Kymenlaakso Seismic Experiment – KySe 2026

The motivation for the project is to better understand offshore earthquakes in the rapakivi region and to learn more about existing fault systems using seismic imaging techniques. 

The deployment will run between May and September 2026 and include 20-30 Güralp 3ESPC 3-component broadband seismometers from FINNSIP (). The instruments will be installed on exposed bedrock to ensure good coupling. Existing power and infrastructure will be used where possible and solar panels and batteries where needed. The instruments will be protected from rain and wind noise will be minimized. The temporary network will include both single seismometer installations and small arrays. The network will include both offline and online stations to enable the use of the data in daily seismic analysis. 

The deployment is expected to improve the detection of small earthquakes in the region which may not be easily detected or located using the existing permanent seismic network. The temporary network will function as a test of whether new permanent seismic stations in the area would provide a benefit to the detection of earthquakes and explosions in southeastern Finland. The experiment will provide a useful insight into seismic risk in the coastal rapakivi environment.
