8 Multidisciplinary studies of fault and earthquake hazard in low-strain environments: Applications to the Intermountain West region (Posters)

This session invites contributions that aim to characterize earthquake hazard within the low-strain Intermountain West region. We encourage abstracts that span field-based paleoseismology and geophysical studies and are particularly interested in interdisciplinary investigations.

Abstract

The Los Alamos Seismic Network (LASN) located in Northern New Mexico, has been in operation since 1976, with 2026 year marking the 50th year anniversary of the network operations. Through its history LASN has supported cutting edge energy projects like Fenton Hill, Test Site Monitoring, and most contemporarily, the Los Alamos Seismic Hazards program. Here, we detail the state of the network including current efforts to modernize operations through instrument, data collection, legacy data curation, and analysis improvements. Since 2019 most of the 19-station network has been upgraded to broadband digital, increasing the fidelity of the data collected. Data acquisition has been improved through the addition of AQMS which enables real-time location capabilities. Legacy data has been mined to better constrain how the network footprint has changed through time and quantify how this change impacts detection thresholds. Using ambient noise tomography, efforts are ongoing to improve our velocity model to reduce location errors. Finally, for the first time, ongoing efforts will enable publicly available continuous data on Earthscope to better monitor and understand the Rio Grande Rift system and the Valles Caldera.
