Earthquake and its catastrophic failures has been one of the disturbance worry of Civil Engineers. In geotechnical science, liquefaction is one of the most important phenomenons induced by earthquake. A change in pore water pressure follows a change in effective stress, and in a critical state in which pore water pressure equals the total stress in soil particles, soil strength is suddenly lost...

[1] We observe changes in the waveforms of repeating earthquakes in eastern Taiwan following the 1999 Mw7.6 Chi-Chi earthquake, while their recurrence intervals appear to be unaffected. There is a clear reduction in waveform similarity and velocity changes indicated by delayed phases at the time of the Chi-Chi event. These changes are limited to stations in and paths that cross the 70 × 100 km ...

earthquakes could have catastrophic impacts on tunnels and buried structures. liquefaction phenomenon is one of the most destructive effects of earthquakes. liquefaction results in decreasing effective stress and this consequently leads to decreases in shear strength of the soil. as a result, large deformation in both soil and buried structure occurs. moreover, liquefaction causes soil boiling,...

When rainfall and earthquake occur simultaneously, large-scale landslides can cause direct damage to lives structures. To reduce such landslide damage, earthquake-induced susceptibility has be evaluated. Therefore, in this study, was evaluated by considering only rainfall, earthquake, both the Atsuma region of Japan, where a triggered combination earthquake. Through quantitative index analysis,...

The Zagreb 2020 earthquake severely damaged the historic centre of city. Most damage occurred on masonry residential buildings, many which are situated very close to tram track. Although traffic-induced vibrations generally do not affect surrounding they can be harmful buildings by a previous earthquake. Vibrations could contribute further propagation existing cracks. effect depends factors, on...

Soil liquefaction has been observed worldwide during recent major earthquakes with induced effects responsible for much of the damage, disruption of function, and considerable replacement expenses for structures. The phenomenon has not been documented in recent time with such damage in Italian context before the recent Emilia-Romagna Earthquake (May 2012). The main lateral spreading and vertica...

Does Acute Catastrophic Psychological Stress Disrupt Diurnal Cardiovascular Variability? To the Editor: Prof Parati et al1 reported an interesting case in which ambulatory blood pressure (BP) monitoring was performed at the time of an earthquake (4.7 on Richter scale), which demonstrated than acute catastrophic psychological stress can raise BP and heart rate in an ambulatory setting. In a rece...
