Description of the data and file structure

The dataset contains 610 observations of hydrological changes associated with 40 seismic events with magnitude ranging between M=4.1 and M=7.1, that have occurred in three areas of Southern Italy (Sannio-Matese, Irpinia-Mefite, Pollino) between 1688 and 2019. We report variations of the discharge of rivers and springs, of the level of the water in wells, effects of liquefaction, turbid flow, and variation of the chemical-physical parameters of waters. The hydrological informations were collected from archives and libraries, coeval chronicles, official reports, newspapers, seismic postcards, macroseismic questionnaires, online databases, and scientific papers.

Description: 

Variables

• Object ID (integer) defines the object identifier
• ID Event (integer) indicates the identifier of the seismic event
• Event date (date) indicates the date of the seismic event in the format yyyy-mm-dd
• Site of observation (text) indicates the name of the site where the hydrological change has been observed
• Site Latitude: double type (three decimal places) indicating the latitude of the observation, in decimal degrees (dd.mmm) within a WGS_1984 Geographic Coordinate System
• Site Longitude: double type (three decimal places) indicating the longitude of the observation point, in decimal degrees (dd.mmm) within a WGS_1984 Geographic Coordinate System
• Site Epicentral Distance: double type (one decimal place) indicating the distance in km between the site of observation and the epicenter of the seismic event
• Hydrological observation: (text) indicates the synthetic description of the reported hydrological effect
• Observation Code: (text) indicates the category of the hydrological effect reported. Seven categories are defined as follows: “L” (liquefaction); “PT” (chemical-physical variation); “R” (river); “S” (spring); “T” (turbid flow); “U” (undefined); “W” (well)
• Quality Code: (text) indicates the quality of the hydrological effect reported. Three categories are defined as follows: “A” (high quality); “B” (intermediate quality); “C” (low quality)
• Notes: (text) provides additional information that characterizes the hydrological observation (time extent, location, rainfall, ecc)
• References: (text) a list of the sources that report the hydrological observation along with a DOI or other stable accession when available
