Ongoing Activity at Hunga Submarine Volcano, Tonga: The Case for Better Monitoring of Submarine Volcanoes Worldwide

open access: yesGeochemistry, Geophysics, Geosystems
AbstractThe powerful eruption of Hunga volcano (15‐January‐2022) excavated ∼6.3 km3 of pre‐existing material, leaving behind an 855 m deep crater. The scientific and humanitarian response to this event was challenging due to the remote location, safety concerns, and COVID‐19 pandemic restrictions.

Volcano-tectonic evolution of the polygenetic Kolumbo submarine volcano/Santorini (Aegean Sea)

open access: yesJournal of Volcanology and Geothermal Research, 2015
Abstract Here we show for the first time the 3D-structural evolution of an explosive submarine volcano by means of reflection seismic interpretation. Four to five vertically stacked circular and cone-shaped units consisting mainly of volcaniclastics build the Kolumbo underwater volcano which experienced its first eruption > 70 ka ago and its last ...

HUNGA-TONGA-HUNGA-HA’PAI VOLCANIC ERUPTION/EXPLOSION AND TSUNAMIS OF 14-15 JANUARY 2022 – Overview and Analysis [PDF]

open access: yesScience of Tsunami Hazards, 2022
The explosive eruption/collapse of the submarine portion of the volcano Hunga-Tonga- Hunga-Ha'apai (HT-HH) on the Tonga Kermadec volcanic arc in the southwest Pacific on 15 January 2022 occurred at the end of many weeks of activity. It was a truly global

Ocean bottom tiltmeter developed for submarine volcano monitoring

open access: yesEos, Transactions American Geophysical Union, 1991
Most of the oceanic crust is formed by intrusive processes, yet these processes at mid‐ocean ridges are poorly understood when compared to on‐land volcanos that are well monitored with respect to their surface deformation and seismic activity. This limited knowledge of tectonic processes at mid‐ocean ridges stems from an absence of direct observations ...
