Santorini Earthquake Swarm Triggered by Magma Intrusion
What happened at Santorini Earlier this year, tens of thousands of small earthquakes rattled the iconic Greek island of Santorini, a clear sign that its volcanic system was on the move. After months of study, researchers have concluded that the swarm was triggered by molten rock pulsing through an underground conduit. This intrusion, while extensive,…

The Invisible Brake: Near-Surface Cooling Stalls Giant Dyke Swarms
Introduction: Unveiling the Hidden Controls on Giant Dyke Swarms Giant dyke swarms are among Earth’s most striking geological features: networks of long, sheet-like cracks that channel molten rock laterally through the crust. These structures play a pivotal role in how magma intrudes, migrates, and eventually erupts. Recent insights, distilled from the Journal of Geophysical Research:…

The Invisible Brake: How Near-Surface Cooling Stalls Giant Dyke Swarms
The Hidden Brake on Magma: Near-Surface Cooling and Dyke Swarms Giant dyke swarms are among Earth’s most striking subterranean features: networks of long, sheet-like cracks that channel magma sideways through the crust, helping shape volcanic landscapes and crustal evolution. A recent synthesis from the Journal of Geophysical Research: Solid Earth highlights a surprising factor in…
