A number of seismic response records obtained from instrumented bridge during earthquake provide opportunity to assess structural performance and integrity by evaluating structural dynamic characteristics and its possible changes due to earthquake. In this paper a methodology to identify dynamic characteristics of instrumented bridge based on earthquake-induced vibration is presented. A time do...

We conducted a study to examine the effect of seasonal variations and the disruptive effects of the 2015 Nepal earthquake on microbial communities associated with drinking water sources. We first characterized the microbial communities of water samples in two Nepali regions (Kathmandu and Jhapa) to understand the stability of microbial communities in water samples collected in 2014. We analyzed...

The great Sumatra–Andaman earthquake of 26 December 2004 (UTC 00:58:53) was a momentous event, whether measured by scientific or human standards. Sadly, what is currently regarded as the third largest earthquake in recorded history led to the worst tsunami disaster in recorded history, with the loss of more than 200,000 lives and devastation throughout the Bay of Bengal. About three months late...

elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. these structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. damage to these structures during strong ground motions may lead to fire or other ...

Normally, an earthquake is considered as a phenomenon of wave energy radiation by rupture (fracture) of solid Earth. However, the physics of dynamic process around seismic sources, which may play a crucial role in the occurrence of earthquakes and generation of strong waves, has not been fully understood yet. Instead, much of former investigation in seismology evaluated earthquake characteristi...

The Karmania Hazard Model (KHM) is a GIS-based application for earthquake scenario development and disaster management. The lack of integrated and automated tools for estimating resources needed in the aftermath of an earthquake during the disaster response phase motivated the design and implementation of a comprehensive, interactive, and user-friendly model. This model draws on datasets integr...

In this study, joint inversions of Synthetic Aperture Radar (SAR) and Global Position System (GPS) measurements are used to investigate the source parameters of four Mw > 5 events of the 2016–2017 Central Italy earthquake sequence. The results show that the four events are all associated with a normal fault striking northwest–southeast and dipping southwest. The observations, in all cases, are ...

The state-of-the-art of near-fault problems in earthquake engineering is comprehensive reviewed. Strong ground motions in the near-fault region exhibit several new characteristics, which cause the attentions of both seismologists and engineers who zealously studied these ground motions during the last two deceases. The investigation on ground motions can interpret the mechanism of the earthquak...

b-Value Variations Preceding the Devastating, 1999 Earthquake, near Izmit, Turkey Sara Andersson The potential of temporal b-value variations as an intermediate-term (weeks to months) earthquake precursor was investigated in the western portion of the North Anatolian Fault Zone (NAFZ), between January 1982 to December 2004. The focus of the study is on the devastating, 1999 earthquake, near Izm...
