this paper is a concise field report of tafresh earthquake of december 19, 1980 which shook the cities of saveh, qom, arak and nearby villages. observations from the earthquake effects on the buildings and the causes of their failures are discussed briefly.

[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 ...

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...

The 2014 Ms 6.5 (Mw6.1) Ludian earthquake occurred in the eastern Sichuan-Yunnan border region of western China. This earthquake caused much more severe engineering damage than the usual earthquakes with the same magnitude in China. The National Strong Motion Network obtained large set of ground motion recordings during the earthquake. To investigate the engineering interested characteristics o...

background: short golden time is important to save the injured in earthquake and to start search and rescue (sar) operation as soon as possible in affected regions. this study evaluated application of geographic information system (gis) for sar operation in rigan town, kerman province, which was hit by an earthquake of 6.3 richter scale on december 12, 2010 at 22:12. materials and methods: a gi...

The capabilities and advantages of laser scanners used for structural engineering applications to monitor and assess structural damage in laboratory tests and post-earthquake field survey are discussed. High definition laser scans have many advantages over conventional instrumentation as follows: (1) they capture three dimensional global deformations of large objects with accuracy, (2) they all...

an earthquake was happened on 23 october 2011 in van, turkey (mw7.2) at the eastern most area of anatolian plateau and in the neighborhood of iranian border (west azerbaijan province). the study was performed based on field and office observations and has been focused on the process of disaster management in turkey after the 23 october 2011 earthquake. we surveyed the quake from the view point ...

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...

The residential earthquake insurance of 2002 created additional protected residential earthquake insurance plan, under which residential earthquake insurance is available to individuals from insurance industry in Taiwan. Earthquake damages that occurrence in Taiwan remain largely uninsured losses despite the efforts of governmental and private insurance programs. Spatial Econometrics has been r...

The pattern of energy release during the Imperial Valley, California, earthquake of 1940 is studied by analyzing the El Centro strong motion seismograph record and records from the Tinemaha seismograph station, 546 km from the epicenter. The earthquake was a multiple event sequence with at least 4 events recorded at El Centro in the first 25 seconds, followed by 9 events recorded in the next 5 ...
