Selection of earthquake ground motions is considered with the goal of accurately estimating the response of a structure at a speci ed ground motion intensity, as measured by spectral acceleration at the rstmode period of the structure, Sa(T1). Consideration is given to the magnitude, distance and epsilon ( ) values of ground motions. First, it is seen that selecting records based on their value...

High-amplitude seismic waves from the Mw 7.0 Kumamoto earthquake of April 16, 2016, triggered another large earthquake 80 km to the NE roughly 30 s later. The source was located at shallow depths beneath the Yufuin geothermal field, Oita Prefecture, Japan, and the event magnitude was approximately 5.9. To date, this is one of the clearest known examples of a remotely triggered large earthquake....

Earthquake DSS is an information technology environment which can be used by government to sharpen, make faster and better the earthquake mitigation decision. Earthquake DSS can be delivered as E-government which is not only for government itself but in order to guarantee each citizen’s rights for education, training and information about earthquake and how to overcome the earthquake. Knowledge...

Large-scale disasters have immeasurable effects on human and animal communities. Evaluating and reporting on the response successes and difficulties encountered serves to improve existing preparedness documents and provide support to those in the process of developing plans. Although the majority of disasters occur in low and middle income nations, less than 1% of the disaster literature origin...

Motivated by the Holocene history of great Cascadia earthquakes proposed by Goldfinger et al. (2012), we developed a simple model by which we can examine this further. Combining their observation that the plate boundary ruptures in four characteristic segment types with an empirical area versus seismic moment relation and an assumption of constant stress drop, we obtain a model for the along-st...

We analyzed the IRIS broad-band seismograms for the June 9, 1994, Bolivia earthquake, the largest deep-focus earthquake ever recorded. We inverted the record sections with a duration of 330 sec which include P, pP and sP phases, and obtained a dip-slip mechanism: (dip(fi), rake()0, strike(•)) = (13 ø, 4 ø, 1 ø) or (89 ø, -103ø, ' 95ø), with a scalar moment of Mo--2.9x1021 Nm (Mw-8.2). This mech...

The normal modes spectra of the Earth’s free oscillations contain valuable information on the longest wavelength three dimensional structure of the Earth’s interior. Dahlen (1982) first showed that the optimum record length for measuring eigenfrequencies and decay rates of normal modes using a Hanning taper is 1.1 Q cycles. Since typical modal Q values lie in the range 10 of to 10, optimum wind...

After Aceh’s quake many earthquakes have struck Indonesia alternately and even other disasters have been a threat for every citizen in this country. Actually an everyday occurrence on earth and more than 3 million earthquakes occur every year, about 8,000 a day, or one every 11 seconds in Indonesia there are 5 to 30 quakes prediction everyday. Government’s responsibility to protect the citizen ...

Despite of over a century of scientific effort, the understanding in earthquake forecasting remains immature. Moreover, even the theoretical possibility of earthquake forecasting is debatable. Especially problematic is a possibility of an effective shortand intermediate-term earthquake forecasting. The aim of this paper is to present the new evidence in support of possibility of the shortand in...

— An Earthquake is more important for geophysics and economy problems. The Support Vector Machine of data mining techniques with cluster analysis is used to predict impact of earthquake [2]. The historical data are collected which has follow the time series methodology, combine the data mining for pre-processing and finally apply the SVM to predict the impact of earthquake. Earthquake predictio...
