Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Meeting Abstracts

The SCEC collaboration emphasizes the connections between information gathering by sensor networks, fieldwork, and laboratory experiments; knowledge formulation through physics-based, system-level modeling; improved understanding of seismic hazard; and actions to reduce earthquake risk and promote resilience. Use the form below to search and view all poster and invited talk abstracts submitted to this meeting.


  
  

A SCEC username is required to submit an abstract.

The person submitting the abstract is automatically the First Author, and will receive all communications regarding the abstract.

First Authors can submit a maximum of one poster presentation abstract and one oral presentation abstract (if invited as a plenary speaker).

Abstracts should not exceed 2,500 characters in length.

Every poster will be on display from Sunday evening through Tuesday evening.

Ridgecrest Vertical Deformation of the 2019 M6.4 Searles Valley and M7.1 Ridgecrest Earthquakes
Bridget Smith-Konter, Lauren Ward, Xiaohua Xu, David Sandwell
On July 4-5, 2019, the M6.4 and M7.1 Searles Valley and Ridgecrest earthquake sequence ruptured a geometrically complex 50 km long system of faults within the Eastern California Shear Zone (ECSZ). These conjugate events resulted in several meters... more

Ridgecrest Prediction of Ground-Motion Time-Series at an arbitrary location using Gaussian Process Interpolation: Application to the Ridgecrest Earthquake
Aidin Tamhidi, Nicolas Kuehn, Yousef Bozorgnia, Ertugrul Taciroglu, Tadahiro Kishida
Every seismic event is recorded only at a finite number of locations. In many engineering applications a variety of seismic intensity measures (IMs), typically peak ground acceleration or response spectrum, are required as input, that are estimated... more

Ridgecrest Anti-similar aftershocks in the Ridgecrest, California earthquake sequence
Daniel Trugman, Zachary Ross, Paul Johnson
Similar earthquakes - pairs of events with highly similar waveforms - rupture overlapping or adjacent fault patches with similar slip mechanisms. Close examination of the characteristics of similar earthquake pairs have been used for a variety of... more

Ridgecrest NOTA Performance During 2019 Ridgecrest Earthquake Sequence
Christian Walls, Doerte Mann, David Mencin, Kathleen Hodgkinson, Shawn Lawrence, Andre Basset, Ryan Turner, Karl Feaux, Glen Mattioli
The Ridgecrest earthquake sequence occurred within the footprint of the Network of the Americas (NOTA), which federates the former EarthScope Plate Boundary Observatory, TLALOCNet in Mexico, and COCONet in the Caribbean. NOTA is operated by UNAVCO... more

Ridgecrest Modeling of co- and early postseismic deformation due to the 2019 Ridgecrest earthquake sequence
Kang Wang, Roland Bürgmann
On July 4th, 2019, a Mw 6.4 earthquake struck the Searles Valley near the town of Ridgecrest in southern California. The Mw 6.4 earthquake was followed by a Mw 7.1 event about 30 hours later. Both the Mw 6.4 foreshock and the Mw 7.1 mainshock... more

Ridgecrest Detailed fracture map and orthophoto of the southern portion of the M6.4 2019 Ridgecrest Earthquake
Alana Williams, Ian Pierce, Rich Koehler, Sinan Akciz, Colin Chupik, Jayne Bormann
An M6.4 foreshock struck on July 3, 2019, near Ridgecrest, California, and ruptured bilaterally. The mainshock, An M7.1 event, followed this earthquake on July 5. Between July 4 and July 9, low altitude aerial photos were acquired along ~12 km of... more

Ridgecrest Aftershocks of the Ridgecrest earthquake sequence on four dense fiber seismic arrays
Ethan Williams, Zhongwen Zhan, Zefeng Li, Martin Karrenbach, Thomas Coleman, Lisa LaFlame, Steve Cole, Victor Yarsev
Recent advances with distributed acoustic sensing (DAS) have demonstrated the ability of pre-existing telecommunications cables to be repurposed as dense arrays of linear strainmeters, effective for scalable seismic monitoring. The extensive fiber... more

Ridgecrest Dynamic stress perturbation on the M7.1 Ridgecrest earthquake fault from the preceding M6.4 event: a theoretical study with dynamic rupture models
Baoning Wu, David Oglesby, Jordan Cortez, Christodoulos Kyriakopoulos
The 2019 Ridgecrest earthquake sequence included a M6.4 event and a M7.1 event occuring 33 hours apart, rupturing two perpendicular faults. Questions arise about how much the M6.4 event contributed to the M7.1 rupture. While the detailed rupture... more

Ridgecrest Imaging the rupture process of the 2019 M6.4 and M7.1 Ridgecrest Earthquakes using local seismic stations in Southern California
Yuqing Xie, Lingsen Meng
The M6.4 and M7.1 Ridgecrest earthquakes shocked downtown LA in July 2019. The earthquakes draw many attentions since they are among the largest earthquakes in Southern California over the past two decades. They are recorded by the dense strong... more

Ridgecrest Automated moment tensor inversion using 3D Green’s Functions: Application to the LA basin and the 2019 Ridgecrest sequence
Zhongwen Zhan, Xin Wang
Earthquake focal mechanisms put primary control on the distribution of ground motion, and also bear on the stress state of the crust. Most routine focal mechanism catalogs still use 1D velocity models in inversions, which may introduce large... more
