@seismosocam.bsky.socialPreface to the Focus Section on Measuring and Monitoring Seismic Instrumentation #SRL ⚒️
This focus section presents papers that describe procedures, techniques and results related to calibration and performance of seismic instrumentation — both in the field, and in the laboratory.
@seismosocam.bsky.socialSIN‐Polarity: A Novel Algorithm for Automatic Identification of P‐Wave First‐Motion Polarity Based on a Sine‐Wave Template #SRL ⚒️
A new way to select P-wave first-motion polarity could be helpful for focal mechanism calculation.
@seismosocam.bsky.social🌟 OPEN ACCESS 🌟 New research in #SRL found focused on the 2024 magnitude 7.3 Hualien, Taiwan earthquake that structures off the shores of Hualien accommodate a substantial portion of plate convergence. ⚒️
@seismosocam.bsky.socialIn a new #SRL paper, scientists compiled a high-resolution catalog of 23,748 events recorded over three months. This catalog captures the evolution of the magnitude 7.3 Hualien earthquake sequence. ⚒️
@seismosocam.bsky.socialConstructing a High‐Resolution Aftershock Catalog for the 2017 Mw 8.2 Tehuantepec Earthquake Sequence Using a Machine Learning–Based Workflow #SRL ⚒️
The resulting catalog contains 11,374 relocated earthquakes — the most comprehensive published dataset for this sequence.
@seismosocam.bsky.social🌟 OPEN ACCESS 🌟 In a new #SRL paper, scientists transformed a “dark” (unused) telecommunication fiber cable running along Milford Road in Fiordland, Aotearoa New Zealand into a DAS array to monitor avalanches during the 2024 austral winter and spring season. ⚒️
@seismosocam.bsky.socialIntroducing the PyQt framework: a tool that integrates classical seismic data processing workflows with functions specific to distributed acoustic sensing. #SRL ⚒️
@seismosocam.bsky.socialCan real-time monitoring via seismic stations help scientists track when sustained winds turn to serious storm? A new #SRL paper considers how to delineate between storms, windy weather, and calm using microseismic noise. ⚒️
@seismosocam.bsky.socialIn a new #SRL paper, scientists present a distributed acoustic sensing dataset recorded during stimulation operations at Utah FORGE’s EGS site in April of 2024. ⚒️
@seismosocam.bsky.socialCascading Ruptures of the 2022 Chihshang Earthquake Sequence Constrained by Seismic and InSAR Data #SRL ⚒️
Multiple datasets help scientists explore the 2022 Taitung County, Taiwan earthquake sequence.
@seismosocam.bsky.social#SRL introduces DoubleF — a fast and flexible phase association and earthquake location method based on adaptive Sobol sampling. ⚒️
@seismosocam.bsky.socialIn a new #SRL paper, scientists build on the PLUM method and present the Delaunay‐based adaptive technique for earthquake station selection, or DATES, method. DATES adaptively selects reference stations based on local station density and azimuthal coverage. ⚒️
@seismosocam.bsky.socialHow can you integrate distance awareness into the earthquake early warning modeling process? A new #SRL paper introduces TREAD — Transformer for Earthquake Alert with Distance‐awareness. ⚒️
@seismosocam.bsky.social🌟 OPEN ACCESS 🌟 Assessing Earthquake Early Warning Feasibility at the NITRO Near‐Fault Observatory Using Numerical and Offline Simulations #SRL ⚒️
Earthquake early warning at the Northeastern Italy Thrust Faults Observatory? Maybe, suggests a new study.
@seismosocam.bsky.socialIn the most accurate calibration method for seismic stations, a calibrated seismometer is installed near the target seismometer and their local vibration signals are compared. This is on-site calibration. How do you account for temperature changes? Find out, in #SRL. ⚒️
@seismosocam.bsky.social🌟 OPEN ACCESS 🌟 A DAS network in northeastern Italy spans several hundred kilometers of optical fiber, and includes tens of thousands of virtual sensing channels. It’s been integrated into the operational framework of the Seismological Research Center of OGS. #SRL ⚒️
@seismosocam.bsky.socialIn a new #SRL paper, scientists compare earthquake wavefield measurements from an approximately 95 km-long urban dark fiber distributed acoustic sensing array in Dallas, Texas with data from a co-located broadband seismic array. ⚒️

@drjhellenbrand.bsky.social@seismosocam.bsky.socialDynamic Rupture Process of the 2025 7.1 Dingri, Tibet, Earthquake: Insights into the Role of Fault Geometry and Stress Heterogeneity #SRL ⚒️
3D dynamic rupture simulations have implications for seismic hazard assessment of the Shenzha‐Dingjie rift region.
