The distribution of invasive plant species of concern in the Kīlauea and Mauna Loa strip areas of Hawai‘i Volcanoes National Park, 2000-2010 [PDF]
Reports were scanned in black and white at a resolution of 600 dots per inch and were converted to text using Adobe Paper Capture Plug-in.Alien plant surveys conducted between 2000 and 2010 in Hawai‘i Volcanoes National Park quantified the distribution ...

Partitioning of light lithophile elements during basalt eruptions on Earth and application to Martian shergottites [PDF]
An enigmatic record of light lithophile element (LLE) zoning in pyroxenes in basaltic shergottite meteorites, whereby LLE concentrations decrease dramatically from the cores to the rims, has been interpreted as being due to partitioning of LLE into a ...

Thallium Isotopic Compositions in Hawaiian Lavas: Evidence for Recycled Materials on the Kea Side of the Hawaiian Mantle Plume [PDF]
Hawaiian volcanoes record 6 Ma of potentially deep mantle chemistry and form two parallel volcanic chains that are geochemically unique, named Loa and Kea.

Abstract Abrupt transitions in eruptive style are common at mafic volcanoes, possibly leading to styles that potentially damage infrastructures and threaten the surrounding communities. During the 19th September–13th December 2021 Cumbre Vieja eruption (La Palma, Canary Islands), rapid changes in eruptive style were observed, from vigorous lava ...

The Birth of a Hawaiian Fissure Eruption [PDF]
Most basaltic explosive eruptions intensify abruptly, allowing little time to document processes at the start of eruption. One opportunity came with the initiation of activity from fissure 8 (F8) during the 2018 eruption on the lower East Rift Zone of ...

Abstract Volcanic edifices are known to be unstable and their collapses have been observed several times in history. A collapse of island or coastal volcanoes is especially hazardous for the population living on regional shorelines due to the generation of destructive tsunami waves.

Effects of Regional Stress State and Pore Fluid Pressure on the Onset and Style of Caldera Collapse
Abstract Collapse calderas result from subsidence of a magma reservoir roof during large‐volume eruptions. Whilst calderas form in various tectonic settings, it is unclear how regional (“far‐field”) forces influence caldera fault nucleation, orientation and architecture.

Abstract Morphological scaling laws for basaltic lava flows, linking flow dimensions and eruption conditions, are essential for hazard assessment and geological analysis of basaltic eruptions. However, the governing factors influencing flow dimensions remain unclear.
