Selecting Database

Users, who want to search and download records using SeismoSelect, may choose between five strong motion databases that are available on-line.

NGA-West 2 Ground Motion Database
The NGA West2 Ground Motion Database (Ancheta et al., 2013) has been developed by the Pacific Earthquake Engineering Research Center (PEER), and features a large set of ground motions recorded in worldwide shallow crustal earthquakes in active tectonic regimes. Further info, documentation, crediting, disclaimers, copyright and license terms can be obtained from here and here.

NGA-East Ground Motion Database
The NGA East Ground Motion Database (Goulet et al., 2014) has been developed by the Pacific Earthquake Engineering Research Center (PEER), and features ground motions from events in Central and Eastern North American (CENA) region, including those from an induced and triggered nature. Further info, documentation, crediting, disclaimers, copyright and license terms can be obtained from here and here.

ESM-Engineering Strong-Motion Database 2.0
The Engineering Strong Motion Database (Luzi et al., 2020) has been developed in the framework of the European Project NERA (Network of European Research Infrastructure for Earthquake Risk Assessment and Mitigation), Network Activity 3: Networking acceleration networks and SM data users. The database is maintained by WG5 of ORPHEUS. Further information, documentation crediting, disclaimers, copyright and license terms can be obtained from here.

NGA-Subduction Database
The NGA-Subduction Ground Motion Database (Bozorgnia et al., 2022) has been developed by the Pacific Earthquake Engineering Research Center (PEER), and is the first database to address specifically subduction zones. Further info, documentation, crediting, disclaimers, copyright and license terms can be found in SeismoSelect's help.

New Zealand Ground Motion Database (NZGMDB)
The New Zealand Ground Motion Database (Bozorgnia et al. 2022) has been developed for ground-motion modeling applications of the 2022 National Seismic Hazard Model (NSHM) revision and features ground motions from 5422 events in New Zealand. Further information, documentation crediting, disclaimers, copyright and license terms can be found in SeismoSelect's help.

The selection of the database is done in the Strong Motion Database page of the program. SeismoSelect is then capable of carrying out searches in the flat files of these databases, according to specific user-defined criteria, and subsequently selecting and scaling the records, so that to match the given intensity measures.
