Modern strong‐motion accelerometers record instruments’ translational accelerations as well as their rotation. Based on a detailed analysis of the low‐frequency content of acceleration records, Javelaud et al. (2011) removed the permanent tilt

Water pressure changes have been recorded during the 2011 Tohoku earthquake (Mw9.0) by two oceanbottom pressure gauges of the JAMSTEC cabled observatory located approximately 400 km north of the tsunami source. In the present study, observed water pr

The translational accelerations recorded by strong-motion seismometers are often contaminated by baseline offsets that prevent recovering theground displace- ments by double integration. Detailed analysis of the K-NET95 strong-motion seis- mometer, a

The 2007 Noto Hanto earthquake (Mj 6.9) occurred off northwest of Noto Peninsula, Japan on March 25, 2007, associated with a tsunami. A tsunami excited due to fault movement was well calculated by the tsunami simulation method with static displacemen

This paper presents a simulation of the 2003 Tokachi-oki Earthquake (M8.0) by using 3-dimensioinal dynamic tsunami simulation. In this simulation, we used three types of fault models; these were determined by inversion of teleseismic body wave, groun
