EMS98 intensities distribution of the “Le Teil” earthquake, France, 11 November 2019 (Mw 4.9) based on macroseismic surveys and field investigations

Abstract : The Le Teil earthquake (south France, 11-11-2019, Mw 4.9, 1 km depth, about 4 km of surface ruptures) was felt at a distance up to about 300 km. In order to estimate the EMS98 intensity in each of the affected localities, we collected macroseismic observations via individual forms filled in by citizens (2094 testimonies) or collective forms filled by authorities (388 localities) and by field survey work in the epicentral zone (24 most damaged cities). Field observations and communal surveys remain essential in the case of structural damage. Intensities deduced from public surveys are preliminary and their consideration in the final estimates must be limited. The maximum intensity observed is VII-VIII in Le Teil and 30 localities experienced an intensity ≥ VI. The earthquake generated damage (I ≥ V) up to about 50 km away and was felt in at least 568 localities.
