• Furthermore, to avoid the association with wrong events, we filter testimonies in distance and in intensity depending on the magnitude of the seismic event.
• (*) The "Main city" in the table above is estimated using the cities1000 data from geonames.org. The "-" means that no city is found in this database.

ShakeMap-EU is a collaborative initiative that provides rapid maps of ground shaking service for earthquakes in the Euro-Mediterranean area by integrating data from EPOS services. The earthquake location and magnitude are sourced from EMSC, while the ground motion data come from ORFEUS and the ground motion models are taken from EFEHR and national configurations. ShakeMapEU generates maps for earthquakes with M ≥ 4.0, provided ground motion recordings are available.

The maps help visualise the distribution and intensity of ground shaking, supporting scientific research, emergency response, and risk assessment. ShakeMap-EU aims to enhance accessibility and interoperability within the EPOS framework.
