Data Set of selected strong motion parameters and Fourier Amplitude Spectra for the East Anatolian Fault Zone, Türkiye (January 2019 - February 2024)

This product represents a high-quality Data Set useful for seismological studies in the East Anatolian Fault Zone, Türkiye and is addressed to the community that study the seismic source and ground motion.

The dataset considers 9,442 events in a magnitude range Ml from 2.0 to 5.5. The period covered by the dataset includes seismicity between January 1, 2019 and February 29, 2024 for a total of 270,704 seismic phases (148,223 P and 122,481 S). In addition to the earthquake catalog, the dataset includes selected strong motion parameters such as selected Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), as well as Fourier Amplitude Spectra (FAS).

The dataset is distributed through the following tables, which are descrived in the "Table of contents" below.

events_catalog.csv is the file of earthquake;

stations.csv is the file of stations;

PGA_PGV.csv is the file of PGA and PGV;

FAS.tar.gz is the folder which contains (in .csv format) the 98 FAS from 0.05 to 47.20 Hz.

For more details on this dataset, have a look at our manuscript "A high-quality Data Set for seismological studies in the East Anatolian Fault Zone, Türkiye ” submitted in Earth System Science Data (ESSD) journal.

本数据集为土耳其东安纳托利亚断裂带的地震学研究提供高质量支撑，面向地震震源与地面运动研究领域的科研群体。

本数据集收录2019年1月1日至2024年2月29日期间的地震活动数据，共计9442次局部震级（Ml）介于2.0至5.5之间的地震事件，总地震震相数量达270704个，其中P波震相148223个，S波震相122481个。除地震目录外，数据集还包含精选的强运动参数，包括峰值地面加速度（Peak Ground Acceleration, PGA）、峰值地面速度（Peak Ground Velocity, PGV）以及傅里叶振幅谱（Fourier Amplitude Spectra, FAS）。

本数据集通过以下文件分发，具体说明详见下文“目录”部分：

events_catalog.csv：地震事件目录文件；
stations.csv：台站信息文件；
PGA_PGV.csv：峰值地面加速度与峰值地面速度参数文件；
FAS.tar.gz：包含98组傅里叶振幅谱数据的压缩文件夹，频谱范围覆盖0.05 Hz至47.20 Hz，所有数据以.csv格式存储。
