Meeting Abstracts
The Statewide California Earthquake Center (SCEC) collaborates with academic, government, industry, and other organizations to advance earthquake science, community resilience, and education by: (1) Gathering and analyzing data from field observations and laboratory experiments. (2) Developing system-level models and simulations of earthquake processes to synthesize knowledge as a physics-based understanding of seismic hazard. (3) Communicating that understanding to expand knowledge and reduce earthquake risk.
Participants are invited to present recent work aligned with SCEC priorities during the poster sessions.

Global earthquake monitoring system based on the method of seismic entropy (MSE): By example of California
Samvel Akopian, Anna Bayramyan MSE based on the introduction of new seismic parameters (cumulative energy and entropy), on the concept of a seismic system, and on the law of seismic entropy production. The technology allows to monitor the development of seismic instability in... more Themes: Advancing Community Earth Models for Hazard Analyses | Earthquake Scenarios for Hazard and Risk Assessment | Earthquake Cycle Simulations & Forecasting |

Thermal localization and rheological control on the steady-state width of 1D ductile shear zones
N. Beeler, Hannah Shabtian, Greg Hirth Over geologic time, initiation and growth of upper crustal plate boundary faults, such as that host present Earth's largest earthquakes, are influenced by thermally localized ductile shear zones (DSZ) in the lower crust. Today DSZs influence... more |

Characterization of earthquake source properties for weak events using broadband dynamic rupture models
Frantisek Gallovic, Lubica Valentova K., Lav Joshi, Sara Sgobba Standard characterization of weak earthquakes based on observed source spectra relies on corner frequency (stress drop) and radiated energy estimates only as general source characteristics. However, the standard seismological analysis cannot provide... more Themes: Physics-Based Ground Motion Simulations & Validation |

SEM: Shallow Earth Materials (TAG)
William Griffith, Alexis Ault, Thomas Rockwell, Brady Cox, Eileen Evans, Yihe Huang, Kathryn Materna, Alba Rodriguez Padilla, Hiroki Sone Shallow Earth Materials (SEM), encompassing the upper ~3 km of rock, sediment, and soil, strongly influence earthquake rupture propagation, interseismic creep, near-fault deformation, seismic site response, and the geologic record of past... more Themes: Advancing Community Earth Models for Hazard Analyses | Physics-Based Ground Motion Simulations & Validation | Rapid Post-Earthquake Investigations & Communications |

USGS GNSS data collection and analysis for quantifying interseismic fault creep and imaging slip throughout the earthquake cycle
Jessica Murray, Eleyne Phillips, Ryan Turner Creep is well-documented on several faults of the San Andreas system in northern California. Geodetic measurements of crustal deformation surrounding creeping faults are a primary observation for modeling the rates and spatial distribution of creep... more |

Machine Learning Enhanced Earthquakes Reveal Stress Changes in Icelandic Geothermal Fields
Colin Pennington, Egill Guðnason, Þorbjörg Ágústsdóttir, Anette Mortensen , Rögnvaldur Magnússon Krafla and Þeistareykir geothermal fields in northeast Iceland are respectively one of the oldest and one of the newest geothermal operations in Iceland. Since 2006, continuous monitoring by Iceland GeoSurvey (ÍSOR) for Landsvirkjun has produced a... more |

High Resolution Holocene Slip Rate for the Southern San Andreas Fault at Salt Creek, Salton Trough, California
Thomas Rockwell, Katherine Scharer, Nathan Brown, William Buckley, Paula Figueiredo, Andrea Fabbrizzi We present a new geologic slip rate determined for the southernmost San Andreas Fault (sSAF) within a relatively linear fault segment situated adjacent to the modern-day Salton Sea about 16 km from the southern end of the fault at Bombay Beach. This... more Themes: Advancing Community Earth Models for Hazard Analyses |

The Collaboratory for the Study of Earthquake Predictability in China: Experiment Design and Preliminary Results of CSEP2.0
Shengfeng Zhang In earlier CSEP1.0 experiments in China, the PI model was used for alarm-based, intermediate-to-long-term forecasts of earthquakes with magnitude MS ≥ 6.0 in the Yunnan–Sichuan region (Zhang et al., 2016). That study adopted a magnitude cutoff of 3.... more Themes: Advancing Community Earth Models for Hazard Analyses | Earthquake Scenarios for Hazard and Risk Assessment |
