Planetary Seismology

, 2007
In-situ extraterrestrial seismic measurements have, to date, been limited to data collected during the lunar Apollo missions. These data have provided significant contributions to our understanding of the interior structure of the Moon, and by inference, permissible thermal and mineralogical models.

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica

Boreas, EarlyView.
Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.

Analysis of Stress Variation Characteristics of Jiangling Depression, Hubei, China, Based on Jingzhou Well Water Level and GNSS Data

Geofluids
There have been many M≥3.0 earthquakes in and around the Jiangling Depression in history, and the stress variation can directly affect the preparation of surrounding earthquakes. This paper innovatively uses the variation characteristics of Jingzhou well

Horizontal Clusters and Firm Resilience

Journal of Regional Science, EarlyView.
ABSTRACT The paper examines the role that cluster‐specific horizontal relationships play in firm resilience following a negative shock. We use the Emilia earthquake that hit part of Emilia‐Romagna (Italy) in May 2012 to provide evidence of the negative effect of horizontal clustering on firm performance after a natural disaster.

Effect of Freeze–Thaw Action on Mesostructure of Ecological Fiber Reinforced Loess

Advances in Civil Engineering
Traditional chemical additives inevitably pollute, damage, and destroy the ecological environment and natural resources while simultaneously addressing the requirements of engineering construction in loess areas.

Combining seismology and spectropolarimetry of hot stars [PDF]

, 2014
Asteroseismology and spectropolarimetry have allowed us to progress significantly in our understanding of the physics of hot stars over the last decade. It is now possible to combine these two techniques to learn even more information about hot stars and

Virtual sensing of seismic floor responses for rapid prioritization of critical equipment inspection in nuclear power plants

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Critical equipment in nuclear power plant auxiliary buildings such as control cabinets, panels, transformers, and diesel generators often malfunction before structural damage occurs, demanding rapid post‐earthquake inspection prioritization.

Influence of Fluids and Geological Setting on Source Parameters of the 2010–2014 Pollino (Italy) Seismic Swarm

Terra Nova, EarlyView.
ABSTRACT We analyse variations in Brune stress drop (Δσ), apparent stress (τa) and Savage–Wood radiation efficiency (ηsw = τa/Δσ) during the 2010–2014 Pollino seismic swarm (Southern Apennines, Italy). This prolonged sequence included multiple swarms, with a Mw 5.2 event in October 2012, preceded by a Mw 4.3 event in May 2012, followed by aseismic slip.

Influence of crustal layering and thickness on co-seismic effects of Wenchuan earthquake

Geodesy and Geodynamics, 2011
Using the PSGRN/PSCMP software and the fault model offered by USGS and on the basis of finite rectangular dislocation theory and the local layered wave velocity structures of the crust-upper-mantle, the influences of crustal layering and thickness on co ...
