Highlights

  • The Le Teil earthquake occurred near Montélimar in the lower Rhône valley on Monday, 11 November 2019, at 10:52:45 UTC (11:52:45 local time)

  • The collection and analysis of the macroseismic data allowed us to estimate 765 communal values (410 intensities from I to VII–VIII and 355 felt) in the region affected by the Le Teil earthquake

  • While this shift is expected in the epicentral zone for intensities VI and above, it was more surprising at greater distances

Summary

Introduction

The Le Teil earthquake occurred near Montélimar in the lower Rhône valley on Monday, 11 November 2019, at 10:52:45 UTC (11:52:45 local time). 1 Message Formats and Protocols, 1997], the LDG proposes a depth of 2 km, fixed by the analyst At this stage, it is considered with caution because it is estimated with a network whose closest station is located at about 80 km from the epicentre. At 12:16 local time, the BCSFRénass sends an automatic information email to the scientific community, local authorities, the media, and over 1000 subscribers of “franceseisme” mailing list. This email is generated for an earthquake with an LDG alert or that is widely felt. It contains the earthquake location, its magnitude, and a link to the dedicated page on the BCSF-Rénass website (http://www. franceseisme.fr), where testimonies are collected and which contains a lot of automated information (alert message, locations, maps of the effects, preliminary macroseismic intensity map, shakemap, etc.)
