Surface-to-space atmospheric waves from Hunga Tonga–Hunga Ha’apai eruption
Nature, 2022 The January 2022 Hunga Tonga–Hunga Ha’apai eruption was one of the most explosive volcanic events of the modern era1,2, producing a vertical plume that peaked more than 50 km above the Earth3.

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]
, 2012 Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

Temporal variations of magma composition, eruption style and rate at Fuji Volcano, Japan
Earth, Planets and Space, 2021 Mt. Fuji is an active basaltic volcano near the Tokyo metropolitan area; future eruptions could thus have serious nationwide impacts. To better understand recent volcanism at Fuji Volcano, we here clarify temporal variations of eruption rate and magma ...

Diverse tsunamigenesis triggered by the Hunga Tonga-Hunga Ha’apai eruption
Nature, 2022 On the evening of 15 January 2022, the Hunga Tonga-Hunga Ha’apai volcano1 unleashed a violent underwater eruption, blanketing the surrounding land masses in ash and debris2,3. The eruption generated tsunamis observed around the world.

Explosive Behavior of Intermediate Magmas: The Example of Cotopaxi Volcano (Ecuador)
Geochemistry, Geophysics, Geosystems, 2021 The variability in intensity and style shown by explosive volcanism has been traditionally explained by a complex interplay among melt composition and pre‐eruptive volatile content, which modulate magma ascent and conduit dynamics. However, magmas having

Magma reservoir growth and ground deformation preceding the 79 CE Plinian eruption of Vesuvius
Communications Earth & Environment, 2023 The 79 CE eruption of Vesuvius is the first documented Plinian eruption, also famous for the archaeological ruins of Pompeii and Herculaneum. Although much is known regarding the eruption dynamics and magma reservoir, little is known about the reservoir ...

Quiet Sun Explosive Events: Jets, Splashes, and Eruptions
, 2012 Explosive events are small transition region phenomena characterised by broad non-Gaussian wings in their line profiles. Images from the Solar Dynamics Observatory (SDO) give a first view of the plasma dynamics at the sites of explosive events seen in O ...

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano reached the mesosphere
Science, 2022 Explosive volcanic eruptions can loft ash, gases, and water into the stratosphere, which affects both human activities and the climate. Using geostationary satellite images of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, we find
