Mount Macolod
Mount Macolod (other spelling: Maculot) is a dormant stratovolcano located in the municipality of Cuenca, Batangas in the Philippines. Popular with mountain climbers and campers, it is the main tourist attraction of Cuenca. The mountain is sacred to both Christians and Anitists. Every year on Holy Week, thousands of pilgrims from nearby towns and provinces climb the mountain as a form of penance. Geography The mountain is about tall and is also located adjacent to Taal Lake. Mount Macolod and its high volcanic rock wall called ''The Rockies'' are said to be part of Taal Caldera's crater rim. Geological history Based on studies on Taal, it is believed that an ancient Taal Cone was formed by buildup of large volume dacitic pyroclastic materials more than 140,000 years ago. Several major catastrophic eruptions probably between 27,000 and 5,000 years ago destroyed this greater Taal Cone and ultimately formed the depression now known as Taal Caldera. This depression ...

Rim (craters)
The rim or edge of an impact crater is the part that extends above the height of the local surface, usually in a circular or elliptical pattern. In a more specific sense, the rim may refer to the circular or elliptical edge that represents the uppermost tip of this raised portion. If there is no raised portion, the rim simply refers to the inside edge of the curve where the flat surface meets the curve of the crater bottom. Simple craters Smaller, simple craters retain rim geometries similar to the features of many craters found on the Moon and the planet Mercury (planet), Mercury. Complex craters Large craters are those with a diameter greater than 2.3 km, and are distinguished by central uplifts within the impact zone. These larger (also called “complex”) craters can form rims up to several hundred meters in height. A process to consider when determining the exact height of a crater rim is that Melt (geology), melt may have been pushed over the crest of the initial ...

San Nicolas, Batangas
San Nicolas, officially the Municipality of San Nicolas (), is a municipality in the province of Batangas, Philippines. According to the 2020 census, it has a population of 23,908 people. San Nicolas is derived from Spanish for Saint Nicholas of Tolentino, the town's patron saint. Before 1955, San Nicolas was part of Taal. However, in 1955, with the enactment of Republic Act No. 1229, the municipality, as well as the barrios of San Nicolas - Gipit, Bangin, Pansipit, Calangay, Sinturisan, Talang, Abilo, Balete, Bancora, Saimsim, Maabud, Mulawin, Tambo, Calumala, Alasas, Calawit and Pulang-bato - were created after it split from Taal. The effect entered into force on June 1, 1955. History San Nicolas traces its roots to barrio Wawa, which was once part of the municipality of Taal. The barrio also covered areas of what is now Alitagtag, Agoncillo, Lemery, and San Luis, according to old locals. It was first inhabited by Malays from Borneo. It was the site of Taal's second ...

Tagaytay Ridge
The Tagaytay Ridge, also known as the Tagaytay Range, is a mountain range located at the southern part of the province of Cavite, Philippines, with elevations averaging about above sea level. Stretching west-southwest from Mount Sungay to Mount Batulao in Batangas, the ridge overlooks the picturesque Taal Lake and serves as the northern rim of the expansive Taal Caldera. The wide cavity of the ancient volcano is partially filled by Taal Lake, where Taal Volcano—the country's second most active volcano—is situated near the lake's center. The northern slope of the ridge gradually descends to sea level at Manila Bay Manila Bay (; ) is a natural harbor that serves the Port of Manila (on Luzon), in the Philippines.

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. An eruption that ejects large volumes of magma over a short period of time can cause significant detriment to the structural integrity of such a chamber, greatly diminishing its capacity to support its own roof and any substrate or rock resting above. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given window of 100 years. Only eight caldera-forming collapses are known to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Cone
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of lav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridge
A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements. Classification As in the case of landforms in general, there is a lack of any commonly agreed clas ...

Hydrovolcanic Eruption
A phreatic eruption, also called a phreatic explosion, ultravulcanian eruption or steam-blast eruption, occurs when magma heats ground water or surface water. The extreme temperature of the magma (anywhere from ) causes near-instantaneous evaporation of water to steam, resulting in an explosion of steam, water, ash, rock, and volcanic bombs. At Mount St. Helens in Washington state, hundreds of steam explosions preceded the 1980 Plinian eruption of the volcano. A less intense geothermal event may result in a mud volcano. Phreatic eruptions typically include steam and rock fragments; the inclusion of liquid lava is unusual. The temperature of the fragments can range from cold to incandescent. If molten magma is included, volcanologists classify the event as a phreatomagmatic eruption. These eruptions occasionally create broad, low-relief craters called ''maars''. Phreatic explosions can be accompanied by carbon dioxide or hydrogen sulfide gas-emissions. Carbon dioxide ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano Island (Philippines)
Taal Volcano (; ) is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about south of Manila, the volcano is the second most List of active volcanoes in the Philippines, active volcano in the country with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by Prehistory, prehistoric eruptions between 140,000 and 5,380 Before Present, BP. Taal Volcano has had several violent eruptions in the past, causing deaths on the island and the populated areas surrounding the lake, with an overall death toll of about 6,000. Because of its proximity to populated areas and its eruptive history, the volcano was designated a Decade Volcano, worthy of close study to prevent future natural disasters. The site was declared National Geological Monuments of the Philippines, National Geological Monument in 1998 and a List of national parks of the Philippines, national park ...
