Patterns and Drivers of Cliff Erosion in Big Sur, California, USA Using Repeat Photogrammetry, 2017–2023

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Seacliff erosion in steep terrain poses major risks to transportation and critical infrastructure. In Big Sur, California, USA, seacliff erosion threatens the sustainability of the central coast stretch of California State Route 1, a transportation corridor that is critical to the region's economy.

Solution of Microseismic Monitoring Non-Linear Location Equations Based Matlab

, 2011
Microseismic will produce when rock mass break. The occurrence of microseismic monitoring has close relationship to the energy release and crack's evolution in the rock mass. Therefore the microseismic monitoring can be used to predict the future rupture

Evaluating Deep‐Learning‐Based Earthquake Detection in a Sparse Coastal Network: Insights From the 2017 Changdao Swarm, Eastern China

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Constructing reliable earthquake catalogs in regions with sparse station coverage and strong noise remains challenging. We evaluate the performance of a deep‐learning–based detection and location workflow (LOC‐FLOW) using the 2017 Changdao offshore earthquake swarm in eastern China.

Crustal and Upper Mantle Structure Beneath the Corinth Rift Using Receiver Function Analysis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Gulf of Corinth is one of the fastest‐extending continental rifts in Europe, yet the link between present‐day strain, inherited crustal structure, and lithospheric dynamics remains debated. We investigate crustal thickness and Vp/Vs variations using receiver functions from 31 seismic stations.

Application of microseismic monitoring in the optimization of control strategy for roofs composed of composite hard sandstone masses

Meitian dizhi yu kantan
Objective With a gradual increase in the coal mining depth in China, the movement of overlying thick and hard rock layers exerts increasingly complex impacts on the mine pressure. Methods In the Ordos area, the overburden of the mining face of most mines

Geophysical Signals Induced by Magma Propagation: Insights From Analog Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The propagation of magma through the Earth's crust often generates seismic signals and surface deformation, both key indicators of volcanic unrest. While surface deformation is attributed to magma emplacement within fractures, identifying the exact source of the seismic signal remains challenging. Such signals could stem from fracturing at the

Effective VTI anisotropy for consistent monitoring of microseismic events

, 2011
The monitoring of induced or triggered microseismic events increasingly is being used to inform the efficient production of unconventional reservoirs. A key aspect of economic production in these low-permeability rocks is hydraulic fracture stimulation,

Shear‐Wave Splitting Measured for Permanent Reservoir Monitoring Systems: An Example From the Snorre Field

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Microseismic monitoring of offshore CO2$\rm CO_2$ storage projects is likely to include some deployment of offshore sensors. To improve the value proposition of this monitoring infrastructure, it is important to consider what other information can be gained about the CO2$\rm CO_2$ storage complex and the surrounding region.

Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Studies of small earthquake (M < 2) rupture processes traditionally rely on simplified models that assume symmetric slip or point sources. Using an exceptionally dense seismic network and empirical Green's function (EGF) analysis, we investigate the complex rupture of a Mw 1.6 microearthquake induced by hydraulic fracturing.
