Accelerometric Database: Strong-motion recordings (1992–2012) from the PCCI Building, Mexico City

The PCCI (Bernardo Quintana Building) database includes 1,374 accelerometric records obtained from triaxial accelerometers installed at six locations: the sixth floor, third floor, ground floor, free field, and two boreholes at depths of 20 m and 40 m. Each file corresponds to a single acceleration component — longitudinal (L), transverse (T), or vertical (V) — expressed in absolute acceleration units (cm/s² or gal). The data are stored in plain ASCII format, with one file per component, and uniform headers that identify the event and station. The dataset comprises 40 earthquakes that occurred primarily along the Mexican Trench, with magnitudes ranging from Mw 4.6 to 7.9 and epicentral distances ranging from 67 to 531 km.
