Lake Danao (Leyte)
Lake Danao is a guitar-shaped lake on the island of Leyte in the Philippines. The lake is covering an area of . It is situated in the Lake Danao Natural Park, which also includes the Amandiwin mountain range. The lake is northeast of Ormoc, half an hour drive along the San Pablo - Tongonan and Milagro - Lake Danao roads. It was originally named ''Lake Imelda'' and was declared a national park on June 2, 1972 by virtue of presidential memorandum issued by then President Ferdinand Marcos. Later it was renamed and declared as ''Lake Danao National Park'' on February 3, 1998 through ''Proclamation No. 1155'' and is now protected by ''Republic Act No. 7586'' otherwise known as the ''National Integrated Protected Area System (NIPAS) Act of 1992''. The lake supplies potable water to at least seven towns in Eastern Leyte including Tacloban [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyte
Leyte ( ) is an island in the Visayas group of islands in the Philippines. It is eighth-largest and sixth-most populous island in the Philippines, with a total population of 2,626,970 as of 2020 census. Since the accessibility of land has been depleted, Leyte has provided countless number of migrants to Mindanao. Most inhabitants are farmers. Fishing is a supplementary activity. Rice and corn (maize) are the main food crops; cash crops include coconuts, abaca, tobacco, bananas, and sugarcane. There are some manganese deposits, and sandstone and limestone are quarried in the northwest. Politically, the island is divided into two provinces: (Northern) Leyte and Southern Leyte. Territorially, Southern Leyte includes the island of Panaon to its south. To the north of Leyte is the island province of Biliran, a former sub-province of Leyte. The major cities of Leyte are Tacloban, on the eastern shore at the northwest corner of Leyte Gulf, and Ormoc, on the west coast. Leyte to ...

Tagaytay
Tagaytay, officially the City of Tagaytay ( fil, Lungsod ng Tagaytay), is a 2nd class component city in the province of Cavite, Philippines. According to the 2020 census, it has a population of 85,330 people. It is one of the country's most popular destinations for domestic tourism because of its scenery and cooler climate provided by its altitude. Tagaytay overlooks Taal Lake in Batangas and provides views of Taal Volcano Island in the middle of the lake through various vantage points situated in the city. Tagaytay is relatively close to the capital city of Manila, only away via Aguinaldo Highway, providing an easy escape for the locals from the heat of the huge metropolis. It is from Imus. Etymology Legend has it that the word Tagaytay came from "tagâ" meaning to cut and "itáy" which means father. A father and son were said to be on a wild boar hunt when the animal they were chasing turned and attacked them. As the boar charged towards the old man, the son cried "Tagâ ...

Natural Parks Of The Philippines
This is a list of protected areas of the Philippines administered by the Department of Environment and Natural Resources (DENR)'s Biodiversity Management Bureau under the National Integrated Protected Areas System (NIPAS) Act of 1992. As of 2020, there are 244 protected areas in the Philippines covering a total area of about – 15.4% of the Philippines' total area. History The first important legislation that formed the basis of the current system of national parks and protected areas in the Philippines is Act No. 648, enacted in 1903 by the Philippine Commission. This act authorized the civil governor to "reserve for civil public purposes, and from sale or settlement, any part of the public domain not appropriated by law for special public purposes." A total of eight national reserves had been established on July 26, 1904, pursuant to this law. These are the Lamao Forest Reserve in Bataan, Mariquina Reserve in Rizal, Angat River Reserve in Bulacan, Caliraya Falls Reserv ...

Lakes Of The Philippines
The origin of most of the lakes in the Philippines is closely related to volcanic and tectonic activity. A number of smaller lakes occupy the craters of extinct volcanoes. Some lake basins are developed by subsidence due to tectonic or volcanic activity. Others owe their existence to obstruction of drainage courses by landslides, lava flows and by fragmental volcanic ejecta. Among the lakes which are known in the Philippines only three, namely, Laguna de Bay in Luzon, Taal Lake in Luzon, and Lake Lanao in Mindanao, stand out prominently because of their size or economic importance.

OpenStreetMap
OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor. In 2004, OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public and under free licences. Initially, maps were created only via GPS traces, but it was quickly populated by importing public domain geographical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Slash-and-burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom. Slash-and-burn is a type of shif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornbills
Hornbills (Bucerotidae) are a family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a casque on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia. In the Neotropical realm, toucans occupy the hornbills' ecological niche, an example of convergent evolution. De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Philippine Fault System
The Philippine Fault System is a major inter-related system of geological faults throughout the whole of the Philippine Archipelago, primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt. Some notable Philippine faults include the Guinayangan, Masbate and Leyte faults. Philippine Mobile Belt The Philippine Mobile Belt is composed of a large number of accretionary blocks and terranes. These terranes are long and narrow like the Zambales ophiolites which is at least 400 km long and 50 km wide. The strips generally run north–south and the zones of convergence are usually demarcated by fault lines. The Philippine Mobile Belt is compressed on the west by the Eurasian Plate and two arms of the Sunda Plate, and on the east by the Philippine Sea Plate. These tectonic plates have compressed and lifted parts of the Philippines causing extensive faulting, primarily on a north–south axis. All faults in the P ...
