A previous attempt to integrate geological, geodetic, and observed seismicity data into a probabilistic-hazard source model predicted a rate of magnitude 6 to 7 earthquakes significantly greater than that observed historically. One explanation was that the discrepancy, or apparent earthquake deficit, is an artifact of the upper magnitude limit built into the model. This was controversial, howev...

Golsar is located in north-west of Rasht the capital city of Guilan province. This region, according to standards 2800, is identified among the regions with relatively high risk of earthquake. A set of historical and instrumental seismicity data used in radius of 200 km which covers the period twelveth century until now. Kijko method has been applied for estimating for parameters considering of...

This paper refers to the present state of historical buildings situated in the Karviná and Ostrava region and also to the problems of these buildings caused first of all by surface vibrations generated by mining-induced seismicity in the Karviná region and by technical seismicity caused by industrial activities and transportation in the Ostrava region. Designing of earthquake-resistant structur...

Recent seismicity and swarm activity in the northern Red Sea have been examined in relation to the tectonics and structures indicated by surface geology and marine magnetic anomalies. Seismicity appears to be low compared to the rest of the Red Sea. Sixty eight earthquakes recorded during the period 1964-1993 had body-wave magnitudes between 3.8 and 6. On 18 February 1992, a swarm of earthquake...

The trifurcation area of the San Jacinto fault zone has produced more than 10% of all earthquakes in southern California since 2000, including the June 2016 Mw (moment magnitude) 5.2 Borrego Springs earthquake. In this area, the fault splits into three subparallel strands and is associated with broad VP /VS anomalies. We synthesize spatiotemporal properties of historical background seismicity a...

One way to probe earthquake nucleation processes and the relation between stress buildup and seismicity is to analyze the sensitivity of seismicity to stress perturbations. Here, we report evidence for seasonal strain and stress (~2–4 kPa) variations in the Nepal Himalaya, induced by water storage variations which correlate with seasonal variations of seismicity. The seismicity rate is twice as...

Abstract. Studies of seismicity induced by water level changes in reservoirs and lakes focus typically on well-documented contemporary records. Can such interactions be explored a historical timescale when the two data types suffer from severe uncertainties stemming different nature data, methods resolution? In this study, we show way to considerably improve correlation between interpolated rec...
