Webinar – Recent earthquakes in Strasbourg, first lessons learned, Dec. 18, 2020

Following seismic events at the geothermal project in Vendenheim in the Alsace, France in November 2019, that had a magnitude of around 3.1 on the Richter scale, local authorities ordered so-called tracer tests to investigate.

These tests though also are said to have caused seismic events with a magnitude of 1.1. to 2.8 in La Wantzenau north of Strasbourg. Immediately the, tracer tests were stopped. A so-called “safety circulation” continued, however. Nevertheless, the underground did not come to rest. On Friday, December 4, 2020, a seismic event with a magnitude of 3.5 was felt as far as the Ortenau across the border in Germany, followed by another tremor with a magnitude of 2.7. There was no damage to buildings or persons.

Naturally this has caused a lot of speculation and sensationalistic media coverage in France and beyond. To address some of the coverage and discussions surrounding these events, IGC.events is inviting to a webinar on Friday, December 18, 2020 with Prof. Jean Schmittbuhl from EOST – École et Observatoire des Sciences de la Terre – Université de Strasbourg et CNRS (Directeur de CNRS).

Prof. Schmittbuhl has a profound knowledge on the geomechanic and seismology in the Upper Rhine Valley. He will give give an update on what happened in the project and in the subsurface of Vendenheim.
