International Workshop on Active Tectonics and Seismicity of the Aegean Region with Special Emphasis on the Samos Earthquake struck on 30 October 2020 - ASASE2021





The ASASE2021 will be held from May 20 to 21, 2021 and will be organized online due to the COVID-19 pandemic. It is dedicated to the discussion of the earthquake phenomena considering the effects of Samos Earthquake struck on 30 October 2020 and to shed light on the active tectonics and seismicity of the Aegean Region.

About ASASE2021

Active Tectonics and Seismicity of the Aegean Region with special emphasis on the 30 October 2020 Samos Earthquake (ASASE2021) will consist of oral and poster presentations of the invited speakers. The workshop will cover a wide range of topics related to earthquake studies, such as active tectonics, geodynamics, seismic, tsunami, Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) applications. Due to the COVID-19 pandemic, the workshop will only include video conference sessions. We welcome participants from all over the World!
