Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Sustainable Development, EarlyView.ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Non double couple seismic sources, faults interaction and hypothesis of self-organized criticality [PDF]
Natural Hazards and Earth System Sciences, 2005 Non double couple (NDC) sources are considered in framework of the hypothesis that the process of seismic rupture can be viewed as a result of complicated fault geometry and its segmentation.

Earthquake fault-plane solutions and patterns of seismicity within the Umbria Region, Italy
Annals of Geophysics, 2006 In this paper we present a review of the seismotectonic features (an analysis of earthquake focal mechanisms and the distribution of seismicity) of the Northern Apennines, Umbria Region (Italy) in the area between Sansepolcro and Norcia.

Global seismicity of 1982: centroid-moment tensor solutions for 308 earthquakes
Physics of the Earth and Planetary Interiors, 1983 Abstract The centroid-moment tensor analysis is applied to digital recordings of 308 moderate and large earthquakes that occurred during 1982 and were recorded by the Global Digital Seismograph Network (GDSN) and International Deployment of Accelerometers (IDA) networks. The tables contain numerical results for all events.

Designing Elastic Softening Under Compression via Dipole–Dipole Interactions: The Case of Na2TiSiO5
Small, EarlyView.Pressure usually stiffens solids, yet Na2TiSiO5 exhibits anomalous elastic softening under compression. Unlike conventional mechanisms driven by geometric rearrangements or electronic spin‐state transitions, the softening originates from enhanced dipole coupling along head‐to‐tail TiO5 chains.

Frontiers in Earth Science, 2018 Detailed models of low-frequency seismicity at volcanoes provide insights into conduit structure and dynamics of magmatic systems. Many active volcanoes produce repetitive seismic events, but these are often too small to model on their own.
