or objects spewed into the air during eruptions. They can disseminate several kilometers from the source of the eruption, and fatally injure people as well as damage cars, houses, and roads. Hide behind big sturdy rocks or buildings to avoid being hit by cinders. ...
Deep seafloor hydrothermal vent communities buried by volcanic ash from the 2022 Hunga eruptionMass mortality of marine animals due to volcanic ash deposition is present in the fossil record but has rarely been documented in real time. Here, using remotely-operated vehicle video footage and analysis...
Fast forward to 2010, and the eruption of cut-and-paste favourite Eyjafjallajökull in Iceland saw millions of tonnes of ash pumped into the atmosphere and aviation grounded across most of Europe as the significant ash cloud drifted southeast across the Atlantic. Hoey says: ‘What BA9 taught...
Mass mortality of marine animals due to volcanic ash deposition is present in the fossil record but has rarely been documented in real time. Here, using remotely-operated vehicle video footage and analysis of ash collected at the seafloor, we describe th
To the best of our knowledge, this is the first video recording of a phreatic eruption sequence that captures the onset of the eruption and how it evolves to explosive activity at the surface. The unique dataset of proximal geophysical observations and real-time video footage provides us with ...
The Froude number is defined with the peak eruption velocity vp, the gravitational acceleration g, and the still water depth h in the basin. The varied Froude number may represent real world events spanning from slow mud volcanoes to explosive eruptions. More than 300 experimental runs were ...

Some simulations report that the volcano will not become active, while others trend toward mechanical failure within the magma chamber, which can lead to an eruption. The process is very similar to how hurricane predictions are made. “When we do it with hurricanes, we'll see landfall maps...
Play Video Despite the seismic activity in the volcanic region between Sundhnúkur and Grindavík decreasing, the IMO said Monday that the volcanic hazard assessment in the region remains unchanged. So, what do we know about this potential eruption, what are its risks, how could it affect trav...
Moreover, our results show that local electrical monitoring of active volcanoes can provide valuable near real-time information on changes in the explosive eruption style as well as the magnitude, which may pass unobserved by regional and global lightning detection systems. The occurrence of volcanic...
