The exact Cagniard-de Hoop solut ions for a point dislocation in half-space are used to construct models of the strong ground motion observed during the February 9, 1971 San Fernando earthquake (PC, = 6.4). By summing point dislocations distr ibuted over the fault plane, three-dimensional models of a f inite fault located in a half-space are constructed to study the ground motions observed at J...

ABSTRACT Near-field ground motion is the major blind spot of seismic hazard studies, mainly because challenges in accounting for source effects. Initial stress heterogeneity an important component physics-based approaches to ground-motion prediction that represents effects through dynamic earthquake rupture modeling. We hypothesize on a fault primarily originates from past background seismicity...

[1] In a previous paper [Bouchon et al., 2001], we presented what we believe are strong indications of supershear rupture over parts of the faults of the 1999 Turkey earthquakes. These findings are based on near-fault recordings and modeling of the ground motion. We also showed that the supershear value inferred for the Izmit earthquake (the only event for which this velocity is well resolved) ...

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

Batubesi Dam which is located in Sorowako region in the middle part of Sulawesi island had been designed with seismic coefficient about 0.20g. The region constitutes an active earthquake zone with the recurrence frequency and magnitude of the earthquake are relatively high. The region is located on and active fault zone due to lateral fault movement (strike-slip) of Matano fault, Palukoro fault...

We modeled the source rupture process of the 20 September 1999 ChiChi, Taiwan, earthquake (Mw 7.6) using an integrated dataset of near-field strong ground motion and Global Positioning System observations. This large inland thrust earthquake produced a surface break more than 80 km long along the Chelungpu fault. The event triggered over 700 strong-motion instruments on the island of Taiwan. Th...
