Workshop on Mechanics of the Earthquake Cycle | (smr 3885) (16-27 October 2023)

Administration

Description

An ICTP meeting in person

This workshop will inform, motivate and provide its participants with the state of the art and current challenges in the mechanics of the earthquake cycle also highlighting the most important areas where significant progress has been achieved recently and the full range of observational, theoretical and technical capabilities now available to the scientific community.

The programme will involve a series of lectures, seminars, discussions, practical and computer exercises.

The workshop will combine analytical and numerical modeling with seismic, geodetic, geologic and laboratory observations, in order to better understand the mechanics of the earthquake cycle. The workshop will focus on both continental and subduction zone earthquake cycles in a viscoleatisc Earth and address the physics of slow and fast earthquake ruptures across multiple scales.
