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.

PCCI数据库（伯纳多·金塔纳大楼，Bernardo Quintana Building）包含1374条加速度记录，这些记录由安装在6个监测点位的三轴加速度计（triaxial accelerometers）采集得到：6楼、3楼、地面层、自由场场地（free field），以及2个深度分别为20米与40米的钻孔。每个文件对应单个加速度分量——纵向（L）、横向（T）或竖向（V），以绝对加速度单位（cm/s²或伽（gal））表示。数据以纯ASCII格式（plain ASCII format）存储，每个分量对应一个独立文件，且带有统一的文件头，用于标识对应地震事件与监测台站。该数据集涵盖40次地震，这些地震主要发生于墨西哥海沟（Mexican Trench）沿线，震级范围为矩震级（Mw）4.6至7.9，震中距（epicentral distances）范围为67至531千米。
