Lake Tikub
Lake Tikub (also known as Lake Ticub, Lake Ticob, Lake Tikob or Lake Ticab) is a nearly circular crater lake located in the province of Quezon, in the Philippines. The circumference of the lake is elevated and thick with foliage that steeply slopes down to the shore of the lake. The lake is located at the foot of Mount Malepunyo, and nearby is Mount Banahaw, in Brgy. Ayusan, in the town of Tiaong. Access to the lake is through Brgy. San Pedro.Borgy"Tiaong Map". Tiaong Quezon Web Site. Retrieved on 2011-01-14. Geology Lake Tikub is a maar or a low-profile volcano created by phreatomagmatic eruption or the interaction between groundwater and magma underneath the Earth's surface. Like the seven lakes in the city of San Pablo, Laguna, which is about away, the lake is one of the monogenetic volcanoes located in the Laguna Volcanic Field.

Luzon
Luzon (; ) is the largest and most populous island in the Philippines. Located in the northern portion of the Philippines archipelago, it is the economic and political center of the nation, being home to the country's capital city, Manila, as well as Quezon City, the country's most populous city. With a population of 64 million , it contains 52.5% of the country's total population and is the fourth most populous island in the world. It is the 15th largest island in the world by land area. ''Luzon'' may also refer to one of the three primary island groups in the country. In this usage, it includes the Luzon mainland, the Batanes and Babuyan groups of islands to the north, Polillo Islands to the east, and the outlying islands of Catanduanes, Marinduque and Mindoro, among others, to the south. The islands of Masbate, Palawan and Romblon are also included, although these three are sometimes grouped with another of the island groups, the Visayas. Etymology The name ''Luz ...

Phreatomagmatic
Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water. They differ from exclusively magmatic eruptions and phreatic eruptions. Unlike phreatic eruptions, the products of phreatomagmatic eruptions contain juvenile (magmatic) clasts.Heiken, G. & Wohletz, K. 1985. Volcanic Ash. University of California Press, Berkeley It is common for a large explosive eruption to have magmatic and phreatomagmatic components. Mechanisms Several competing theories exist as to the exact mechanism of ash formation. The most common is the theory of explosive thermal contraction of particles under rapid cooling from contact with water. In many cases the water is supplied by the sea, for example with Surtsey. In other cases the water may be present in a lake or caldera-lake, for example Santorini, where the phreatomagmatic component of the Minoan eruption was a result of both a lake and later the sea. There have also been examples of interaction between magma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Maars Of The Philippines
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''

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] |
Lucena, Philippines
Lucena, officially the City of Lucena ( fil, Lungsod ng Lucena), is a 1st class Cities of the Philippines#Legal classification, highly urbanized city in the Calabarzon region of the Philippines. It is the capital city of the Provinces of the Philippines, province of Quezon Province, Quezon where it is geographically situated but, in terms of government and administration, the city is politically independent from the province. For statistical and geographical purposes, Lucena is grouped with the province of Quezon Province, Quezon. According to the 2020 census, it has a population of 278,924 people. History Early history In the 1570s, Captain Juan de Salcedo first explored what was then Kalilayan, later founded as a province in 1591. The Order of Friars Minor, Franciscan priests Juan de Plasencia and Diego de Oropesa between 1580 and 1583 founded its town, also named Tayabas.

Laguna Volcanic Field
The Laguna Volcanic Field, also known as the San Pablo Volcanic Field, is an active volcanic field in the Philippines, located between Laguna de Bay, Mount Banahaw volcano complex and Mount Malepunyo range. It is part of the larger Southwestern Luzon Volcanic Field (SWLVF). From Manila, it is about southeast to Mount Makiling, its most prominent volcanic feature. The field is composed of over 200 dormant and monogenetic maars, crater lakes, scoria cones, and stratovolcanoes, the tallest of which is Mount Makiling at in elevation. Many of the maars are aligned along a NE-SW trend. Three generations of maars are present, with the oldest being sediment-filled, like the ones found in Calauan. The youngest maars contain deep lakes with many concentrated in the city of San Pablo. The youngest maar, wide Sampaloc Lake was formed about 500–700 years ago according to local legend, the last major activity in the volcanic field. Volcanism is still evident through the pr ...

Monogenetic Volcano
A monogenetic volcanic field is a type of volcanic field consisting of a group of small monogenetic volcanoes, each of which erupts only once, as opposed to polygenetic volcanoes, which erupt repeatedly over a period of time. The small monogenetic volcanoes of these fields are the most common subaerial volcanic landform. Many monogenetic volcanoes are cinder cones, often with lava flows, such as Parícutin in the Michoacán-Guanajuato volcanic field, which erupted from 1943 to 1952. Some monogenetic volcanoes are small lava shields, such as Rangitoto Island in the Auckland volcanic field. Other monogenetic volcanoes are tuff rings or maars. A monogenetic field typically contains between ten and a hundred volcanoes. The Michoacán-Guanajuato field in Mexico contains more than a thousand volcanoes and is exceptionally large. Monogenetic fields occur only where the magma supply to the volcano is low or where vents are not close enough or large enough to develop plumbing systems f ...

Seven Lakes Of San Pablo
The Seven Lakes of San Pablo ( fil, Pitong Lawa ng San Pablo) are seven volcanic crater lakes scattered around the City of San Pablo, in the province of Laguna, Philippines. The Lakes The seven lakes of the city are: * Lake Bunot * Lake Calibato, sometimes spelled as Lake Kalibato *The twin lakes of Yambo and Pandin * Lake Palakpakin, sometimes spelled as Lake Palacpaquin or Palacpaquen * Lake Muhikap, also known as Lake Mojicap or Lake Mohicap *Lake Sampaloc, also spelled as Lake Sampalok, the largest of the seven lakes Geology The lakes are maars or low-profile volcanic craters located in the San Pablo Volcanic Field. They are among the 200 small monogenetic volcanoes found along the Macolod Corridor, a rift zone between Mount Makiling and Mount Banahaw, which is part of the larger Southwestern Luzon Volcanic Field. These craters are formed by phreatomagmatic eruptions, an eruption where ground water comes in contact with hot magma pushing up near the Earth's surface. Pet ...

Barangay
A barangay (; abbreviated as Brgy. or Bgy.), historically referred to as barrio (abbreviated as Bo.), is the smallest administrative division in the Philippines and is the native Filipino term for a village, district, or ward. In metropolitan areas, the term often refers to an inner city neighborhood, a suburb, or a suburban neighborhood or even a borough. The word ''barangay'' originated from ''balangay'', a type of boat used by a group of Austronesian peoples when they migrated to the Philippines. Municipalities and cities in the Philippines are politically subdivided into barangays, with the exception of the municipalities of Adams in Ilocos Norte and Kalayaan in Palawan, with each containing a single barangay. Barangays are sometimes informally subdivided into smaller areas called ''purok'' ( en, "wikt:zone, zone"), or barangay zones consisting of a cluster of houses for organizational purposes, and ''sitios'', which are territorial enclaves—usually rural—far from t ...

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 ...

Mount Banahaw
Mount Banahaw (; also spelled as Banahao and Banájao) is an active complex volcano on Luzon in the Philippines. The three-peaked volcano is located at the boundary of Laguna and Quezon provinces. It is the highest mountain in both provinces and Calabarzon region, dominating the landscape for miles around. The mountain is considered by many as a holy mountain, thus a ''bundok dambana'', and is popular among pilgrims along with mountain climbers. It is located in a protected area known as Mounts Banahaw–San Cristobal Protected Landscape covering of land. Physical characteristics The andesitic Banahaw volcanic complex is composed of several stratovolcanoes with Mount Banahaw, the largest with a maximum elevation of above mean sea level. The summit is topped by a and deep crater that is breached on the southern rim believed to have been caused by the 1730 eruption. Prior to 1730, a lake occupied the summit crater of Mount Banahaw. The resulting flood destroyed the town ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
