This paper describes the results of an extensive study on the seismic behavior of a structure with damper and without damper under different earthquake acceleration frequency like Earthquake Altadena, Earthquake Lucerne and Earthquake New Hall. It is observed through nonlinear time history analysis that maximum displacement, maximum base shear and maximum acceleration can be effectively reduced...

INTRODUCTION The aim of the study was to study the long-term effect on cardiovascular disease risk factors of stress from direct experience of an earthquake as a young person. MATERIAL AND METHODS We selected workers born between July 1, 1958 and July 1, 1976 who were examined at Kailuan General Hospital between May and October of 2013. Data on cardiovascular events were taken during the work...

BACKGROUND After the East Japan Earthquake disaster there may have been a deterioration of patients with cardiovascular diseases. METHODS AND RESULTS We examined the data from 189 consecutive patients implanted with cardiovascular devices for the 6-month period before and after the Earthquake. In 170 patients with defibrillators, the number who experienced tachyarrhythmias increased significa...

We describe the findings on the current state and challenges of pediatric psychiatry in Fukushima prefecture following the Great East Japan Earthquake. When examining the time elapsed after the earthquake, there is an impression that psychiatric problems become apparent in the early period after the earthquake in mothers who had demonstrated vulnerability in development and nurturing before the...

[1] Using the example of the 1992 M 7.3 Landers earthquake, we show that in the aftermath of a large earthquake the depth extent of aftershocks shows an immediate deepening from pre-earthquake levels, followed by a time-dependent postseismic shallowing. We use these seismic data to constrain the change in the depth of the seismic-aseismic transition with time throughout the earthquake cycle. Mo...

BACKGROUND Christchurch, New Zealand, was struck by 2 major earthquakes at 4:36 am on 4 September 2010, magnitude 7.1 and at 12:51 pm on 22 February 2011, magnitude 6.3. Both events caused widespread destruction. Christchurch Hospital was the region's only acute care hospital. It remained functional following both earthquakes. We were able to examine the effects of the 2 earthquakes on acute ca...

The tectonically complex San Francisco Bay Region (SFBR) contains both known and unidentified faults that produce a broad range of earthquake sizes at different rates of occurrence. In this chapter we use fault zone information developed in the previous chapter to construct an earthquake source model that describes long-term rates of earthquake production in the SFBR. Specifically, this SFBR ea...

Post-traumatic stress, depression and anxiety symptoms are common outcomes following earthquakes, and may persist for months and years. This study systematically examined the impact of neighbourhood damage exposure and average household income on psychological distress and functioning in 600 residents of Christchurch, New Zealand, 4-6 months after the fatal February, 2011 earthquake. Participan...

After the May 12, 2008 earthquake in Wenchuan, Sichuan, suspicion grew among Earth scientists that the Zipingpu Dam reservoir had triggered the devastating earthquake, which killed more than 80,000 Chinese citizens. Since then, some 50 to 60 articles and studies have investigated this massive seismic event and its relationship to the Zipingpu reservoir. This paper reviews the literature and con...
