List Of Disasters In The Philippines
This is a list of disasters in the Philippines. Astronomical phenomenon Pre-history Historical era Volcanic eruptions Pre-history * Most of the eruptions recorded from potentially active stratovolcano according to Rev. Andrei John Apostol, PhD, CPA. * Historical era Earthquakes Pre-history * There are no recorded of events nor few about earthquake before the History was written, but it would be possibly caused by collision of Tectonic Plates and Volcanic Eruptions, resulting to earthquakes, and forming mountains, volcanoes and even lakes. *For example, the Taal Volcano, this is a part of a chain of volcanoes along the island of Luzon, which were formed by two tectonic plates colliding over 500,000 years ago. Since the formation of this large caldera, subsequent eruptions created another volcanic island, within Taal Lake, known as Volcano Island. Historical era The table below is a tally of the ten most deadly recorded earthquakes in the Philippines since the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary Extinction Event
The Quaternary period (from 2.588 ± 0.005 million years ago to the present) has seen the extinctions of numerous predominantly megafaunal species, which have resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe. The most prominent event in the Late Pleistocene is differentiated from previous Quaternary Turnover-pulse hypothesis, pulse extinctions by the widespread absence of ecological succession to replace these extinct species, and the regime shift of previously established faunal relationships and habitats as a consequence. The earliest casualties were incurred at Eemian, 130,000 BCE (the Eemian, start of the Late Pleistocene), in Australia (continent), Australia ~ 60,000 years ago, in Americas ~ 15,000 years ago, coinciding in time with the early human migrations. However, the great majority of extinctions in Afro-Eurasia and the Americas occurred during the transition from the Pleistocene to the Holocene epo ...

Pampanga River
The Pampanga River is the second largest river on the island of Luzon in the Philippines (next to Cagayan River) and the country's fifth longest river. It is in the Central Luzon region and traverses the provinces of Pampanga, Bulacan, and Nueva Ecija. Topography Its headwaters are at the Sierra Madre and runs a south and southwesterly course for about until it drains into Manila Bay. The river's basin covers an area of , including the allied basin of Guagua River. The basin is drained through the Pampanga River and via the Labangan Channel into the Manila Bay. Its main tributaries are Peñaranda and the Coronel-Santor rivers on the eastern side of the basin and the Rio Chico River from the northwest side. The Angat River joins the Pampanga River at Calumpit, Bulacan via the Bagbag River. Mount Arayat (elevation: ) stands in the middle of the basin. Southeast of Mount Arayat and the Pampanga River is the Candaba Swamp, covering an area of some absorbing most of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to ...

2050 BC
The 21st century BC was a century that lasted from the year 2100 BC to 2001 BC. Events Note: all dates from this long ago should be regarded as either approximate or conjectural; there are no absolutely certain dates, and multiple competing reconstructed chronologies, for this time period. * c. 2150 – 2040 BC – The First Intermediate Period of Egypt, a period of decline in Egyptian central power. * c. 2112 – 2004 BC – The Third Dynasty of Ur. Administrative power in Ur is pushed far, with an Ensi, an appointed civil servant, at the head of the constituencies. A meticulous and finicky bureaucracy manages, counts and controls the whole administration, which is as much concerned with the economy as with war or the service of the gods. The weight of such an administration arguably contributed to the collapse of the empire. The documentation of the Third Dynasty of Ur does not attest to the existence of private property, but rather a state organization of agricultural pro ...

Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained ( aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene ( augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites. The relative proportions of feldspars a ...

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Geology of Mars, Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Pinatubo
Mount Pinatubo is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon. Its eruptive history was unknown to most before the pre-eruption volcanic activity of early 1991. Pinatubo was heavily eroded and obscured from view by dense forests which supported a population of several thousand indigenous Aetas. Pinatubo is most notorious for its VEI-6 eruption on June 15, 1991, the second-largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta in Alaska. Complicating the eruption was the arrival of Typhoon Yunya, bringing a lethal mix of ash and rain to towns and cities surrounding the volcano. Predictions at the onset of the climactic eruption led to the evacuation of tens of thousands of people from the surrounding areas, saving many lives. Surrounding areas were severely damaged by pyroclastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Talinis
Mount Talinis is a complex volcano in the Philippines, Philippine Provinces of the Philippines, province of Negros Oriental.

Mount Malinao
Mount Malinao is a potentially active stratovolcano located in the Bicol Region of the Philippines. The volcano displays strong fumarolic activity which is harnessed for generating electricity. Located on its slope is Tiwi Geothermal Power Plant, one of the first geothermal energy plant commissioned in the country. Location Malinao Volcano is situated between the provinces of Albay and Camarines Sur in the southeastern region of Luzon Island; about north-northwest of Mayon volcano, the most active volcano in the Philippines. Physical features The mountain is forested with an elevation of above sea level and a base diameter of . On the summit of the volcano is a large crater with bare inner walls that are breached on the eastern side. On the lower flank this side of the predominantly andesitic volcano, is Luzon's largest solfataras and hot springs, some of which deposit siliceous sinter. Naglagbong and Jigabo are two thermal wells located on the volcano. Temperatures up to were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laguna Caldera
Laguna Caldera is a potentially active volcanic caldera and a geographical depression in Rizal, Philippines. It is broadly elliptical in shape, with dimensions of 20 by 10 km. It has a summit elevation of 743 m or 2,438 feet. The caldera forms the middle lobe of Laguna de Bay, bound by the Morong Peninsula and Talim Island to the west, and the Jalajala Peninsula to the east. The caldera may have formed in two stages about 1 million and 27,000-29,000 years ago, during which time at least two major explosive eruptions took place. It is unknown when the Laguna Caldera last erupted but it may have been active during the Holocene. Deposits from the caldera form thick ignimbrite sheets in Rizal, Metro Manila, Laguna, and Bulacan. Remnants of volcanic activity include undated maars at the southern end of Talim Island and a solfatara field on nearby Mount Sembrano. Given the current shape of the lake and the caldera, and how it was once connected to Manila Bay as evidenced by its gro ...
