Filed under Data analysis, Maps and Records

Data analysis of RAN network records are shown for the May 20th event. Particularly, 6 stations closer to the epicenter (MRN, MDN, NVL, ISD, CPP, ZPP) have been considered. To easily visualize them, the following map could be helpful. For each of the three components – South-North (SN, blue), Est-West...
