“…The rupture velocity is generally less than that of the P-and S-waves [11]. The average rupture velocity for the 2010 Yushu earthquake is estimated to have been 3.25 km/s for a 16 s rupture process [21].…”

“…Liquefaction caused by large-magnitude earthquakes has been responsible for a tremendous amount of damage to buildings and infrastructure, including roads [6]- [11]. Liquefaction, induced by an earthquake in non-cohesive soil and sand layers, is generally generated by the horizontal vibration of S-waves, which causes increased pore pressures and which induces effective stresses [4] [12] [13].…”

The 2010 Mw 6.9 Yushu earthquake produced a ~33-km-long co-seismic surface rupture zone along the pre-existing active Yushu Fault on China's central Tibetan Plateau. Sand boils occurred along the tension cracks of the co-seismic surface rupture zone, and locally spouted up above the ground to coat the top of limestone blocks that had slid down from an adjacent ~300-m-high mountain slope. Based on our observations, the relations between the arrival times of P-and S-waves at the sand-boil location and the seismic rupture velocity, we conclude that 1) the sand boils occurred at least 18.24 s after the main shock; 2) it took at least 4.09 -9.79 s after the formation of co-seismic surface rupture to generate liquefaction at the sand-boil location; 3) the spouting height of sand boils was at least 65 cm. Our findings help to clarify the relationships between the timing of liquefaction and the spouting height of sand boils during a large-magnitude earthquake.

“…The incidents of liquefaction phenomena were mainly observed in inland alluvial areas and along coastal areas inducing damage to ports and industrial facilities but some occurred in the free field away from the structures (Sonmez et al 2008). The Chi-Chi earthquake (Taiwan) occurred in 1999 and induced the damages and collapses of bridges, port facilities and buildings.…”

“…The Chi-Chi earthquake (Taiwan) occurred in 1999 and induced the damages and collapses of bridges, port facilities and buildings. According to Yuan et al (2003) among the 39 districts of the city of Yuanlin the 17 were found to have suffered significant settlement and 8 were found to have obvious liquefaction evidence such as sand boils (Sonmez et al 2008).…”

An issue that should be taken into account by urban planners in Greece, for the extension of urban areas, is the likelihood of earthquake-induced ground deformations. In this paper, information is provided regarding the methodology that is applied for the prediction of liquefaction manifestations in urban environment. In particular, a review of our research concerning the evaluation of the probability of liquefaction-induced ground disruption in three towns, Larissa, Edessa and Lefkada, is presented. The evaluation of probability was achieved using the Liquefaction Potential Index methodology and the relatively classification, introduced in late 80's and modified by Papathanassiou (2008).

“…One of the most dramatic contributors of damage to the pile foundation of buildings, bridges, and waterfront structures in several major earthquakes has been the development of liquefaction in deposits of loose sand (Sugimura et al, 2004;Audemard M. et al, 2005;Sonmez et al, 2008;Dash et al, 2009;Palermo et al, 2011;Yen et al, 2011;Wotherspoon et al, 2012).…”

During earthquakes, the response of pile foundations in liquefiable sand reinforced by densification techniques is still a very complex dynamic soil-structure interaction problem. Two shake-table experiments were conducted to investigate the behavior of a reinforced concrete (RC) low-cap pile group embedded in liquefiable soils. Discussion is focused on the behavior of soil-pile-superstructure systems prior to and during liquefaction of the medium-dense and dense sand stratums, which are involved in restoring force characteristics at the superstructure and pile group effect. The test results demonstrated a stiffness reduction and dependent nonlinear behavior appearing in the liquefied medium-dense sand; however, an overall stiffening response was observed in liquefied dense sand. The pile group effect seemed insignificant in liquefied medium-dense sand, but was very significant in the liquefied dense sand.
