ESM, the Engineering Strong-Motion Database, provides a set of facilities to search, select, download and analyse ground-motion data and associated metadata. The waveforms contained in ESM are relative to events with magnitude ≥ 4.0, mainly recorded in the European-Mediterranean regions and the Middle-East. ESM is targeted to applied seismologists, earthquake engineers, professional engineers, geologists and policy makers.
July 2025: data from some temporary stations that were previously assigned to the IV network have now been reassigned to new temporary network codes. The updated network codes are: 8P, 9K, 5G, 9N, 3H, 2J, 8H, 5H, and 2D. The database has been updated accordingly, based on the operational periods of each network as provided by the FDSN.
