Diana Roman, a volcanologist at the Carnegie Institution for Science, discusses the dramatic increase of nearly 2,000 earthquakes in Iceland, signaling potential volcanic unrest. She explains how the seismic activity reflects magma moving closer to the surface. The conversation highlights the unique geological features of Iceland, where tectonic plates meet magma plumes, creating a hotspot for earthquakes and eruptions. Roman also clarifies the nature of earthquake swarms and the hazards posed by an impending eruption, especially if it occurs underwater.
