A six-year SAR study of ground movement around Masaya in western Nicaragua finds evidence for two active magma chambers beneath the volcano, a dual-system similar to Kīlauea. The result helps explain Masaya’s mix of lava-lake activity and explosive history and highlights ongoing hazards to nearby Managua from gas emissions and potential eruptions.
Researchers studying the Methana volcano near Athens found that despite a 100,000‑year quiescence, magma has been steadily accumulating underground, evidenced by dating zircon crystals. This challenges the idea that silent volcanoes are extinct and suggests dormant systems can store energy and pose unexpected risks, highlighting the need for ongoing monitoring and re-evaluation of volcanic hazard levels worldwide.
A recent study using earthquake wave analysis revealed large, persistent magma pockets beneath several dormant Cascade volcanoes, indicating that these volcanoes still hold significant melt at depth, which could influence future volcanic activity. The findings highlight the importance of continuous monitoring and advanced imaging techniques to better understand volcanic behavior and potential eruption risks.
