Seismicity analysis and machine learning models for short-term low magnitude seismic activity predictions in Cyprus

, 2020
Effective management and planning for the sustainable development of urban regions requires a wide range of up-to-date and impartial information. This study focusses on earthquake catalog-based seismicity analysis for Cyprus region.

Distribution and morphology of landslides in northern Finland: An analysis of postglacial seismic activity

Geomorphology, 2017
The ages and sizes of landslides occurring in seismically active areas can be used to reconstruct the seismic history of the area and estimate the maximum moment magnitudes of past earthquakes.

Investigation of Seismic Activity

2012
The Caucasus is one of the most active segments of the Alpine-Himalayan seismic belt (Khain 2000). The Caucasian region is characterized by intensive deformation and seismicity that accommodates the continental shortening between the Eurasian and Arabian plates, which are converging at a rate of about 30 mm/year (De Mets et al. 1990; Jackson 1992). The

Exploration of continuous seismic recordings with a machine learning approach to document 20 yr of landslide activity in Alaska

Geophysical Journal International, 2019
Quantifying landslide activity in remote regions is difficult because of the numerous complications that prevent direct landslide observations. However, building exhaustive landslide catalogues is critical to document and assess the impacts of climate ...

The relation of seismic activity and radon concentration

AIP Conference Proceedings, 2014
Radon, which is the largest source of natural ionizing radiation, reaches to surface as gas or dissolved form in the ground water. Emanation of radon can has a profile is disposed to increasing or decreasing depending on the effects of meteorological events or crust movements. In this work, the radon concentration in soil gas, which is transported from

Apollo 14 Active Seismic Experiment

Science, 1972
Explosion seismic refraction data indicate that the lunar near-surface rocks at the Apollo 14 site consist of a regolith 8.5 meters thick and characterized by a compressional wave velocity of 104 meters per second. The regolith is underlain by a layer with a compressional wave velocity of 299 meters per second.

Carbon-14 as a marker of seismic activity

Radiation Effects and Defects in Solids, 2009
Seismic events in volcanic systems can be accompanied by the release of gas from the Earth's crust: of particular interest here is fossil CO2, which contains no trace of carbon-14, and therefore dilutes the carbon-14 present in the surrounding atmosphere.

Stress relaxation in the earth and seismic activity

La Rivista del Nuovo Cimento, 1982
Consideration of the models described in the preceding pages shows that a sound theoretical basis exists for a physical understanding of post-seismic ground deformations and several other phenomena associated with the asthenosphere relaxation. Since the asthenosphere seems to be involved in a direct way in the seismic mechanism, the knowledge of its ...

Seismic active faults in the northwestern Beijing by seismic tomography

Acta Seismologica Sinica, 2007
Using the arrival times of 197 earthquakes well recorded by the Beijing Seismic Network and the China-Germany cooperative Yanqing Digital Seismic Array in the period from October of 2001 to December of 2005, we accurately relocate these earthquakes by the joint-inversion program for hypocentral position and 3-D velocity structure.
