What we do

The main scope of the IFG Earthquake Geology and Seismic Hazards (IFG EGSHaz) is to increase the understanding of past earthquakes and future seismic risks by investigating the Quaternary geology of seismically active areas. This includes multiple disciplines that contribute to understanding Quaternary earthquake activity, such as palaeoseismology, active tectonics and neotectonic studies, tectonic geomorphology, archaeoseismology, and seismology. IFG EGSHaz promotes interdisciplinary approaches and multi-proxy studies to comprehensively understand the effects that seismic events have on society and on the environment and to improve seismic hazard prediction. This is done in part by co-operation with other IFGs, especially those that work on Quaternary dating methods, Quaternary stratigraphy and soil science, and liaisons with a broader spectrum of Quaternary researchers.

IFG EGSHaz activities are aimed to promote research, education and outreach on the topic of earthquake geology and hazards. One of the IFG's principal aims for the next inter congress period is to establish a worldwide and homogenous database on historical surface ruptures (primary and secondary). This database will become a principal publically available tool for seismic hazard assessment. The other main focus for the IFG during this inter congress period is to develop methods to improve probabilistic approaches to seismic hazard (PSHA) by incorporating active fault data (e.g., slip rates, return periods). The development and evolution of the Environmental Seismic Intensity- ESI 2007 scale helps to assess seismic hazards based on the quantification of earthquake environmental effects.

The main activity of the IFG in 2018 was the 9th PATA Days meeting in Posidi in Greece in June 2018. For 2019 we have two main events:

The four Sessions scheduled for the XX Dublin INQUA Congress are the following:

  • - Earthquake Geology and Seismic Hazards: from Earthquake Mapping of historical and prehistoric earthquakes to paleoseismology
  • - Paleoseismology of plate interiors under Pleistocene climate changes
  • - Subduction zone palaeoseismology
  • - Development of soft-sediment deformation structures (SSDS) and differences between non-seismic and seismic structures
