When QuakeManager is installed, it installs a ground motion library folder on your disk, and during the installation it will ask you to confirm the location for that folder. By default, this folder is C:\GMLibrary\, and the following are the files and folder that will be installed in the GMLibrary folder:
•File: QMDB.db -> This is the actual ground motion database file where the metadata for all records is stored. Note that the database does not include the actual recorded acceleration histories, it only includes metadata about the records, including information about the earthquake event, the recording station, the processing of the record, and so on. It also includes more than 30 different intensity measures including PGA, PGV, PGD, etc and spectral values, all of which are valuable to have in the database when you are searching and filtering and trying to find the best candidates for your ground motion selection, scaling and modification.
•Folder: SACSteel -> This is where the all SACSteel ground motion recorded acceleration files are installed by QuakeManager. If you go into the sub-folders (e.g. LA 10 in 50), you will see ground motion acceleration files each representing one component of a record. If you open one of them, you will see that this is the actual ground motion acceleration data.
•Folder: NGA-West2 -> QuakeManager installs this empty folder for the NGA-West2 ground motions. This is a placeholder folder for storing NGA2 ground motion files that can be downloaded from the PEER NGA website. All downloaded NGA records go in the same folder, which makes them easier to manage.
•Folder: NGA-Sub -> QuakeManager installs this empty folder for the NGA-Sub ground motions. This is a placeholder folder for storing NGA subduction ground motion files that can be downloaded from the UCLA Risk Science website. All downloaded records go in the same folder, which makes them easier to manage.
•Folder: AFAD Türkiye Feb2023 Records -> QuakeManager installs this empty folder for the February 2023 Turkish ground motions. This is a placeholder folder for storing turkish ground motion files that can be downloaded from the AFAD-TADAS website. All downloaded records go in the same folder, which makes them easier to manage.
