Strain-induced magma fragmentation in explosive eruptions
Nature, 1999Explosive eruptions are the most powerful and destructive type of volcanic activity. These eruptions are characterized by magma fragmentation, the process through which a bubbly or foamy magma is transformed into a gas-pyroclast dispersion. Although magma fragmentation has been investigated both experimentally and theoretically, and the basic transport

Tephra from the 1979 Soufriere Explosive Eruption
Science, 1982The explosive phase of the 1979 Soufriere eruption produced 37.5 × 10 6 cubic meters (dense-rock equivalent) of tephra, consisting of about 40 percent juvenile basaltic andesite and 60 percent of a nonjuvenile component derived from the fragmentation of the 1971-1972 lava island during phreatomagmatic explosions ...

Can climate crisis evoke explosive eruptions?
2022<p>Phreatic events are the most unpredictable forms of volcanic activity. These explosive eruptions result from hydrofracturing of the host rock when the pressure of subsurface fluids exceeds the failure threshold. Fluid pressures may be sufficiently increased by an adjacent magmatic heat source, by topographically driven hydrostatic head,

Explosive and Eruptive Variable Stars
2018The breadth of activity among variable stars is almost overwhelming, and the possibilities of observing them seem almost endless. Many variables are followed by observers for their relatively slow pace of decline and recovery and enable one to gauge smooth light curves and collect data for a number of years.

The dynamics of explosive volcanic eruptions
Reviews of Geophysics, 1995Explosive volcanic eruptions involve the ejection of dense mixtures of ash and gas from a volcanic vent at high speed and pressure. This mixture is generated as liquid magma rises from a crustal magma chamber and decompresses, exsolving water vapor. As gas is exsolved, the mixture inflates, accelerates, and becomes foam‐like.
