It is of great significance for emergency rescue to rapidly assess damage buildings after an earthquake. Some previous methods are time-consuming, data difficult obtain, or there lack regional assessment. We proposed a novel way building by comprehensively utilizing earth observation-derived and field investigation alleviate the above problems. These related hazard-causing factors, hazard-forma...

An extensive analysis of the strong ground motion Mexican data base was conducted using Soft Computing (SC) techniques. A Neural Network NN is used to estimate both orthogonal components of the horizontal (PGA h ) and vertical (PGA v ) peak ground accelerations measured at rock sites during Mexican subduction zone earthquakes. The work discusses the development, training, and testing of this ne...

SUMMARY We derived new, reversible relationships between macroseismic intensity (I), expressed in either the European Macroseismic (EMS-98) or Mercalli–Cancani–Sieberg (MCS) scales and peak ground acceleration (PGA), velocity (PGV) spectral (SA) at 0.3, 1.0 3.0 s [SA(0.3), SA(1.0) SA(3.0)] for Italy. adopted orthogonal distance regression technique to fit a quadratic function. This research aim...

On-site earthquake early warning techniques, which issue alerts based on seismic waves measured at a single station, are promising, and have performed quite successfully during some damaging earthquakes. Conventionally, most existing techniques extract several P-wave features from the first few seconds of after trigger to predict intensity or destructiveness an incoming earthquake. This type te...

In recent years, the development of seismic networks in Metropolitan Lima, administrated by public and private institutions, has received special attention since it makes possible quantification different indexes under occurrence earthquakes. Therefore, integration information both from acceleration sensors site conditions microzoning studies allows estimation extent damage quasi-real time. thi...

Abstract Dams are parts of the critical infrastructure any nation, failure which would have a high-risk potential on people and properties within dam vicinity. Ghana is one most seismically active regions in West Africa has at least 5 large dams across region, constructed strategic locations. The area characterised by low-to-moderate seismicity, yet historical events suggest that major earthqua...

Abstract Deep-sea turbidite has been used to determine the history of occurrence large earthquakes. Surface-sediment remobilization is a mechanism generation earthquake-induced turbidity currents. However, detailed surface-sediment caused by earthquake ground shaking unclear. To understand how high peak acceleration (PGA) can remobilize surface sediments, we determined age core recovered from m...

Probabilistic seismic hazard analysis is a technique for estimating the annual rate of exceedance of a specified ground motion at a site due to the known and suspected earthquake sources. A Monte-Carlo approach is utilized to estimate the seismic hazard at a site. This method uses numerous resampling of an earthquake catalog to construct synthetic catalogs to evaluate the ground motion hazard a...

In this paper, the peak ground acceleration (PGA) over the bedrock is calculated by a probabilistic and deterministic seismic hazard assessment. An active fault map of the region is prepared. For this purpose, all active faults in a radius of 100 km from Amol city center are recognized and their seismic and rapture parameters are determined. Afterwards, for seismic hazard analysis, the seismic ...
