Socio-economic activities in a territory entail an environmental impact on the ecosystems.
This impact is usually negative on the land and biodiversity since food production replaces …

In this first detailed study of zircon from Ascension Island, South Atlantic, we take a novel
approach combining trace element and O isotope compositional data with double-dating …

Explosive eruptions of trachytic to trachyandesitic composition produced thick and
widespread pyroclastic deposits during the recent volcanic activity of Piton des Neiges …

Many intraplate oceanic islands undergo “rejuvenated” volcanism following the main edifice-
building stage. Honolulu features Hawai 'i's most recent rejuvenated volcanism. K-Ar dating …

Tephra fall can lead to significant additional loading on roofs. Understanding the relevant
geomechanical properties of tephra is critical when assessing the vulnerability of buildings …

Proximal deposits of small-volume trachytic eruptions are an under-studied record of
eruption dynamics despite being common across a range of settings. The 59±4 ka Echo …

Proximal to the source, tephra fall can cause severe disruption, and populations of small
volcanically active islands can be particularly susceptible. Volcanic hazard assessments …

We present a petrologic study of the ca. 110 ka Halarauður eruption (7±6 km3 magma),
associated with collapse of Krafla caldera in northeast Iceland. Whole-rock compositions of …

Pumiceous deposits, commonly found in volcanic regions such as the Ring of Fire and the
Alpide Belt, pose significant engineering challenges due to the presence of highly crushable …
