of lava into the air. In more violent eruptions, the magmaconduitis hollowed out by an explosive blast, and solid fragments are ejected in a great cloud of ash-laden gas that rises tens of thousands of metres into the air. An example of this phenomenon is the 1980 eruption ofMount Saint...
The 1969 eruption at Mauna Ulu, a vent of Kilauea Volcano in Hawaii, was a spectacular example of fire fountaining. Photo by D.A. Swanson, USGS, August 22, 1969. Enlarge Image ADVERTISEMENT Volcanic Eruptions The most common type of volcanic eruption occurs when magma (the term for lava ...
The magnitude, style, and sometimes-prolonged nature of volcanic activity in Alaska has had significant impact on ecological habitat. The accumulation of volcaniclastic deposits during eruptions have destroyed or altered areas important to the success of various species and it may take years to decades...

Volcanic eruptions are an imperfect analog, since solar radiation management proposals involve the production of a permanent stratospheric aerosol layer, while volcanic layers are episodic. Nonetheless, we can learn much from the volcanic example about the microphysics of stratospheric sulfate aerosol ...

The combined workflow now allows us to illuminate potentially the most interesting, and certainly most obscure, parts of the volcanic seismic cycle. 1 Introduction The rupture of rocks, as manifested by earthquakes, is an intrinsic part of volcanic eruptions. The seismic waves of earthquakes are ...

The paper examines independent pyroclastic ejections of cumulates, followed by powerful eruptions of pyroclastic material, using the example of allivalite (olivine-anorthite) segregations. It is shown that the bulk density of the allivalite segregations is 0.1-0.4 g/cm lower than that of the hos...
Volcanic eruptions are typically preceded by unrest, marked by increased seismicity, ground deformation, and gas emissions. Unrest can last from decades to minutes. Accurate eruption forecasting relies on real-time monitoring and understanding the volcano’s past behavior. Long-term hazard assessments, ...
