Thanushika Gunatilake

Hello Thanushika – welcome to GeoTalk! Before we delve deeper, could you introduce yourself to our readers? Thank you for having me! I’m Thanushika Gunatilake, an Assistant Professor at Vrije Universiteit Amsterdam. My research connects natural and human-induced processes in the Earth’s crust; from earthquake nucleation in the central Apennines, subduction dynamics, and volcanic activity, to geoth ...[Read More]

The spectral shadow of Samalas: When climate models conjure the Earth’s forgotten fury

Rinjani Volcano (3726m, Lombok Island, Indonesia) in eruption. A lava flow is emitted on the flank of the intra caldera cone of Gunung Baru. Mild explosive activity at the vent is producing a 1500m high gas and ash plume, while a viscous lava is entering the 200m deep caldera lake. A hot spring on its shower release a plume of iron hydroxide precipitates giving a peculiar yellow color. Source: Imaggeo

This Halloween, we turn our gaze from fictional haunts to the chilling, rigorous world of paleoclimatology. The paper by Hartmann et al. (2025), published on Climate of the Past, focuses on the implementation of external forcings in a regional climate model around the 1257 CE Samalas volcanic eruption. This paper can be quite the unsettling investigation, since it treats the Earth itself as a time ...[Read More]

Sarakiniko, a stunning geological landmark on the aegean island of Milos, Greece, is under imminent threat. Known for its breath-taking white tuff formations built by the deposition of submarine volcanic eruptions and sculpted by wind and water over millions of years, this site serves as both a natural laboratory for geoscience and planetary research and a worldwide significant geoheritage site. H ...[Read More]
