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...

We apply the simultaneous detection/discrimination method to the mechanisms mediating detection of longand middle-wavelength test lights. The results suggest the following: (1) a test light detected by a signal initiated primarily in the long-wavelength receptors will be ultimately detected by different sets of nerve cells, depending upon the background illumination. (2) The discriminability of...

This paper begins with a historical review of flashing lights and physical measurement of flashing lights since the time the Blondel-Rey equation was developed. Then the recent work on the physical measurement standards for flashing lights, developed in 1997 at the National Institute of Standards and Technology, is introduced. The paper also discusses the physical requirements and practical asp...

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...
