Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

The Possible Observation of Slow Slip Events Prior to the Occurrence of the 1999 Chi-Chi Earthquake
Terrestrial, Atmospheric and Oceanic Sciences, 2012 Possible short-term precursors several days before the Taiwan Chi-Chi earthquake (Mw = 7.6) on 20 September 1999 were observed by examining crustal deformation that were directly integrated from broadband velocity seismograms.

Deep Underground Science and Engineering, EarlyView.This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Slip bursts during coalescence of slow slip events in Cascadia
Nature Communications, 2020 Slow slip events are commonly observed on natural faults all around the world and are suggested to precede large magnitude and/or high frequency earthquakes.

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins
Geophysical Research LettersA tectonic tremor is a successive seismic signal observed along plate boundaries in subduction zones. However, the source processes and mechanisms responsible for the tremor remain unclear. Quartz‐filled shear and extension veins are clustered in tens to
