For the analysis, Ltd. used data from the European Union’s Copernicus program and the European Space Agency’s Sentinel-1A radar ground observation satellite. researchers – wrote the infostart. This result was obtained by the so-called interferometric comparison of measurements immediately before and after the earthquake. The displacements caused by the Croatian earthquake and permanent surface deformation were probably the first in Hungary, but probably also among the first in the world. The essence of the interferometer method is that a very detailed and accurate map of the displacement can be produced from the phase information of radar measurements in the same area before and after the earthquake.

The earthquake, which is the culmination of a series of earthquakes, struck at noon on December 29, not far from Hungary’s southern border, 50 kilometers southeast of Zagreb. According to the Richter scale, a 6.4 magnitude earthquake could also be felt in Hungary. According to insurers, the amount of domestic damage can reach 100 million HUF.

There have been major earthquakes in the area the day before and since. There is such an earthquake in our area

extremely rare, essentially close to the maximum possible in terms of tectonics and rheology of our immediate surroundings
