When glaciers melt and permafrost thaws, meltwater finds new pathways into the deep underground. Shallow earthquakes are related to runoff from the previous year, and deeper earthquakes to runoff from the year before that.

Glacier melt increases seismic activity under the Mont Blanc Massif

There have been repeated small earthquakes under and around the Mont Blanc Massif for around ten years now. A new study demonstrates for the first time a link between climate-driven changes in glaciated high mountain regions and increased local earthquake hazard. ...

SED monitoring test stimulations for Haute-Sorne geothermal project (canton of Jura)

On Friday, 13 June, the canton of Jura granted approval for test stimulations as part of the geothermal project in Haute-Sorne (JU). These tests will involve forcing pressurised water into the geological underground through the exploratory borehole which was drilled in summer 2024. The water will emerge around four kilometres below the surface before filtering into the adjacent rock. The test stimulations are intended to trigger many minor earthquakes far below the sensitivity threshold. ...
