Speaker: Dr. Alexandros Savvaidis, Texas Seismological Network (TexNet) and Center for Integrated Seismicity Research (CISR) at the Bureau of Economic Geology (BEG)

An increase in induced seismicity in the central U.S. since 2009 led to establishment of TexNet seismic-monitoring in Texas.  Accurate, absolute seismic-event location is critical to TexNet, allowing association of seismicity with human activity. In order to achieve that, different velocity models and methods have been used to identify absolute locations. Following that a probabilistic association has been established between seismicity and oil and gas operations in part of West Texas. This study indicates that most of the earthquake activity is  likely caused by hydraulic stimulation rather than salt water disposal.

Speaker Biography: Dr. Alexandros Savvaidis, Texas Seismological network (TexNet) and Center for Integrated Seismicity Research (CISR) at the Bureau of Economic Geology (BEG)
Dr Alexandros Savvaidis is the Manager of the Texas Seismological Network (TexNet) and Seismology Research Team Lead at the Center for Integrated Seismicity Research (CISR) at the Bureau of Economic Geology (BEG) at UT Austin. Dr Savvaidis has more than 20 years’ experience in Applied Geophysics and Seismology. Prior to joining the BEG, he held the position of Senior Researcher at the Institute of Seismology and Earthquake Engineering at Thessaloniki, Greece. From 2008 until 2015 he was managing the largest Seismographic Network in Greece, numbering 100 real time accelerometers and 150 offline installations. During his extensive career he coordinated several collaborations with academic and industrial partners in multidisciplinary European funded projects. During 2008 and 2012 he has been a visiting researcher at the University Joseph Fourier in Grenoble and University of Potsdam respectively.
