The Climate and Geological Environment Survey Dataset along the Belt and Road consists of five parts: seismic and geological hazard event dataset, flood disaster event dataset, meteorological disaster raster dataset, groundwater change trend raster dataset, and geological hazard event records and seismic event case sets along the Jakarta-Bandung High-Speed Railway and China-Pakistan Railway. Specifically, the seismic and geological hazard event dataset covers the locations of active faults, records of earthquakes with magnitude ≥5.5 from 1950 to 2020, and records of landslide, debris flow and collapse disasters from 2007 to 2020. The flood disaster event dataset contains historical flood disaster event records from 1985 to 2016. The meteorological disaster raster dataset includes extreme values of various meteorological elements extracted from historical records between 1979 and 2020, with specific elements including freezing index, annual frequency of freeze-thaw cycles, annual number of high-temperature days, annual number of rainstorm days, annual temperature difference, total annual precipitation, maximum daily precipitation, average daily wind speed, daily solar radiation, daily temperature difference, relative humidity, minimum temperature, and maximum temperature. The groundwater change trend raster dataset provides change trend data from 2003 to 2016. The geological hazard event records and seismic event case sets along the two railways include geological hazard event records and seismic event records along the Jakarta-Bandung High-Speed Railway and China-Pakistan Railway. Taking ten earthquakes along the China-Pakistan Railway as examples, hourly temperature data within the two months closest to each earthquake's occurrence date is extracted, with records taken every two hours. All data were processed using general-purpose computer equipment and basic data processing methods. The data used in this study were all curated and preprocessed by professional institutions. Specifically, the active fault data is sourced from "The GEM Global Active Faults Database" released by the Global Earthquake Model (GEM); historical earthquake record data comes from the United States Geological Survey (USGS); historical geological hazard datasets are from the National Aeronautics and Space Administration (NASA); historical flood disaster datasets are derived from the open dataset of the University of Colorado; meteorological data is sourced from the European Copernicus Climate Change Service Climate Database; groundwater data is from GRACE gravity satellite remote sensing data processed by NASA.
