SEISMIC RISK - OPEN SEMINAR
Welcome to the SEISMIC RISK – Mitigation of induced seismic risk in urban environment – OPEN SEMINAR!

When: Tuesday 11.10.2022 at 9.00–16.00
Where: GTK, Espoo (Vuorimiehentie 5)/Teams
Registration: https://elomake.helsinki.fi/lomakkeet/119238/lomakkeet.html

University of Helsinki, together with the Geological Survey of Finland and VTT, is organizing an Open science seminar on the current activities in geothermal projects and preliminary research results of the Academy-funded SEISMIC RISK – Mitigation of induced seismic risk in urban environment – project.  The hybrid event will take place on Tuesday 11 October at 9-16. Instruction on the remote participation will be sent to registered participants. It will be mainly in Finnish with a few of the scientific presentations in English.

The SEISMIC RISK – Open Seminar consists of scientific introductory presentations in seismic risk, project stakeholder communications, and scientific presentations of the project preliminary results, and discussion on the future tasks and goals of the project.

SEISMIC RISK project is funded through the Academy of Finland's call for new research projects on crisis preparedness and security of supply for 2020-2023 (decision numbers 337913, 338075, 339670).
