Abstract

Regional shaking map tool for rapid characterization of the strong ground motion following the significant earthquake has been developed. New tool is based on state-of-the-art data processing technologies and regional seismological data. The earthquake data processing system uses regional and global seismic stations. The technologies for generating shaking maps is mostly automatic. Public information on recent and past earthquakes is freely available on the eqalert.ru website. Internet users can also submit the felt report through the eqalert.ru using “Did you feel the earthquake?” questioner, unified in accordance with the U.S. Geological Survey DYFI. Automatic earthquake notification is freely available in the form of PUSH-notification for Android and iOS mobile applications and Telegram messenger bot.

Highlights

  • The main goal of shaking map is to produce near-real time maps of ground shaking following significant earthquakes

  • The felt reports of the respondents from each settlement was transformed to Community Weighted Sum (CWS) with the calculation of the Community Decimal Intensity (CDI) using equation [16, 17]: CDI = 3.4 ln (CWS) – 4.38

  • We have developed regional shaking map tool for rapidly characterizing the parameters of strong ground shaking following the significant earthquake

Summary

Introduction

The main goal of shaking map is to produce near-real time maps of ground shaking (peak ground acceleration, response spectra, seismic intensity etc.) following significant earthquakes. The most popular shaking map product is ShakeMap [1], developed by U.S Geological Survey. It facilitates communication of earthquake information beyond just magnitude and location of the source. Shaking map is a tool for emergency response, public information, loss estimation and post-earthquake engineering and scientific analyses. It is actively used by the government, emergency surveys, industrial companies and scientific community. The main goal of our research is to develop the regional shaking map product (EQA!ert Project [2]) based on new data processing technologies, state-of-art methods of earthquake notification, regional earthquake information and recent geological data
