7th International Colloquium on Historical Earthqu

Organized by Résif (French seismologic and geodetic network) together with ICGC (cartographic and geological institute of Catalonia), the 7th edition of the International Colloquium on Historical Earthquakes & Paleoseismology studies (ICHEPS-19) will be held from 4 to 6 November, 2019, in Barcelona (Spain).

Knowledge of historical seismicity is fundamental for the comprehension of seismic phenomena as well as for hazard assessment, particularly for regions where damaging earthquakes have long recurrence intervals. In this regard, the study of all data sources giving access to the effects of past earthquakes is essential: while instrumental seismology is “blind” before early/mid XXth century, paleo, archeo and historical approaches allow together to cover centuries of earthquakes through the traces they left in geological formations, buildings and documents.

ICHEPS-19 is titled “Paleo-, archeo-, and historical data of earthquakes: an interdisciplinary discussion of their value and use in seismology”, with three main themes :

1. From the collection to the interpretation of paleo, archeo, and historical data of earthquakes: pitfalls and challenges.
2. From seismological data supplied by paleo-, archeo- and historical studies to earthquake parameters, scenarios, and seismic histories: pitfalls and challenges.
3. An interdisciplinary debate on data representation, levels of data dissemination and accessibility, and treatment of data uncertainties.

We invite you to register as soon as possible and to submit an abstract responding to one of the three themes.

Field trip : November 6, 2019 on the traces of the earthquake of 1427 reference for Catalonia. This excursion in the Amer-Olot region offers a tour of various places of geological and historical interest: destroyed churches, damage to the city of Olot, neotectonic events… guided by ICGC scientists.

Symposium supported by EOST, Seismic Institute, and AXA Insurance.
