Origin of the name

Regarding the origin of the name, according to "Shinsen Rikuokukunishi", there are eight (many) instep-shaped peaks and many Tashiro (wetlands) on the mountain.

Nakamichi, etc.In "Towadamura History"Masumi Sugae"Towada no Umi" and "Ihate no Yama"1407(Oei 14 years) "Three Kingdoms BiographyIntroducing the theory that Towada's old name "Koda-dake" originated from "Nuka-dake" in "Nuka-dake", and I am impressed with Masumi Sugae's knowledge. In "Sangokudenki", one day, a woman said to the difficult store, "There is a pond in the west three villages of the ridge of these words, and there is a pond at the ridge of Nuka. There is an eight-headed Orochi in the pond. With my wife, I lived in the pond in the beginning of January on the 1th of January, and in this pond on the 15th of the end of January, so now. Is just about to come. Please keep in mind. "This is the first appearance of Nansobo and Hachirotaro (Miho Legend).It is said that this Nuka was the origin of Nukanobu-gun, the ancient name of the county in the eastern part of Hakkoda Mountains, and was later read aloud and changed to Koda-dake.Before this,GenrokuThis theory is also mentioned in "Azuma Mukashi Monogatari," which is said to have been written by a doctor in Kyoto who stayed in the Southern Clan. It is possible that Masumi Sugae read this book while traveling around the Southern Clan.

The first person to record the characters of the bran1731(Kyoho 16 years) "Isshi TsugaruIn1536In "Tsugaru-gun Chumeiji" (5th year of Astronomy), "The border between Tsugaru and Nukanobu, Lake Nukanobu, Chijin Godai, and the sect of Toga's Reikendo for several years. He expelled Hachiryu, a priest named Nanzobo, and entered the swamp of Towan. Until the fifth year of Tenbun, he was over 2 years old. "Since then, Hakkoda has been broadly divided into two categories: Koda and Hatsukouda (Yatsukoda).1645In the pictorial map of (Shoho 2nd year), Hakkoda is named "Kautatake" by the Tsugaru clan and "Takadatake" by the southern clan, both of which show that the official name was Koda.[7].

Mountains that make up the mountain system TheNational Route 103-National Route 394It is divided into the northern Hakkoda mountain range and the southern Hakkoda mountain range with the overlapping roads of the above, and the latter is older.

Although it is a mountainous area of ​​less than 1600m, which is not so high nationwide, it divides Aomori Prefecture into east and west, and has a great influence on the characteristics of each climate.In the summer, the cold and moist northeastern monsoon from the Pacific OceanStop, And the Pacific side of Aomori Prefecture is hit by heavy fog and cold damage.On the other hand, the west side of Mt. Hakkoda is an excellent rice-growing area, and the remains of paddy fields from the Yayoi period have been discovered.In winter, the moist northwest monsoon blows from the Sea of ​​Japan, bringing snow to the Tsugaru region.On the other hand, the eastern side of Mt. Hakkoda has a high rate of fine weather and little snowfall.By Hakkoda Mountains in both summer and winterFern phenomenonIs believed to be.

Takada Odake is famous as the toughest mountain trail in the Hakkoda mountain range, with the mountain trails connecting to the top almost in a straight line.

Topography and eruption history

Hakkoda Mountain is located to the southLake TowadaAs well ascalderaIt is a volcanic group with.There is a large moorTashiroheiThe depression in the vicinity corresponds to the northern half of the caldera, and the southern half is filled with volcanic groups such as Hakkoda Odake, which erupted after the formation of the caldera.Minami Hakkoda, where Kushigamine (1,517m) is located, corresponds to the old former caldera volcano.The giant eruptions that formed the caldera have occurred twice in the past (2 years ago and 65 years ago) just by being investigated.Minami Hakkoda has completed volcanic activity before the second caldera eruption.Kita-Hakkoda started its activity 40 years ago to fill the southern half of the caldera, and many (not very large) erupted repeatedly.StratovolcanoWas formed.In recorded history溶岩There is no big eruption that flows out, but from some parts of the mountainsVolcanic gasIs fumarolic.

Observation system

Japan Meteorological AgencyDisaster Prevention Research InstituteEarthquakes are being observed by earthquake observation facilities such as [9].

Tohoku-Pacific Ocean EarthquakeSince (March 2011, 3), the number of earthquakes with epicenters around Mt. Hakkoda has increased.Also,2013Since February, there have been sporadic earthquakes with epicenters just below the summit.[9]..On the other hand, GPS observation shows that the mountain body is expanding.[10]It was reported that the Japan Meteorological Agency installed new observation equipment on June 2013, 6 and strengthened monitoring.[11].. Since July 2013, broadband seismic observations have been carried out by the Tohoku University Eruption Prediction Research and Observation Center and others.[12]..In September 2013, temporary gravity observations were carried out at 9 observation points by the Earthquake Research Institute, the University of Tokyo and the Eruption Prediction Research and Observation Center of Tohoku University.[13].

From December 2016, 12, the Japan Meteorological Agency will be added to the constantly observed volcanoes that monitor volcanic activity 1 hours a day.[6].

Fatal accident due to volcanic activity

1997Three SDF personnel during training spouted from a depression and stayed there at a high concentration.carbon dioxideHas caused an accident of suffocation.In June 2010, it is probable that one female junior high school student who was visiting to pick edible wild plants was staying at the site in a swamp off the mountain trail above Sukayu Onsen.Volcanic gasHas caused an accident of poisoning death.
