RAPID SEISMIC INTENSITY ASSESSMENT IN ROMANIA USING INTERNET MACROSEISMOLOGY
Abstract
Romania is one of the most seismic-prone countries in Europe due to the periodically occurrence of strong intermediate-depth earthquakes in Vrancea seismogenic zone. In the last decades, many efforts were done to gather macroseismic intensities in case of felt Vrancea earthquakes and additionally an online environment was developed for the automatic approximation of the intensity from people feedback. Besides the extended scientific studies, the near real time estimation of the macroseismic intensity recently became mandatory for the insurance companies to cover some of the losses and damage that earthquakes might cause to houses, belongings, and other buildings. The procedure proposed in this paper for rapid macroseismic estimation and loss assessment for the recent intermediate-depth Vrancea earthquakes with MW>4.5 is using the online macroseismic questionnaires, and the automatic intensity estimation code recently improved. Besides the automatic estimation, we have also used the classical approach to assess the intensity data points and also the available equations for conversion of peak ground acceleration in macroseismic intensity (including de Romanian Macroseismic Intensity Standard).
