All the earthquake that took place after 2004 are distributed in the Romania counties. Earthquakes were split in two categories: with power below 4 Richter (Power <= 4), and with power above 4 Richter (Power > 4). Each category is in one Tableau worksheet, where the number of earthquakes for each county are displayed on the map, inside the county. The distribution is also done in the historical regions of Romania, in another worksheet (Regions: power <= 4).
The raw data with earthquakes was taken from The Romanian National Institute for Earth Physics: Romanian earthquakes data until 30.06.2022
