(March 2023) CERI graduate student Anuradha Mahanama (Maha) was recently selected by NASA for participation in the final round of the NASA InSightSeers Program, which is intended to expose early-career scientists to the experience of working on a mission science team. InSight was a Mars geophysical mission that officially ended in 2022 (https://mars.nasa.gov/insight/timeline/overview/), but remains active with data analysis and archiving. Maha was one of ten applicants chosen for this final round of the InSightSeers Program based upon their career paths and the alignment of their research interests with the mission’s scientific objectives.

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. The group followed the SSAF, with a diversion to visit the Elsinore Fault system, from Bombay Beach (the assumed southern "end" of the SAF) to the impressive displacement features observed in the Carrizo plain (Central California), visiting world class geologic sites and making observations on a variety of earthquake related physical processes. Some highlights included: Standing on top of the fault at the Carrizo plain (probably the most iconic SAF site), manually crushing “pulverized” fault rock to powder along the Mojave segment, cooling our feet in a sag pond, climbing pressure ridges, observing mud volcanoes in the Salton Sea geothermal area, exploring an SSAF geologic trench near Bombay Beach...and many other things.

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
[October, 2016] CERI faculty Dr. Christine Powell has won the 2016 Jesuit Seismological Association Award given annually by the Eastern Section of the Seismological Society of America. The award is given for outstanding contributions to observational seismology particularly towards the understanding of seismology and/or seismotectonics in eastern North America. Professor Powell has made extensive studies of the major intraplate seismic zones of North America including the New Madrid, the Eastern Tennessee, and the Charlevoix, Canada, Seismic Zones. the award is named after the Jesuit Seismological Association that operated the first world-wide network of seismic stations in the early 20th Century. Professor Powell will receive her commendation at the upcoming annual meeting of the Eastern Section that will be held in Reston, Virginia, October 23-26, 2016.
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".
