Dr. sc. Alen Berta, a forestry engineer and executive consultant at the international consulting company CGI in charge of Earth observation, posted on his Facebook profile satellite images showing the full extent of the disaster that struck the Banovina area.
Satelitske snimke svjedoče o razmjeru katastrofe izazvane potresom: Tlo Petrinje spustilo se za više od 10 cm
„Petrinja earthquake
Satellites show the full scale of the disaster. Comparing the images of the Sentinel 1 radar satellite from 18.12. and 30.12. we see that the ground west of Petrinja moved towards the satellite by 44 cm in the most pronounced part, while the ground of Petrinja itself dropped by 10 to 30 cm. These areas have a radius of 10 km. However, in the belt surrounded by the line Popovača, Sunja, Kostajnica, Dvor, we also notice a shift of a few centimeters, which was still fatal for many houses damaged by war and time.
This amount of ground movement is larger than during the devastating earthquakes that occurred in Italy 3-4 years ago. Just to remind that in the Zagreb earthquake, the ground moved only a few centimeters in the epicenter, while in the City itself it was a few millimeters.“
And yesterday morning there was one minor earthquake of magnitude 2.0 less than 10 km away from us:
Earthquake, Magnitude 2.0 - CROATIA - 2020 December 31, 07:51:29 UTC
I have been following earthquake reports for several years, and such minor earthquakes in the area near me occur relatively often, at least several times a year. I hope they really aren’t an introduction to something bigger.
