(Express) – Earthquakes have caused volcanic activity across the globe over the last 24 hours, near some of the most potentially dangerous sites on the planet. Volcanoes throughout the world have felt the repercussions of earthquakes over the last 24 hours, as a rash of activity spread to the most distant corners of the globe. The Katla volcano in Iceland, Mount St Helens in California, Kilauea in Hawaii and Etna on Sicily were among those seeing increased activity.

Some of these volcanoes saw enough seismic activity to constitute an earthquake ‘swarm’. Monitors with Volcano Discovery documented earthquakes near notable volcanoes with a magnitude of two or higher. Clear Lake volcano (California): 17 earthquakes over 23 hours, indicates possible earthquake swarm. All earthquakes in the area reached a magnitude of 1.1 or lower. – Katla volcano (Iceland): Six earthquakes under the volcano over 11 hours. READ MORE
