The Three Sisters Volcano, located in the Pacific Northwest of the United States, is undergoing an intriguing geological process: ongoing magma intrusion. This volcanic activity has captured the ...

He said the magma intrusion two decades ago appears to have set the stage for all the deformation recorded. "Modeling...suggests the 1996–2004 uplift was caused by an intrusion of magma about 14 ...

From Jan. 31 to Feb. 3, a magma intrusion into Kilauea’s flank, southwest of the summit caldera, was the focus of attention at the USGS Hawaiian Volcano Observatory (HVO).

This was happening up until Friday, November 10." However, he added: "In the other type of intrusion, magma moved very rapidly upwards and laterally, forming a vertical sheet.

At about 1:30 a.m. HST on Tuesday, that activity intensified, and it became clear that seismicity and increasing deformation were indicating a new intrusion of magma.

I chose these chronometers because their source minerals were readily available in the tonalitic wallrock adjacent to the intrusion we were studying. I also chose these chronometers because they ...

Courtesy USGS “We believe that the magma is rising about four miles below the surface. And, and so associated with that, a lot of times you’ll have very small earthquakes,” Burns said.

The 'seismic crisis' around the region of the Chiles and Cerro Negro de Mayasquer volcanoes near the Colombia-Ecuador border is likely caused by intruding magma, according to a report by R ...

A tunnel of magma, or molten rock, that extends northeast across Grindavik and some 10 km further inland, was estimated late on Saturday at a depth of less than 800 metres, compared with 1,500 m ...
