This project documents an extensive sinkhole collapse that followed the Mw6.4 earthquake in Croatia. The sinkholes collapsed in a small area of two villages, where karstic rock underlays thick clayey sediments. Reconnaissance reports a total of 122 new cover collapse sinkholes within a 1.13 km2 area in twelve months following the MW 6.4 earthquake, described in the GEER report Geotechnical Reconnaissance and Engineering Effects of December 29, 2020, M6.4 Petrinja, Croatia Earthquake, and Associated Seismic Sequence. The project contains spatial and temporal information about sinkholes, and geotechnical investigation works from four boreholes. The audience is geotechnical engineers, geologists, seismologists, and natural hazard professionals.

RTC Lidar for sinkholes, Nanometrics for HVSR ratio, in the area of Mecencani and Borojevici, HVSR in two liquefied fields in Petrinja. Data describes the spatial position of sinkholes, depths, and widths. Four geotechnical boreholes were drilled in the vicinity of the sinkholes. In-situ investigation includes geotechnical classification and Standard Penetration Tests. Laboratory investigation includes index tests, CU, oedometer and SWRC tests.
