Most seismic codes specify empirical formulas to estimate the fundamental vibration period of buildings. Evaluated first in this paper are the formulas specified in present US codes using the available data on the fundamental period of buildings “measured” from their motions recorded during eight California earthquakes, starting from the 1971 San Fernando earthquake and ending with the 1994 Nor...

In this study, for supporting global rescue operations, we will propose a new earthquake damage detection method, based on a combination of earthquake damage estimation using earthquake information (magnitude, location of source, detailed ground condition, and attenuation equation for distance) and change detection by means of remote sensing data. First, to find collapsed buildings and houses o...

Remote sensing technology is playing an increasingly important role in post-disaster decision support. Organizations including the Earthquake Engineering Research Institute (EERI) and Multidisciplinary Center for Earthquake Engineering Research (MCEER) recognize that following major earthquakes, satellite imagery can bring significant benefits to response and recovery efforts, through urban dam...

In order to use science to manage human–nature interactions, we need much more nuanced, and when possible, quantitative, analyses of the interplay among ecosystem services (ES), human well-being (HWB), and drivers of both ecosystem structure and function, as well as HWB. Despite a growing interest and extensive efforts in ES research in the past decade, systematic and quantitative work on the l...

A prominent long-period wave with a duration of 2000 sec or longer was recorded with a very-broadband system in Pasadena on June 18, 1988. This wave was not observed elsewhere, and i s considered of local origin. The acceleration amplitude is 2.5x10 -5 cm/sec 2 in the northwest direction, with the vertical component less than 10% of the horizontal. The horizontal acceleration can be interpreted...
