Seismic hazard analyses are associated with large uncertainties when historical data are insufficient to define secular rates of seismicity. Such uncertainties may be decreased with geological data in areas where seismicity is shallow and produced by Quaternary faulting. To illustrate, we examine intraplate Japan. Large intraplate earthquakes in Japan characteristically produce surface ruptures...

The city of Kolkata, the State Capital of West Bengal is jolted by earthquakes time and again from the tectonic regimes of the Central Himalaya, highly seismogenic Northeast India and the active tectonics of Bengal Basin which is a pericratonic tertiary basin on which the City is located. Earthquake disaster mitigation and management necessitates seismic hazard assessment for the generation of ...

Abstract The joint probability distribution of different intensity measures at sites in one earthquake is needed to define the stochastic process regulating exceedance (in time) ensemble sites, which turn a funding element so‐called multi‐site probabilistic seismic hazard analysis (MSPSHA). simplest model for event requires mean vector and covariance matrix all conditional magnitude location ea...

Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD go...

Abstract The design of critical facilities needs a targeted computation the expected ground motion levels. Trans Adriatic Pipeline (TAP) is pipeline that transports natural gas from Greek-Turkish border, through Greece and Albania, to Italy. We present here probabilistic seismic hazard analysis (PSHA) we performed for this facility, deaggregation results, aiming identify dominant sources select...

Continental intraplate seismicity seems often episodic, clustered, and migrating. The observed seismicity shows both spatial clustering in seismic zones and scattering across large plate interiors, temporal clustering followed by long periods of quiescence, and migration of seismicity from one seismic zone to another. Here, we explore the complex spatiotemporal patterns of intraplate seismicity...

The project entitled Global Ground Motion Prediction Equations is funded by the Global Earthquake Model (GEM) Foundation and has the objective of recommending a harmonized suite of ground motion prediction equations (GMPEs) that can be used at the global and regional scales for seismic hazard analysis and loss estimation studies. As part of this project, Task 1a experts were commissioned to mak...

Analysis of the seismic risk to a structure requires assessment of both the rate of occurrence of future earthquake ground motions hazard and the effect of these ground motions on the structure response . These two pieces are often linked using an intensity measure such as spectral acceleration. However, earth scientists typically use the geometric mean of the spectral accelerations of the two ...
