Though immensely powerful, volcanoes are not always spewing hot lava around. Many are considered dormant or even extinct and have not shown their strength for hundreds of thousands of years in some cases. However, a team of scientists recently found magma chambers lurking beneath six volcanoes in the Cascade Range. The findings published January 23 in the journal Nature Geoscience are challenging the idea of what separates an active volcano from…

Magma chambers found lurking in dormant volcanoes

View at EarthSky Community Photos. | Jeremy Likness took this photo on July 24, 2023. Thank you! This is a view of Mount Rainier in Washington. Rainier is one of the Cascade volcanoes in the Pacific Northwest. A new study said the Cascade volcanoes, though mostly dormant, still hold large pools of magma beneath them. The 2025 EarthSky lunar calendar makes a great gift. Get yours today! Magma still sits under Cascade volcanoes The Cascade volcano…

Cascade volcanoes still have large pools of magma

New Cornell University led-research challenges the long-standing belief that active volcanoes have large magma bodies that are expelled during eruptions and then dissipate over time as the volcanoes become dormant. Researchers used seismic waves to identify magma chambers beneath the surface of six volcanoes of various sizes and dormancy within the Cascade Range, which includes half of the U.S. volcanoes designated by the U.S. Geological Survey …

Magma reservoirs beneath volcanoes along the Cascade Range arc vary in depth, size and complexity, but upper-crustal magma bodies are widespread, according to a team of geoscientists from Cornell University and Cascades Volcano Observatory. The post Geoscientists Find Large Bodies of Magma beneath Dormant Volcanoes appeared first on Sci.News: Breaking Science News.

Magma found beneath dormant Cascade volcanoes

Recent research conducted by a team from Cornell University is overturning existing paradigms about the relationship between active volcanoes and the magma bodies beneath them. Traditionally, it was widely believed that active volcanoes possess large reservoirs of magma that are expelled during eruptions. Once these eruptions occur, the magma would gradually dissipate over time, leading to the volcano’s dormancy. However, this new study challeng…

Substantial Magma Reservoirs Discovered Beneath Dormant Volcanoes,

Research from Cornell University and the U.S. Geological Survey (USGS) identifies extensive magma chambers beneath numerous volcanoes along the Cascade Range. The findings, published in Nature Geoscience on January 23, reveal active magmatic systems between 5-15 kilometers beneath mountains long considered dormant. The research team investigated six major volcanoes spanning Washington, Oregon, and California: Mount […] The post Massive Magma Cha…
