The likelihood of an eruption has decreased from March, but the volcano remains at an elevated level of unrest and an explosive eruption (or eruptions) like those that occurred in 1953 and 1992 is ...

Although volcanic eruptions can strike when least expected, they sometimes give off warning signs that can be captured by advanced technology. One innovative way to monitor eruptions is now being put ...

The largest volcanic eruption in human history resulted in a few years of warm weather, according to an analysis of ancient sediments, and not a severe volcanic winter as some researchers had thought.

In 2024, sensing technology developed at Caltech was deployed in the region to study the motion of subsurface magma and its eruption into lava on the surface. Using data from the technology ...

The recent eruptions of Poás Volcano in Costa Rica have significantly disrupted tourism in nearby communities, including Poás, Poasito, Fraijanes, Vara Blanca, and Los Cartagos. Although these areas ...

making sure the pressure and heat below remain trapped Scientists say the stability of the cap likely plays a role in preventing a large volcanic eruption A magma cap that is likely playing a ...

The magma cap is critical for preventing eruptions at Yellowstone. Geoscientists have discovered a magma cap at Yellowstone National Park that is likely playing a critical role in preventing a ...

This magma cap traps heat and pressure, but also allows gas to vent, reducing eruption risk. Seismic imaging and computer models were used to determine the depth and structure of the magma system.
