The respective tectonic effects of back arc spreading and continental collision in Asia are considered either as two independent processes or as closely interrelated. Extrusion tectonics assumes that the opening of the South China Sea and the left-lateral motion along the Red River fault are geometrically linked in a pull-apart manner. This model is not accepted by several workers because the s...

We propose a multi-tiered architecture for middleware-independent Grid job management. The architecture consists of a number of services for well-defined tasks in the job management process, offering complete user-level isolation of service capabilities, multiple layers of abstraction, control, and fault tolerance. The middleware abstraction layer comprises components for targeted job submissio...

Dating of submarine volcanic systems is key to understand the history tectonic and interactions within Lesser Antilles arc. In this study, we investigate radioisotopic dating located between Les Saintes (Guadeloupe) Dominica islands in an intra-arc graben bounded west by active Roseau fault. Submarine lava flows domes have been sampled with remotely operated vehicle (ROV) Victor6000 controlled ...

The fault geometry, depth, and slip distribution of the Kurile earthquake of Oct. 4, 1994 are estimated using seismic waveforms, aftershock distribution, geodetic measurements, and tsunami waveforms. Previous large earthquakes in the Kurile arc had typical underthrusting focal mechanisms due to the local subduction. Seismic wave inversions of the 1994 event indicate a thrust type mechanism with...

Bolaang Mongondow is located on the Eastern North arm of Sulawesi. This area a Neogene-aged magmatic arc composed plutonic and volcanic rocks that indicate mineralization-bearing host rocks. The study aimed to determine geological setting alteration based observations geochemical analysis. method used mapping, followed by laboratory studio data lithology this andesite, diorite, pyroclastic brec...
