Abstract

The European-Mediterranean Seismological Centre (EMSC) is a non-profit scientific organization aiming at establishing and operating a rapid earthquake detection system globally and in particular in the European and Mediterranean regions as well as facilitating exchange between seismological institutes. The EMSC has been a pioneer in citizen seismology by collecting in-situ information on the earthquake impact directly from the witnesses.

The EMSC has been collecting citizen intensity felt reports at a global scale for many years via two channels: its websites and its “LastQuake” smartphone application. These felt reports are collected through a set of 12 cartoons representing the 12 levels of the European Macroseismic Scale (Grünthal, 1998). They provide rapid information on how the earthquake’s impact is felt by the local population. The EMSC felt reports were shown to be consistent with the USGS Did You Feel It? (Wald et al., 2011) responses and with manually derived macroseismic datasets (Bossu et al., 2016).

This dataset includes four ".csv" files in total. The file, "felt_reports_2014_2021.csv" and "catalog_2014_2021.csv" contain an exhaustive set of globally collected felt reports between January 2014 and December 2021, and the corresponding earthquake catalog, respectively. The files "felt_reports_2022.csv" and "catalog_2022.csv" contain felt reports for a selection of 11 well reported earthquakes from 2022 and the corresponding earthquake catalog, respectively. This data is the foundation of the work by Lilienkamp et al. (2023).
