Saturday, the entire coastal town of Grindavik, Iceland was evacuated. That's because over the weekend, the country experienced nearly 2,000 earthquakes within 48 hours. And they've kept coming since then – in swarms. Scientists think the quakes are indicative of magma moving closer to the surface in the country's southwestern peninsula and that a local volcano could erupt at any moment. Today on the show, host Regina G. Barber talks to volcanologist Diana Roman about the science behind these ea...
Nov 15, 2023•13 min•Ep 979•Transcript available on Metacast In the 18th century the world was focused on Venus.
