Negros Trench
The Negros Trench is an oceanic trench located northeast of the Sulu Trench and west of Negros Island Region in Visayas, the trench is located in the Sunda Plate in the southwestern region of the Pacific Ocean. The depth of the Negros Trench is unknown, in contrast it's neighboring trench the Sulu Trench has a depth of 5,600. During the Early-Miocine, the Sunda Plate subducted below the Philippine Mobile Belt, which would later form the Negros Trench. Background The Negros trench was formed from subduction of the Eurasian Plate underneath the Philippine Sea plate which initiated during the Early Miocene (23.03-20.44 million years ago), The trench was previously the site of a collision zone with the Palawan plate, which formed the Philippine Trench The Philippine Trench (also Philippine Deep, Mindanao Trench, and Mindanao Deep) is a submarine trench to the east of the Philippines. The trench is located in the Philippine sea of the western North Pacific Ocean and cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subduction Zones
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the dens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology Of The Philippines
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...

2012 Negros Earthquake
The 2012 Negros earthquake occurred on February 6 at , with a body wave magnitude of 6.7 and a maximum intensity of VII (''Destructive'') off the coast of Negros Oriental, Philippines. The epicenter of the thrust fault earthquake was approximately north of Negros Oriental's provincial capital, Dumaguete. Earthquake The recorded intensities according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) on the Earthquake Intensity Scale (PEIS) were VII in Dumaguete and V in Cebu. The earthquake was felt as far as Mindanao in the provinces of Misamis and Lanao as well as Iligan. Geology The Philippines lies within the Pacific Ring of Fire, which results in the archipelago experiencing frequent volcanic and seismic activity. The strongest earthquake to hit Negros occurred in 1948, but did not cause any damage. According to PHIVOLCS, the earthquake was caused by movement on a previously undiscovered fault.

1990 Panay Earthquake
The 1990 Panay earthquake occurred at 3:41 p.m. local time on 14 June 1990 with a moment magnitude of 7.1 in the Richter scale, leaving eight dead and 41 others injured. The epicenter was located at Culasi, Antique on Panay Island in the Philippines. The depth was computed to be 15 kilometers. It was generated by fault movement in the collisional zone off western Panay Island.
