Strong motion records are the original input data for earthquake engineering studies and earthquake resistant building codes. Records originating from both, analogue and modern digital instruments should be subjected to processing in order to derive credible engineering parameters, such as spectral ordinates. A number of processing procedures have been proposed by many researchers through the p...

We present evidence of land-level change resulting from the 2016 Mw 7.6 Chiloé earthquake tidal wetlands along southern coastline Isla de Chiloé, Chile, to test criteria for detection low-level, <0.1 m, coseismic change. In order record in wetland sediments, both creation and preservation thresholds must be exceeded. High-resolution diatom analyses sediment blocks at two marshes reveal that exc...

This study provides a comparison of results from dynamic centrifuge tests and finite element analysis model to confirm the behavior representative Korean stone pagoda cultural heritage structure against earthquakes. The indirect stiffness or physical state was estimated by measuring natural frequency masonry pagoda. actual measured be 4.5 Hz. It determined have lower than other pagodas similar ...

The simulation of structural and geotechnical systems is a critical step in their design and assessment. The purpose of an earthquake simulation is to estimate the performance of the system under seismic excitation or loads that represent the effects of an earthquake. Structural and geotechnical simulation has a long history of development in earthquake engineering. The computation required to ...

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation type timber–steel structure that incorporates prefabricated light wood-frame shear walls into steel moment-resisting frames (SMRFs). The such was evaluated through sh...

PURPOSE Massive earthquakes are harmful to humankind. This study of a historical cohort aimed to investigate the difference between earthquake-related crush thoracic traumas and thoracic traumas unrelated to earthquakes using a multi-detector Computed Tomography (CT). METHODS We retrospectively compared an earthquake-exposed cohort of 215 thoracic trauma crush victims of the Sichuan earthquak...

Mega quakes pose major threats to modern society, generating casualties and fatalities, disrupting socioeconomic activities, and causing enormous economic loss across the world. Recent major disasters, such as the 2004 Indian Ocean tsunami, the 2011 Tohoku Japan earthquake and tsunami, and the 2015 Gorkha Nepal earthquake, are vivid reminders that complex risk cascades drive most earthquake cri...

An intensive earthquake, the Wenchuan Earthquake of 8.0 on the Richter scale, struck western Sichuan, China on May 12, 2008. The earthquake significantly affected all industries in the quake-hit areas including local tourism. This paper provides suggestions for reconstruction after outlining findings on the various ways by which the earthquake affected the operations and viability of tourism in...

As part of research collaboration between MCEER and the National Center for Research in Earthquake Engineering (NCREE) in Taiwan, a team of MCEER/NCREE researchers undertook a reconnaissance mission shortly after the 921 Chi-Chi earthquake occurred in Taiwan at 1:47 a.m. on September 21, 1999. A major objective of this mission was to assess earthquake-induced damage, to document lessons learned...

Total electron content (TEC) data, obtained from GPS satellites can be used as a tool for extracting earthquake precursor. In this paper, a pattern matching technique is used for monitoring TEC variation during and prior to the earthquake. For the experiment two major earthquake events i.e. Bhutan earthquake on 21st September 2009 and Nepal earthquake on 25th April 2015 are considered for analy...
