Dear colleagues,
We would like to draw your attention to the late-breaking session about the July 29, 2021 M8.2 Chignik, Alaska earthquake at AGU Fall Meeting 2021. The submission deadline for this session is next Tuesday, August 31, 23:59 EDT/03:59 +1 GMT. Authors may submit to this late-breaking session even if they have already submitted the maximum number of first-author abstracts allowed to other sessions.
To submit, login to your AGU User Portal ( https://agu.confex.com/agu/fm21/gateway.cgi? ), select "Late-breaking Sessions" from the left-hand menu, and choose "The 2021 Chignik, Alaska Earthquake".
We look forward to seeing you virtually or in person in December!

Session S028: The 2021 Chignik, Alaska Earthquake.
https://agu.confex.com/agu/fm21/prelim.cgi/Session/126212
Session description:
On July 29, 2021, a M8.2 megathrust earthquake struck offshore the Alaska Peninsula, re-rupturing part of the area that slipped during the 1938 M8.3 earthquake. The Chignik earthquake was the largest event in the US since 1965 and occurred one year after the M7.8 Simeonof earthquake, which ruptured a portion of the Shumagin megathrust segment directly to the west. The sequence of these two earthquakes raises questions about the role of stress loading in triggering the later earthquake and the possibility for further rupture in adjacent regions of the subduction zone. Both earthquakes appear to have ruptured intermediate depths of the megathrust, leaving open questions about slip behavior and earthquake potential at shallower depths. We welcome contributions from geodesy, seismology, geology, and paleoseismology related to the 2020 and 2021 earthquakes and their tectonic context. This may include studies of the individual earthquakes and event triggering, their relationship to geologic structures as well as to the 1938 event or other historic earthquakes, and possible impacts on the surrounding region.
