Mount Hakone
, with its highest peak Mount Kami (1,438 meters), is a complex volcano in Kanagawa Prefecture, Japan that is truncated by two overlapping calderas, the largest of which is 10 × 11 km wide. The calderas were formed as a result of two major explosive eruptions about 180,000 and 49,000–60,000 years ago. Lake Ashi () lies between the southwestern caldera wall and a half dozen post-caldera lava domes that arose along a southwest–northeastern trend cutting through the center of the calderas. Dome growth occurred progressively to the south, and the largest and youngest of them, Mount Kami, forms the high point of Hakone. The calderas are breached to the east by the Haya River canyon. Mount Ashigara is a parasitic cone. The latest magmatic eruptive activity at Hakone occurred 2,900 years ago. It produced a pyroclastic flow and a lava dome in the explosion crater, although phreatic eruptions took place as recently as the 12–13th centuries AD. According to the n ...

Phreatic 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 dioxid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Izu–Bonin–Mariana Arc
The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia. The IBM arc system extends over 2800 km south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sealevel. The IBM arc system lies along the eastern margin of the Philippine Sea Plate in the Western Pacific Ocean. It is the site of the deepest gash in Earth's solid surface, the Challenger Deep in the Mariana Trench. The IBM arc system formed as a result of subduction of the western Pacific plate. The IBM arc system now subducts mid- Jurassic to Early Cretaceous lithosphere, with younger lithosphere in the north and older lithosphere in the south, including the oldest (~170 million years old, or Ma) oceanic crust. Subduction rates vary from ~2 cm (1 inch) per year in the south to 6 cm (~2.5 inches) in the north. The volcanic islands that comprise these island ar ...

Calderas Of Honshū
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. 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 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 each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish ', and Latin ', meaning "coo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Mount Hakone
The geological History of Mount Hakone, has been researched by Dr. Hisashi Kuno et al., with Mount Hakone, located in Hakone, Kanagawa, Japan, as a volcano from the Quaternary period. Mount Hakone started about 500,000 years ago with the eruptions, that created Mount Kintoki and Mount Myōjō on the current "Old outer rim"; and the subsequent eruptions about 160,000 years ago made the "New outer rim", on which are and Mount Takanosu (Kanagawa). From 50,000 years ago, new eruptions further created in the "Central volcanic cones" Mount Kami (), the highest peak in Hakone, Mount Koma and other peaks; and about 300,000 years ago, the lava domes such as Mount Futago emerged. Later about 3,000 years ago, the phreatic eruption on the northwest side of Mount Kami caused landslides, creating the Owakudani and, in the huge caldera, the Sengokuhara and Lake Ashi.

Mount Futago (Hakone)
Mount Futago ( = ''Futago-Yama'') is a twin-peak mountain in the central volcanic cones of Mount Hakone, located in Hakone, Kanagawa, Japan. It consists of Upper Futago Mountain (1,099 meters) in the north, and Lower Futago Mountain (1,065 meters) in the south. Although entering this mountain is prohibited in order to preserve nature, Mount Futago is easily recognizable from various directions because of its prominent twin peaks and the relay towers of NTT Telecommunications East and NTT Docomo, which play an important role in Japan's busy east-west telecommunications.

Mount Kanmuri (Kanagawa)
Mount Kanmuri ( = ''Kanmuri-ga-Take'', meaning the "mountain with a Kanmuri hat") is one of the peaks of Mount Hakone, in Hakone, Kanagawa, Japan, with an elevation of 1,409m meters. When the phreatic eruptions occurred on the northwestern slope of Mount Kami about 2,900 years ago, the underground magma created a lava dome, which is the current Mount Kanmuri. These eruptions caused the damming of the Haya River, creating the Sengokuhara and Lake Ashi. This mountain looks like the " Kanmuri" headwear, which used to be worn by the noble men in ancient Japan. Climbing Mount Kanmuri Climbing mountains is a popular sport in the Mount Hakone area. To the top of Mount Kanmuri, there are three trails: from Mount Koma Summit Station of the Hakone Komagatake Ropeway, from Sōunzan Station of Hakone Tozan Cable Car, and from Ōwakudani Station of the Hakone Ropeway. The trail from Ōwakudani gets closed when too much volcanic vapor is evident. . See also *Fuji-Hakone-Izu National P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
