Seismic hazard assessment in regions of low lithospheric strain rely on a global-analogues approach for parameterizing seismic hazard models. In this approach, seismicity rate and earthquake recurrence distributions are generated by amalgamating aerial source zones with limited seismicity data or by drawing on more far‐field analogue regions of slow lithospheric strain. The premise is that regions of low lithospheric strain have the same seismogenic potential. This session seeks to discuss new insights into this premise.
We invite contributions that (1) present new observations that place constraints on earthquake occurrence in low-strain regions, (2) explore patterns of stable or temporally varying earthquake occurrence, and (3) provide insight into the mechanisms that control earthquakes in regions of slow deformation via observation and/or modeling.
These contributions cover two different research components. The first component calls upon researchers with recently developed paleoseismic, geomorphic, geodetic, geophysical, and seismologic datasets that provide insight into the earthquake cycle in low-strain settings. The second component includes contributions that more broadly synthesize recent insights into the seismotectonics of low strain regions and/or explore the driving mechanisms for earthquakes in these regions. Collectively, these contributions provide a current view of the global-analogues premise.

How to access NH4.5
Session NH4.5 runs as a vPICO session. Everybody, conveners/chair/speakers as well as attendees, join the live session page on EGU21. While attendees stay on this live session page and see the live presentations via stream, you as convener/chair/speaker are required to enter the BigBlueButton (BBB) live video chat to give your presentation.
Please keep the live session page open on this browser tab and join the BBB video chat in parallel on another browser tab through the button below. Your personal breakout text chat following the live presentations are linked from the live session page tab, not from the additional BBB video chat tab.Enter BBB video chat
