Time-series insights of the geomorphologic changes of the Hunga submarine caldera Open
Caldera volcanoes produce the most impactful eruptions worldwide, yet caldera formation is rarely observed, especially in the submarine environment. We report repeat high-resolution seafloor mapping and quantify the geomorphological change…

Evidence at source for the mid-fifteenth century eruption of Kuwae, Vanuatu Open
The mid-fifteenth century eruption of the Kuwae volcano (Vanuatu), known locally as the Tombuk eruption, is widely but not universally considered responsible for one of the three largest atmospheric sulphate events of the past millennium. …

Morphological evolution of the Hunga Tonga–Hunga Haʻapai submarine volcano after the explosive eruption Open
Submarine eruptions dominate volcanism on Earth, but the recent eruption of Hunga Tonga–Hunga Haʻapai volcano in January 2022 was one of the most explosive eruptions ever recorded. Many large calderas collapse during eruptions a…

Impacts of the mid-15th century eruption at Kuwae caldera, Vanuatu Open
In the AD 1450s, one of the three largest climate-forcing eruptions of the largest 1000 years took place, with similar impacts as the AD 1815 event of Tambora, Indonesia, that caused the ‘year without a summer’ of AD 1816. The …

Post-2015 caldera morphology of the Hunga Tonga-Hunga Ha’apai caldera, Tonga, through drone photogrammetry and summit area bathymetry Open
<p>In December 2014, eruptions began from a submarine vent between the islands of Hunga Tonga and Hunga Ha&#8217;apai, 65 km north of Tongatapu, Tonga. The &#8220;Hungas&#8221; represent small NW and NE remnants of the fl…
