volcanic tremors. Scientists monitor changes…
