The thick soft superficial layers of the seabed greatly influence ground motion generally. It is worth studying how to find out the influence of these soft layers on ground motion parameters and determine reasonable seismic fortification parameters for ocean engineering. Numerical experiments of site response analysis are designed using two offshor...

AbstractTo solve the problem of antiseismic strengthening, the integer macroseismic intensity of a building is insufficient, because this intensity cannot describe the seismic hazard of a territory. For this, it is necessary to establish the peak ground accelerations and estimate their statistical parameters. The paper constructs the probability de...

We analyzed strong-motion records at the ground and borehole in and around the Kanto Basin and the seafloor in the Japan Trench area from three nearby offshore earthquakes of similar magnitudes (Mw 5.8–5.9). The seafloor strong-motion records were obtained from S-net, which was established to enhance tsunami and earthquake early warnings after the ...

The proposed site of the Diamer Bhasha Dam in northern Pakistan is situated in an active tectonic zone with intensive seismicity, which makes it necessary for seismic hazard analysis (SHA). Deterministic and probabilistic approaches have been used for SHA of the dam site. The Main Mantle Thrust (MMT), Main Karakaram Thrust (MKT), Raikot-Sassi Fault...

A seismic hazard study and analysis of the megathrust source off the west coast of North Sumatra, Indonesia, were conducted based on the estimated horizontal crustal strain using the surface displacement data. This area was selected due to the availability of pre- and co-seismic Global Positioning System (GPS) data for the 2005 Nias–Simeulue Mw 8.6...

Full base shear seismic demand analyses with calculated examples for heavy stone masonry buildings are not present in the literature. To address this shortcoming, analyses and calculations are performed on nominally reinforced rubble stone masonry house and school designs, as typically built in Nepal. The seismic codes are literally applied for cou...

AbstractWe consider the September 21, 2020, Mw = 5.5 seismic event, which occurred in the eastern part of the Tunka rift basin system and was followed by a relatively strong mb = 4.6 aftershock. The earthquake epicenter is localized within the Bystraya basin in the zone of prolonged seismic quiescence and is possibly confined to the Main Sayan faul...

AbstractThe seismic intensity scale is one of the oldest instruments for determining the extent of seismic vibrations. Being initially a descriptive characteristic of seismic impact, intensity has long required only more detailed, thorough consideration and recording of the consequences and manifestations of various primary and secondary effects in...

Including faults as seismogenic sources in probabilistic seismic hazard assessments (PSHA) has turned into a common practice as knowledge of active faults is improving. Moreover, the occurrence of earthquakes in multi-fault ruptures has evidenced the need to understand faults as interacting systems rather than independent sources. We present a PSHA...
