Tsunamis and pyroclastic density currents over water during the 1815 Plinian eruption of Tambora, Indonesia - Bulletin of Volcanology Plinian eruptions located near the sea or a lake are likely to generate pyroclastic density currents (PDCs) that trigger tsunamis and propagate on the water surface, thereby widening the range of haza...

Researchers of the LMV studied tsunami deposits and pyroclastic flow deposits from the iconic Tambora eruption in 1815. Field work was supplemented by experiments in an experimental flume. Paper published in Bulletin of Volcanology : doi.org/10.1007/s004...

🌋 Eruption en cours au Piton de la Fournaise

Suite à la crise sismique débutée à 09h25 heure locale le 13 février 2026, le trémor volcanique est enregistré depuis 10h00 environ heure locale.
Les fissure(s) éruptives se sont ouvertes proche du sommet au flanc sud du volcan.

Alerte 2-1

Et si les volcans du Massif central se réveillaient ? Dans l’imaginaire collectif, nous avons tendance à penser que les volcans d’Auvergne sont éteints. Pourtant de nombreux signes montrent qu’ils sont potentiellement actifs.

Shear-induced bubble nucleation in magmas The nucleation of gas bubbles in magmas is fundamental to controlling the dynamics of volcanic eruptions. In this study, we addressed nucleation in a volatile-saturated liquid triggered by viscous she...

Submarine ash megabed fed by far-traveled, shoreline-crossing pyroclastic currents from a large explosive volcanic eruption Volcanic ash from an eruption in Greece poured into the sea, forming a bed 200 m thick in a submarine basin far from the volcano.

A new publication on the study of the physical and textural parameters of tephras that has enabled us to propose a model explaining the sequence of events during the last eruption of the Chaîne des Puys.
