Foundations may undergo severe distress during an earthquake. One such example of foundation failure involving toppling of apartment blocks due to liquefaction during the 1964 Niigata Earthquake is presented in Figure 1. Earthquake effects on shallow and deep foundations are accounted for by designing them structurally to provide necessary strength and ensure serviceability. Strength considerat...

[1] The clustering of earthquakes in time on the same fault affects the rate and pattern of interseismic deformation. We develop a simple analytic viscoelastic model of the surface velocity field through a clustered earthquake cycle by superposing the velocities of individual earthquake cycles of constant period but varying phase. Velocity profiles prior to and after an earthquake show a wider ...

In a spirit akin to the sandpile model of selforganized criticality, we present a simple statistical model of the cellular-automaton type which simulates the role of an asperity in the dynamics of a one-dimensional fault. This model produces an earthquake spectrum similar to the characteristic-earthquake behaviour of some seismic faults. This model, that has no parameter, is amenable to an alge...

Earthquake is one of the most commonly happened disasters with devastating consequences and poses significant risks to human society. The ability to determine the time and location of an earthquake can provide valuable information for rescue guidance, hazard assessment and scientific study. After a destructive earthquake, an accurate earthquake location is the most importtance information neede...

Sediments tell a tsunami story Trying to understand where major earthquakes and tsunamis might occur requires analysis of the sediments pouring into a subduction zone. Thick sediments were expected to limit earthquake and tsunami size in the Sumatran megathrust event in 2004, but the magnitude 9.2 earthquake defied expectations. Hüpers et al. analyzed sediments recovered from the Sumatran megat...

An event called prediction in a time series is more important for geophysics and economy problems. The time series data mining is a combination field of time series and data mining techniques. The historical data are collected which has follow the time series methodology, combine the data mining for preprocessing and finally apply the fuzzy logic rules to predict the impact of earthquake. Earth...

One of the prominent problems in wind farms is voltage flicker emission. To prevent emission or mitigate impact as best possible, a static VAr compensator (SVC) great candidate both economically and technically. However, SVCs cannot completely compensate fast-changing reactive power due to delays caused by calculation unit triggering fire angle SVC. This paper proposes predictive control system...

BACKGROUND An earthquake struck Ludian in Yunnan province of China on August 3, 2014, resulting in 3143 injuries, 617 deaths, and 112 missing persons. Our study aimed at estimating the quality of life and associated determinants among medical rescuers after Ludian earthquake. METHODS A cross-sectional survey was performed among personnel from three hospitals that assumed rescue tasks in Ludia...

BACKGROUND Although acute coronary syndrome (ACS) and stroke are known to increase after earthquake, few data exist regarding the effect of earthquake on these cardiovascular events in rural areas. METHODS AND RESULTS The Noto Peninsula earthquake with a magnitude of 6.9 occurred at 9:45 a.m. on 25 March 2007. The first case of ACS occurred approximately 15 min later, whereas cerebral hemorrh...

The long-term evolution of scaling (fractal) characteristics of the ULF geomagnetic fields in the seismoactive region of the Guam Island is studied in relation to the strong (Ms = 8.0) nearby earthquake of 8 August 1993. The selected period covers 10 months before and 10 months after the earthquake. The FFT procedure, Burlaga-Klein approach and Higuchi method, have been applied to calculate the...
