Dear members of the community,
We would like to draw your attention to a newly announced late-breaking
session at the AGU Fall Meeting 2021!
The August 2021 South Sandwich Islands earthquake sequence: What
happened, regional tectonic context, and potential for South Atlantic
On August 12, 2021 a complex earthquake sequence occurred beneath the
South Sandwich Islands along the Scotia Arc. Magnitude estimates for the
two (or more?) possibly slow ruptures are still under debate, though
most estimates suggest that at least one event in this doublet was a
great earthquake (M8+). Additionally, this sequence generated a
far-reaching tsunami, highlighting a clear need for better understanding
of seismic potential and improved geohazard monitoring in the southern
In this late-breaking session we welcome contributions that characterize
the complex main events and associated aftershocks, discuss the
observations and forecasts of the subsequent tsunami from both
operational and post-event perspectives, address the regional tectonics
of the Scotia Plate, paleo- and historical seismicity, and potential for
future tsunami hazards along the Atlantic coasts of South America,
Africa, and Antarctica.
The session is now open for submissions. Log in 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 August 2021 South
Sandwich Islands earthquake sequence: What happened, regional tectonic
context, and potential for South Atlantic hazards".
The submission deadline is 29 September 2021 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.
Thank you for your attention. We look forward to seeing you virtually or
in person in December.
