2002 Mindanao Earthquake
The 2002 Mindanao earthquake struck the Philippines at 05:16 Philippine Standard Time on March 6 (21:16 Coordinated Universal Time on March 5). The world's sixth most powerful earthquake of the year, it registered a magnitude of 7.5 and was a megathrust earthquake. It originated near the Cotabato Trench, a zone of deformation situated between the Philippine Sea Plate and the Sunda Plate, and occurred very near to the Philippines' strongest earthquake for the 20th century, the 1918 Celebes Sea earthquake. The entire country is characterized by a high level of volcanic and seismic activity. The earthquake was responsible for 15 deaths and roughly 100 injuries. Up to 800 buildings were damaged as a result, many from a flood generated by landslides and falling debris. Like the 1918 event, a tsunami soon followed. Geology The epicenter of the earthquake was located near the Cotobato Trench; the magnitude of this megathrust earthquake was 7.5, the sixth strongest of the year. It ...

Philippine Standard Time
Philippine Standard Time (PST or PhST; fil, Pamantayang Oras ng Pilipinas), also known as Philippine Time (PHT), is the official name for the time zone used in the Philippines. The country only uses one time zone, at an offset of UTC+08:00, but has used daylight saving time for brief periods in the 20th century. Geographic details Geographically, the Philippines lies and 126°34′ east of the Prime Meridian, and is physically located within the UTC+08:00 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Philippines shares the same time zone with China, Taiwan, Hong Kong, Macau, Malaysia, Singapore, Western Australia, Brunei, Irkutsk, Central Indonesia, and most of Mongolia. History Philippine Standard Time was instituted through Batas Pambansa Blg. 8 (that defined the metric system), approved on December 2, 1978, and implemented on January 1, 1983.

Tectonic Plate
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''. Earthquakes, volcanic activity, mountain-building, and oceanic tren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Parker (Cotabato)
Mount Mélébingóy, formerly known as Parker Volcano, is an active volcano on Mindanao island in the Philippines (6°06.8' N, 124°53.5' E). It is located in the province of South Cotabato, west of General Santos City and south of Koronadal City. The volcano's English name is taken from an American, General Frank Parker, who spotted the mountain and claimed to have "discovered" it during a flight he piloted in 1934. Parker led an expedition up to the lake in the mountain's crater with other US colonial and Filipino government officials, including Vice-Governor-General Joseph Ralston Hayden and Provincial Governor Gutierrez, in the fall of 1934.J.

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Sulu Trench
The Sulu Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Mindanao and Sulu in the Philippines. The trench reaches a depth of about 5,600 metres (18,400 ft), in contrast with the average depth of the South China Sea of about 1,500 metres (4,900 ft). The trench formed when the Sunda Plate (part of the Eurasian Plate) subducts below the Philippine Mobile Belt. The convergent boundary terminates at the Negros Trench in the east. The Sulu Trench is not associated with frequent earthquakes, but hosts volcanoes south of the trench such as Mount Malindang. Background The Sulu 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 8–9 million years ago, This trench is located southeast of the Visayan Islands, The rate ...

Manila Trench
The Manila Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Luzon and Mindoro in the Philippines. The trench reaches a depth of about , in contrast with the average depth of the South China Sea of about . It is created by subduction, in which the Sunda Plate (part of Eurasian Plate) is subducting under the Philippine Mobile Belt, producing this almost N-S trending trench. The convergent boundary is terminated to the north by the Taiwan collision zone, and to the south by the Mindoro terrane (Sulu-Palawan block colliding with SW Luzon). It is an area pervaded by negative gravity anomalies. The Manila Trench is associated with frequent earthquakes, and the subduction zone is responsible for the belt of volcanoes on the west side of the Philippine island of Luzon, which includes Mount Pinatubo. Convergence between the Philippine Mobile Belt and the Sunda Plate have been estimated using GPS measurements, and this value ranges from ~ 50+ mm/yr in T ...
