Japanese drill ship fails to reach the earthquake-generating zone

Why Concatenation Fails Near the Anomaly Zone.

Genome-scale sequencing has been of great benefit in recovering species trees but has not provided final answers. Despite the rapid accumulation of molecular sequences, resolving short and deep branches of the tree of life has remained a challenge and has prompted the development of new strategies that can make the best use of available data. One such strategy-the concatenation of gene alignmen...

Earthquake hazards on the cascadia subduction zone.

Large subduction earthquakes on the Cascadia subduction zone pose a potential seismic hazard. Very young oceanic lithosphere (10 million years old) is being subducted beneath North America at a rate of approximately 4 centimeters per year. The Cascadia subduction zone shares many characteristics with subduction zones in southern Chile, southwestern Japan, and Colombia, where comparably young oc...

Shizuoka Prefecture Disaster Drill Involving the Japanese and US Military.

Izu peninsula is in Shizuoka prefecture, which is approximately 130 km from Tokyo. According to a report from the National Research Institute for Earth Science and Disaster Prevention, Izu peninsula is located just on the border between the Philippine Sea and the Eurasian plate. In this area, huge earthquakes, called Tokai earthquakes, have occurred repeatedly every 100 to 150 years. The next e...

practical engineering approach for generating the torsional earthquake excitation from translational components

worldwide networks of seismic recording instruments mostly record only translational ground motion in two or three orthogonal directions. rotational component of earthquake is not commonly recorded. several theories are available to estimate a torsional component from recorded translational components of ground motion. in this paper detailed investigations are made to study the relative perform...
