About

Space weather variations can be associated with beautiful aurora displays and harmful effects on technological infrastructure from the induced electromagnetic currents. Regular interactions of solar and cosmic particles with the Earth’s magnetic field and ionosphere can also be used as probes of the Earth's interior, for example for magnetotelluric methods, which in turn allows constructing space weather hazard maps. This meeting will explore the diverse consequences and applications of space weather phenomena to solid Earth geophysical questions, as well as the geophysical tools used to study space weather.

About

Meeting description:

Accurate modeling of Glacial Isostatic Adjustment (GIA) is becoming increasingly important as observations of global change contain a complex mix of signals from GIA and anthropogenic effects such as climate change and human-induced land subsidence. For example, uncertainty in the long-term GIA correction can be the limiting error source in determining quantities such as the integrated ice sheet mass balance. Uncertainties in GIA modeling arise from a number of sources, including a range of solid Earth transients which are governed by complex rock rheologies. A better understanding of the Earth's 3-D viscosity structure is thus needed, and such efforts require joint approaches with work to reduce errors in ice loading models, for example. Some legacy constraints remain to be fully integrated for a consistent picture, and a wealth of new datasets, including crustal motions from GNSS and the changing gravity field from satellite measurements, can further propel better GIA models. Such work can also benefit from integration of constraints on mantle rheology from laboratory experiments, regional transient studies, seismic imaging, and global mantle flow modeling. This workshop will focus on recent advances, and discuss new ideas for improving integrative GIA modeling toward meeting the stringent demands for predictive solid Earth modeling today.

Recent years have seen significant increases in machine learning (ML) applications in detection, classification, and prediction type problems, including in geophysics. Since the COSEG workshop in 2019 on “Beyond the Black Box”, much has changed. Some detection type approaches have become near standard, but there is still much to be learned when it comes to reproducibility, uncertainties, extrapolation limits, and knowledge gains involved. This meeting brings together practitioners and theoreticians from outside the disciplines, and from within, to explore the advances in fields such as physics constrained ML, physics discovery ML, and causality to explore where things stand as to usage of ML technique to improve insights into physics and dynamics of systems.

Time-Dependent Earthquake Hazard: Committee on Solid Earth Geophysics Spring 2022 Meeting

1:00 PM - 5:00 PM (ET)

Past

Agenda

Download the Agenda

About

Earthquake behavior is known to experience time dependent behavior. For example, earthquakes slip in response to a long preceding period of interseismic stress accumulation and repeated rupture of a given fault patch is not expected shortly after a major earthquake. More generally, stress transfer between faults is widely recognized, such that a given earthquake might bring other faults or fault segments closer to (or farther from) failure. However, aside from the specific case of aftershock forecasts, quantifying time-dependent hazards has long been challenging.

Estimating earthquake hazards requires not only an understanding of stress transfer in the lithosphere, but also knowledge of regional tectonics and geology. This information, combined with measurements of ground shaking, allows scientists to make a probabilistic hazard maps of future shaking intensities. Although these maps represent, at best, a “snapshot in time,” they are often used without full critical evaluation in downstream engineering applications. Creating frameworks to capture the changing nature of time-dependent hazard, such as new earthquake occurrence or other tectonic or human processes (such as slow slip earthquakes, earthquake swarms, or fracking), is an area of cutting-edge research.

About

Plate tectonics provides the overarching framework for understanding active plate boundary processes, such as earthquakes and volcanic eruptions, interpreting Earth’s geologic record, and quantifying thermo-chemical exchange between Earth’s surface and deep interior through geologic time. While the broad picture of plate tectonics has been understood since the early 1960s, fundamental questions remain regarding how tectonic plates form and remain intact, how localized deformation is accommodated between and within rigid plates, and the efficiency of plate tectonics over Earth’s history.

This meeting brings together a diverse range of approaches for studying plate tectonics, including geophysical imaging, seismic and geodetic observations of deformation, field studies, laboratory experiments, and numerical modeling. Key topics to explore include how oceanic and continental plates form and evolve, the internal structure of lithospheric plates and the lithosphere-asthenosphere boundary, and the processes that cause plate boundaries to localize. These topics are particularly timely given recent initiatives focusing on plate tectonic processes, including Pacific Array, Rift2Ridge, and SZ4D.

Solid Earth Science and Sea Level Change: COSEG Fall 2020

November 12 - 13, 2020

Past

Materials

About

Download Agenda Booklet

Sea level change is one of the most critical environmental and socioeconomic problems facing modern society. It is of paramount importance to predict how much sea level will rise in the future and how it will impact coastal populations and infrastructure. Sea level change involves complex interactions among the atmosphere, oceans, and the land surface; each component must be understood to assess not only how sea level is changing now, but how it will change in the future. The role of the solid Earth and land surface is a vital piece of the puzzle. Vertical land motion can exacerbate relative sea level change in areas of subsidence or buffer against sea level change in areas of uplift. The solid Earth is still deforming in response to mass changes from ice that melted thousands of years ago, as well as ice that is melting today. This deformation changes sea level through the vertical land motion it causes and its changes to the gravity field of the Earth, which causes “imprints” of the ice sheets in the spatial patterns of sea level change. Measurements of sea level change can therefore be used to infer properties of the solid Earth that drive this deformation.
This meeting will review the state of sea level science, discuss the role of solid Earth science in studying sea level change, and delve into the important questions that we need to answer in the future.
