IRIS WEBINAR - Seismic Constraints on the Subduction Factory - 9/10 2 PM Eastern
From: Andy Frassetto <andyf@xxxxxxxx>IRIS WEBINAR - Seismic Constraints on the Subduction Factory - 9/10 2 PM Eastern
****************************************************************************************************
Back from our summer hiatus...
"Seismic Constraints on the Subduction Factory: from Global to Local Scales" will be presented at 2 pm EDT (6 pm UTC) on Wednesday, 9/10.
Please register if you intend to participate in the webinar live: https://www2.gotomeeting.com/register/823333906
You will be emailed a confirmation containing a link for watching the live broadcast. Afterwards, IRIS will post the webinar here: https://www.youtube.com/playlist?list=PLD4D607C2FA317E6D.
Presenter: Dr. Ellen Syracuse (Post-doctoral Fellow, Los Alamos National Laboratory)
Abstract: Subduction zones are a major _expression_ of tectonics and cause of volcanism on Earth, with a linear extent of approximately 40,000 km at the surface. Their study brings together a variety of disciplines within the geosciences, including seismology, geodynamics, geochemistry, and mineral physics. This cross-discipline study is particularly important, and exciting, when understanding the subarc regions of subduction zones, due to the complexity of processes involved in seismogenesis and melt generation. In this talk, I will focus on a small subset of the many seismic tools that are used to study subduction zones, specifically earthquake relocation and velocity tomography. For example, at the global scale, seismicity can be used to constrain the geometries and consequently the geodynamics and mineralogies of subduction zones, helping us understand the features common to all subduction systems. At a local scale, I focus on Central America, where tomographic studies can provide insight to temperature and fluid distributions and their along-arc variations, linking the inputs to the outputs of subduction zones.
