About Temblor


 

Temblor, Inc. is an innovative catastrophe modeling company specializing in seismic hazard and risk assessment. Founded in 2014 by former USGS scientists Ross Stein and Volkan Sevilgen, Temblor’s mission is to raise awareness of seismic risk. We serve the insurance, reinsurance and insurance-linked security communities, and mortgage lenders.

Temblor is different from other cat modelers. Our models build on recent published and independently-tested scientific analyses to provide an independent, unbiased, and transparent assessment of risk. Our products include dynamic hazard and loss forecasts after large earthquakes; the first globally consistent insurance loss model; stochastic event sets; and the highest-resolution global site amplification model available today. Additionally, we calculate a building-level Temblor Earthquake Score, which folds in all factors that impact loss into one number for risk pricing and selection.

Temblor provides both its clients and the public with accurate, accessible, and understandable information about earthquakes. Temblor Earthquake News publishes breaking earthquake news, in-depth analyses, and expert reporting on the latest developments in natural hazards research. Our articles are written by scientists, science journalists, and leading international researchers.

 


Temblor Team

 

Volkan Sevilgen, M.Sc. — cofounder and CTO
volkan@temblor.net
Volkan Sevilgen, CTO and co-founder, leads Temblor’s scientific programming and technology development. Volkan received an M.Sc. in Geophysical Engineering from Istanbul Technical University (ITU) in 2006 following a B.Sc. from ITU in 2003. He worked at the USGS, Menlo Park between 2006 – 2014, where he co-authored, developed and taught the Coulomb 3 earthquake stress and deformation software, and managed a four-year probabilistic seismic hazard assessment for the Balkan countries funded by USAID’s Office of Foreign Disaster Assistance. His studies on earthquake hazard and Coulomb stress interaction were published by Nature, the Proceedings of the National Academy of Sciences, and other distinguished geophysics and seismology journals. He is president-elect of the Northern California Chapter of the Earthquake Engineering Research Institute (EERI)

Ross S. Stein, Ph.D.cofounder and CEO
ross@temblor.net
Ross S. Stein is Temblor CEO and cofounder, Adjunct Professor of Geophysics at Stanford University, former USGS Senior Scientist, a 2019 Centennial Lecturer of the American Geophysical Union, and 2020 Distinguished Lecturer of the Seismological Society of America. A Fellow of the American Geophysical Union and Geological Society of America, Stein received the 2012 Gilbert F. White Natural Hazards Award from AGU, gave a 2012 TEDx talk, ‘Defeating Earthquakes,’ and received the 2000 Eugene M. Shoemaker Distinguished Achievement Award of the USGS. In 2003, the Science Citation Index reported that Stein was the second most cited author in earthquake science during the preceding decade; he was tenth most cited during 1900-2010. Stein frequently brings insights to the public media interviews, TEDx and public talks, and in IMAX and Discovery Channel films. In 2010, Stein cofounded the Global Earthquake Model (GEM Foundation), chairing its Science Board until 2015. Stein is a member of the Resilient America Roundtable of the National Academy of Sciences, and the Advisory Council on Catastrophes of Zurich Insurance.

Shinji Toda Temblor
Shinji Toda, Ph.D. — Geophysicist and Developer
Shinji is Professor of Earth Sciences at Tohoku University in the International Research Institute of Disaster Science (IRIDeS). Because of its unmatched monitoring networks and high quake rate, Japan is the world’s most important proving ground for seismic innovation and discoveries. Shinji is developing and testing tools with Temblor to capture the change in seismic hazard following large earthquakes.

 


Tiegan Hobbs Temblor
Tiegan E. Hobbs, Ph.D., MSCEDeveloper & Researcher
Tiegan is a Postdoctoral Researcher at Natural Resources Canada in Vancouver, B.C., assessing seismic risk in British Columbia. She received her Ph.D. in Geophysics and her M.Sc. in Civil Engineering in 2019 at the Georgia Institute of Technology. She has studied Coulomb stress transfer to probe earthquake interaction, shear wave splitting to study fault structures, and used seismic and geodetic data to investigate postseismic relaxation of megathrusts to understand the seismic cycle.

 


Alka Tripathy-Lang, Ph.D. — Writer/Researcher

Alka received her Ph.D. in Geosciences from Arizona State University in 2011. Her doctoral work focused on thermochronology, geochemistry and remote sensing in the western Himalaya of India. As a postdoc at the Berkeley Geochronology Center, she worked on projects involving the topographic evolution of places like Tibet, Yosemite Valley and the Grand Canyon. She then set out to pursue her passion for science writing and science communication.
