Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, ... These mountains are entering the subduction zone and are melting.

Subduction zone volcanoes commonly exhibit a symmetric shape with steeper slopes near the vent and a broad gentle base. These stratovolcanoes produce a wide range of volcanic products including ...

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal ...

Magma released where tectonic plates collide at subduction zones appears to take an unexpected and circuitous route to the surface — a ... was based on seismic scans of a volcanic arc in the ...

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

The resulting geohazards include the largest earthquakes and tsunamis, active chains of volcanoes, and large landslides. Many large population centers are situated along subduction zones and are ...

Although Merapi is a well-studied volcano and has a well-known eruptive history [4], the proposed magma storage is complex [4,5]. However, the cutting-edge microanalytical work which the student will ...
