Estimation of the dynamic characteristics of buildings is a key issue in seismic design technology. Since 1957, the Building Research Institute (BRI), Japan, has been operating a network to monitor strong motion in buildings. In this study, dynamic characteristics of 25 actual buildings in the BRI network were estimated by using strong motion records. Acceleration records from two sensors respe...

The Mw 7.8 Gorkha earthquake of 25 April 2015 triggered thousands of landslides in the central part of the Nepal Himalayas. The main goal of this study was to generate an ensemble-based map of co-seismic landslide susceptibility in Sindhupalchowk District using model comparison and combination strands. A total of 2194 co-seismic landslides were identified and were randomly split into 1536 (~70%...

For health monitoring of a building, we need to separate the response of the building to an earthquake from the imprint of soil-structure coupling and from wave propagation below the base of the building. Seismic interferometry based on deconvolution, where we deconvolve the wave fields recorded at different floors, is a technique to extract this building response and thus estimate velocity of ...

SUMMARY An ensemble model integrates forecasts of different models (or parametrizations the same model) into one single forecast. This procedure has names in literature and is approached through philosophies theory practice. Previous approaches often weighted equally or according to their individual skill. Here we present a more meaningful strategy by obtaining weights that maximize skill ensem...

INTRODUCTION On 08 October 2005, an earthquake measuring 7.6 on the Richter scale, struck Pakistan's autonomous state of Kashmir and part of Indian-administrated Kashmir.The official death toll in Pakistan was 79,000, and nearly 1,400 in Kashmir. This study reports the findings of a three-week health needs assessment to understand the needs of rural, older people postearthquake. This study was ...

After the occurrence of an earthquake, the issues such as making decision promptly on building safety, making possibility to keep on utilizing from a building, locating the ruined place and the rate of the destruction is crucial. Today a new technique is the application of evolutionary artificial neural network models based on artificial intelligence, which is widely used in various scientific ...

We present a new method for estimating earthquake detection probabilities that avoids assumptions about earthquake occurrence, for example, the event-size distribution, and uses only empirical data: phase data, station information, and network-specific attenuation relations. First, we determine the detection probability for each station as a function of magnitude and hypocentral distance, using...

During the 2003 Tokachi-Oki tsunamigenic earthquake the real-time JAMSTEC observatory obtained records which provided a unique opportunity to have a look deep inside the tsunami source. Considering water column as a compressible medium we processed the bottom pressure records in order to estimate amplitude, duration and velocity of bottom displacement. Spectral analysis of the records revealed ...

Following the recent establishment of a high-density seismic network equipped with low-cost micro-electro-mechanical system (MEMS) P-wave-alert-device (P-Alert) by the earthquake early warning (EEW) research group at the National Taiwan University, a large quantity of strong-motion records from moderate-magnitude earthquakes (ML > 6) around Taiwan has been accumulated. Using a data preprocessin...
