Local Seismic Cultural Noise data of National Capital Region, India

Local Seismic Noise waveforms recorded by the Seismic Sensing Nodes, developed by CSIR-Central Scientific Instruments Organisation (CSIR-CSIO, Chandigarh, India), placed in five locations of NCR, India from Oct'14 - Feb'19 are collected. This database contains 38030 tri-axial seismic noise accelerograms and corresponding metadata. The metadata and raw waveform data are stored in a BSON formatted files titled header.bson and accelerogram.bson respectively.

Each accelerogram record contains header information regarding Peak Ground Acceleration ( tri-axial PGA) at the sensor site. Some of the local noise records also contain signals generated due to strong distant earthquakes or insignificant local tremors from nearby fault regions. These records are significantly less in number and recorded partially in separate event files. Hence, due to the unconfirmed nature of sources, these files are included in this local noise dataset.

本数据集收录了由印度加尔各答中央科学仪器组织（CSIR-Central Scientific Instruments Organisation，简称CSIR-CSIO，位于印度昌迪加尔）研发的地震感知节点在2014年10月至2019年2月期间，于印度国家首都区域（NCR）的五个地点所采集的局部地震噪声波形。该数据库包含38030个三轴地震噪声加速度计记录及其相应的元数据。元数据和原始波形数据分别以BSON格式存储，文件名称分别为header.bson和accelerogram.bson。每个加速度计记录中包含了关于传感器站点峰值地面加速度（三轴PGA）的头部信息。部分局部噪声记录还包含了由强烈远距离地震或附近断层区域微弱地震引起的信号。这些记录数量较少，并部分记录在单独的事件文件中。由于这些文件来源的不确定性，因此这些文件也被纳入了本局部噪声数据集中。
