2021 Extreme Weather Events - Deadline for submission: 29 September 2021 23:59 EDT/03:59 +1 GMT

The catastrophic floods in regions including Europe and China, and the heat waves spreading around North America in the summer of 2021 are yet another reminder of the increasing extreme weather events in a changing climate. With an ongoing global pandemic, our societies are faced with dual challenges, which require mitigation and adaptation strategies rooted in scientific understanding. In this late breaking session, we welcome submissions on related topics including but not limited to: studies of the physical processes contributing to the extreme weather events, monitoring and predictions of precipitation and water discharges at the watershed scale and/or in densely populated urban regions, responses of natural systems to such perturbations, resilient infrastructures that minimize the impacts of extreme weather events (e.g., heavy rainfall triggered landslides), and social justice and/or potential disparities in public health in affected regions. Interdisciplinary studies are particularly encouraged.

The 2021 Haiti Earthquake - Deadline for submission: 29 September 2021 23:59 EDT/03:59 +1 GMT

The 2021 August 14 Mw 7.2 Haiti earthquake ruptured the Enriquillo-Plaintain Garden Fault Zone (EPGFZ), part of the CA-NA plate boundary, approximately 75 km west of the epicenter of the 2010 Leogane Haiti earthquake. The rupture is complex and appears to have (1) ruptured multiple fault segments, (2) slipped in a highly oblique sense on what had been previously thought a primarily strike-slip fault, and (3) not ruptured the fault segment immediately adjacent to the 2010 earthquake location, suggesting increased seismic potential in the future. The event provides an opportunity to constrain the kinematics and geometry of the EPGFZ, as well as probe the regional stress state.

In this session we invite proposals related to seismic, geologic, and tectonic processes associated with the 2021 Haiti earthquake, including field reconnaissance, geodetic and seismic source characterization, regional geologic structures, and damage from the event, as well as physical models for slip.

The August 2021 South Sandwich Islands earthquake sequence: What happened, regional tectonic context, and potential for South Atlantic hazards - Deadline for submission: 29 September 2021 23:59 EDT/03:59 +1 GMT

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 oceans. 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.
