[1] The southwestern half of a 500 km long seismic gap in the central Kuril Island arc subduction zone experienced two great earthquakes with extensive preshock and aftershock sequences in late 2006 to early 2007. The nature of seismic coupling in the gap had been uncertain due to the limited historical record of prior large events and the presence of distinctive upper plate, trench and outer r...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

Thrust collision zones with low slip rates along the plate boundary are significant areas of stress accumulation and prone to develop more destructive earthquakes longer recurrence intervals. Such regions often classified as seismic risk if they lack continuous records large earthquakes, such eastern Tibetan Plateau before 2008 M w 7.9 Wenchuan earthquake. Here, we provide a record in Longmen S...

The precise location of the seismic source 1755 CE Great Lisbon earthquake is still uncertain. aim this work to use an onland sedimentary record in southern Portugal test and validate sources for earthquake. To achieve this, tsunami deposit thicknesses from over 150 cores collected at Salgados were compared results a sediment transport model (Delft3D-FLOW) that simulates propagation, inundation...

An M L = 3.5 earthquake near Santa Maria, California, was recorded by the Southern California Seismic Network and a TERRAscope station at Santa Barbara (SBC) on 31 January 1991. The waveform of this event is dominated by 2to 5-sec waves, and is different from that of ordinary events with similar size. Inquiries into operations in several oil fields in the area revealed that hydro-fracturing at ...

It seems counter-intuitive to assert that simple, unsophisticated, non-engineered, timber and masonry structures might be safer in large earthquakes than new structures of reinforced concrete, but such has proven to be the case in a number of recent earthquakes, including the Izmit and Düzce earthquakes in Turkey of 1999, the Bhuj earthquake in India of 2001, and the Kashmir earthquake in Pakis...

In order to better research the role helicopter played in the earthquake rescue, a helicopter earthquake rescue mission modeling method based on multi-agent was proposed. The elements of the earthquake environment modeling were described. Typical helicopter rescue missions in earthquake relief were divided into three basic types, and the mission flow was carded. The division and function of age...

The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of ...
