Abstract Identification of repeating earthquakes (repeaters) usually depends on waveform similarity expressed as the corresponding cross‐correlation coefficient (CC) above a prescribed threshold, typically ranging in 0.70–0.98. However, robustness and effectiveness such strategy have rarely been fully examined. In this study, we examine whether CC is valid proxy for repeater identification through both synthetic real earthquake experiments. We reveal that controlled by not only interevent...

Abstract This work presents the implementation of an advanced deep-learning (DL)-based earthquake detection workflow on Bhutan Pilot Experiment dataset, a five station seismic network that was deployed from January 2002 to March 2003 in Bhutan’s Eastern Himalaya region. Previous studies reported 175 local earthquakes this not fully understanding seismicity potential and tectonic settings area. To enhance location accuracy, we reprocess dataset using hybrid-pair-input DL model combined with...

Abstract Waveform match‐filtering (MF), based on cross‐correlation between an earthquake pair, is a powerful and widely used tool in seismology. However, its performance can be severely affected by several factors, including the length of window, frequency band applied digital filter, presence large‐amplitude phase(s). To optimize MF, we first systematically examine effects different operational parameters determine generic rules for selecting window optimal passband. minimize influence...

Abstract Repeating earthquakes (repeaters) are events that recurrently rupture the same fault patch with nearly identical magnitudes. Although repeaters have been widely studied and utilized in many fields over last four decades, there no standard criteria for reliably identifying such events. The current adopted geophysical research community inconsistent difficult to justify. Different may inescapably incur inadequate hypotheses lead controversial interpretations, highlighting urgent need...

Seismic networks monitor seismic activities across the globe, recording distinctive events within specific geographical and temporal frames. Whether old or new, each record preserves valuable information, with its extraction relying mainly on sophistication of method. This study presents implementation an advanced earthquake detection workflow a relatively dataset, Bhutan Pilot Experiment. temporary five-station network in Eastern Himalaya comprised set Broadband sensors deployed for 14...

Abstract Earthquakes resulting from hydraulic fracturing (HF) can have delayed triggering relative to injection commencement over a varied range of time scales, with the majority M ≥ 4 mainshocks occurring near/after well completion. This poses serious challenges for risk mitigation and hazard assessment. Here, we document high‐resolution, three‐dimensional source migration process mainshock that is controlled by local hydrogeological conditions near Fox Creek, Alberta, Canada. Our results...

Abstract The Explorer segment of northernmost Cascadia is an end‐member “warm” subduction zone with very young incoming plate and slow‐convergence rate. Understanding the megathrust earthquake potential this type both geodynamic societal importance. Available geodetic observations indicate that currently locked to some degree, but downdip extent fault area potentially seismogenic not known. Here we construct finite‐element models estimate thermally allowed zone, using available knowledge...

Abstract Seismic source locations are fundamental to many fields of Earth and planetary sciences, such as seismology, volcanology tectonics. However, seismic detection location challenging when events cluster closely in space time with signals tangling together at observing stations, they often do major aftershock sequences. Though emerging algorithms artificial intelligence (AI) models have made processing high volumes data easier, their performance is still limited, especially for complex...

Seismic precursors prior to the failure of rocks are essential for probing nucleation process and mitigating hazards. However, such precursory events before large landslides rarely reported possibly due lack near-source observations. The 2017 Nuugaatsiaq, Greenland landslide that was preceded by an abundance small earthquakes captured a local seismic station is notable exception offers us valuable opportunity investigate how initiated. Prior work suggests accelerated creeping plays important...
