Session of interest at 2021 Seismological Society of America (SSA) Annual Meeting – Amphibious Seismic Studies of Plate Boundary Structure and Processes

Dear Colleagues,

We would like to invite you to submit an abstract to the following session of the virtual 2021 Seismological Society of America (SSA) Annual Meeting (April 19-23). The abstract deadline is January 13, 2021 at 5 p.m. Pacific.

See for meeting and submission details.

Session Title
Amphibious Seismic Studies of Plate Boundary Structure and Processes
Recent years have seen a rapid increase in the number of shore-crossing seismic experiments aimed at characterizing seismicity, deformation and structure at continental margins. Many studies use controlled source imaging in conjunction with continuous recordings of natural seismic sources. Examples of data integration include using ocean-bottom seismometer data in both disciplines and combining results from shallower, high-resolution imaging with deeper, lithospheric-scale studies to understand structures that influence seismicity and plate boundary processes. We invite contributions from the community of seismologists studying plate boundary processes at the transition from onshore to offshore (ocean or lake) environments, including subduction zones, active or relict rifted margins and transform faults.

Objectives: This Town Hall provides a community forum to discuss emerging opportunities for research into lithospheric extensional systems. The end of the NSF funded GeoPRISMS Rift Initiation and Evolution (RIE) initiative, which followed the end of the RIDGE 2000 initiative, creates a need for community discussion of opportunities for multidisciplinary process-oriented research into extensional systems in the next decade. At this meeting we will explore directions for future research, and gauge interest in developing at a later date a community vision that articulates key research challenges and opportunities. The next steps toward understanding lithosphere extension require an integrative approach that considers how processes operate in an array of geological settings, from ridge to rift and in backarcs and broad continental extensional provinces. Processes must also be considered over time scales ranging from tens of millions of years to events that occur in moments, and space scales from intracrystalline creep mechanisms to plates. A multidisciplinary approach is therefore required, as these processes span an array of disciplines and encompass linkages and feedbacks between processes occurring in the solid Earth, hydrosphere and atmosphere.

Best wishes,

Hikurangi Margin Events next week

In an effort to make this virtual AGU more engaging and interactive, the conveners of the session From Trench to Back Arc: Dynamics of the Hikurangi Subduction Zone, would like to invite you to participate in the following events:

  • On 9 December from 18:00 – 19:00 Eastern US Time Zone, we will hold a Poster Walk during which time poster presenters who have indicated interest will give a 4-5 minute talk through of their posters. Use this link to attend:
  • Also on 9 December from 23:05 – 23:30 Eastern US Time Zone, we’ll hold a Breakout Session in which oral presenters will each be in different breakout rooms to talk more about their presentations. Use this link to attend:
Meeting ID: 984 9342 7618
Passcode: 215592

The list of confirmed presenters is attached.

You don’t need to register for AGU to attend these events but you can bring your favorite conference drink to make it feel more like AGU. We hope to see you next week!
