First Annual CERI Field Trip to Southern California, July 25-29, 2022

(August 2022)Prof. Christos Kyriakopoulos and Prof. Thomas Goebel led a group of CERI students on a 5-day field trip along the Southern San Andreas Fault (SSAF) system.

CERI Becomes Voting Member of the Southern California Earthquake Consortium

The University of Memphis Center for Earthquake Research and Information (CERI) is now a core institution of the Southern California Earthquake Center (SCEC). SCEC is a consortium of universities and scientific institutions that performs fundamental research into earthquake processes using Southern California as its principal laboratory. There is substantial overlap of the mission of CERI and SCEC in terms of earthquake science and public outreach. SCEC has functioned as a stand-alone center since 2002 under cooperative agreements with the National Science Foundation and the U.S. Geological Survey. CERI's participation in SCEC will advance knowledge of earthquake processes in the continental interior and increase our understanding of earthquake hazards in Tennessee.

Dr. Christos Kyriakopoulos will be the UofM representative to the SCEC board. More information about SCEC can be found at https://www.scec.org .

FACULTY AWARDS AND RECOGNITIONS

STUDENT AWARDS AND RECOGNITIONS

[Summer  2018 ] Assistant professor Dr. Eric Daub and doctorate student Khurram Aslam wrote a research proposal to Southern California earthquake center (SCEC), which was approved by funding agency. This project uses dynamic rupture simulations combined with long-term tectonic modeling (LTM) to examine how heterogeneous stresses resulting from dynamic earthquake slip on rough faults influence the pattern of postseismic and interseismic strain accumulation. This work will examine the role of time-dependent healing and velocity-dependent deformation through rate and state friction models to capture the temporal characteristics of the transition from dynamic slip to postseismic and interseismic deformation. The Proposal was entitled "Effect of fault roughness and associated inelastic deformation on postseismic and interseismic strain."

[Spring 2018]Assistant professor Dr. Eric Daub, Dr. Eunseo Choi and doctorate student Khurram Aslam wrote a research proposal to Southern California earthquake center (SCEC), which is a further advancement of their previous year proposal. This proposal was  approved by the funding agency. The SCEC Panel said that this research is conceptually well-aligned with the SCEC objective of reconciling multi-cycle deformation models and dynamic rupture models, as this kind of work ultimately should be useful in earthquake forecasting. The title of the proposal was "The influence of rheology on post-seismic and interseismic deformation on rough faults".
