Akita-Yake-Yama is a small stratovolcano in Akita Prefecture, Japan, that is known for its radioactive waters. A small parasitic lava dome is located four kilometers from the volcano. [1]
Eruptions during historical times are limited to moderate phreatic eruptions, which have been recorded since 1678. [1]
On 11 May 1997, after a landslide a few days later, an eruption began. The eruption took place at a hot spring in a resort called Sumikawa-Onsen. On 10 May, tremors were reported at the hot spring up until midnight. On 11 May, a party saw a fast moving landslide moving down the slope of the volcano 20 minutes before the explosion. The eruption started around 08:00 am and was witnessed by a pilot who was flying over the area. He reported that he saw a water and steam ejection, like a giant geyser, followed by an eruption of black smoke. The explosion triggered a mudflow, that travelled down a nearby river valley. The field party then noticed tephra deposits in the mudflow, concluding that they were from the eruption site. The mudlow destroyed two hotels at the foot of the volcano, there were no fatalities.
On 16 August 1997, a tourist reported that a small eruption had taken place at the Karanuma crater (a crater near the summit). It occurred after a few days of volcanic tremors. The eruption formed a 20 m diameter crater on the SE rim of the Karanuma crater. The eruption lasted for 70 minutes.
Mount Suribachi is a 169-metre (554 ft)-high mountain on the southwest end of Iwo Jima in the northwest Pacific Ocean under the administration of Ogasawara Subprefecture, Tokyo Metropolis, Japan.
On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am. The eruption, which had a Volcanic Explosivity Index of 5, was the first to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. It has often been declared the most disastrous volcanic eruption in U.S. history.
Mount Asama is an active complex volcano in central Honshū, the main island of Japan. The volcano is the most active on Honshū. The Japan Meteorological Agency classifies Mount Asama as rank A. It stands 2,568 metres (8,425 ft) above sea level on the border of Gunma and Nagano prefectures. It is included in 100 Famous Japanese Mountains.
Sakurajima is an active stratovolcano, formerly an island and now a peninsula, in Kagoshima Prefecture in Kyushu, Japan. The lava flows of the 1914 eruption connected it with the Ōsumi Peninsula. It is the most active volcano in Japan.
The 2004–2008 volcanic activity of Mount St. Helens in Washington, United States has been documented as a continuous eruption in the form of gradual extrusion of magma. Starting in October 2004 and ceasing in January 2008, a new lava dome was built up. The new dome did not rise above the rim of the crater created by the 1980 eruption of Mount St. Helens.
Mount Rinjani is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara. It rises to 3,726 metres (12,224 ft), making it the second highest volcano in Indonesia. It is also the highest point in the Indonesian province of West Nusa Tenggara.
Kuchinoerabu-jima, is one of the Satsunan Islands, usually classed with the Ōsumi Islands belonging to Kagoshima Prefecture, Japan. The island, 38.04 km2 (14.69 sq mi) in area, has a population of 147. The island can only be reached by boat as it has no airport. There is regular ferry service with Yakushima, which is about 15 km to the east. Travel time is approximately 1 hour. The islanders are dependent mainly on fishing, agriculture and seasonal tourism. The entire island is within the borders of the Kirishima-Yaku National Park.
Mount Chōkai is an active volcano located on the southern border of Akita and Yamagata in the Tōhoku region of Japan, and is 2,236 m (7,336 ft) tall. Because of its (roughly) symmetrical shape and massive size, it is also variously known as Dewa Fuji (出羽富士), Akita Fuji (秋田富士) or Shōnai Fuji (庄内富士) depending on the location of the viewer. In addition to being one of the 100 Famous Landscapes of Japan, it is also included as one of the 100 famous mountains in Japan, and famous 100 Geographical Features of Japan. It is surrounded by Chōkai Quasi-National Park. It is also a National Historic Site of Japan, and is regarded as a sacred mountain by followers of the Shugendō branch of Shinto which has the shrine Chōkaisan Ōmonoimi Shrine there and is popular with hikers.
Mount Kusatsu-Shirane is a 2,165 m (7,103 ft) active stratovolcano in Kusatsu, Gunma, Japan. It is called Kusatsu Shirane to differentiate it from the Mount Nikkō-Shirane on the other side of Gunma Prefecture. The summit of Kusatsu-Shirane volcano, located immediately north of Asama volcano, consists of a series of overlapping pyroclastic cones and three crater lakes. The largest of these is Yu-gama, an acidic emerald green lake with rafts of yellow sulfur sometimes seen floating on its surface.
Prediction of volcanic activity, or volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
Volcán San Cristóbal is the highest volcano in Nicaragua at 1,745 m (5,725 ft). Near the northwest corner of the country, close to the border with Honduras, it forms a backdrop to the city of Chichigalpa, Chinandega. It is also among the most active volcanoes in Nicaragua.
Mount Adatara is a stratovolcano in Fukushima Prefecture, Japan.
The 1888 eruption of Mount Bandai was a major volcanic eruption which occurred during the Meiji period of the Empire of Japan. The eruption occurred on July 15, 1888, pyroclastic flows buried villages on the northern foot of the mountain, and devastated the eastern part of Bandai region, Iwashiro Province north of Tokyo. At least 477 people were killed, and hundreds more were injured and rendered homeless.
Mount Eniwa is an active volcano located in Shikotsu-Toya National Park in Hokkaidō, Japan. It sits opposite Mount Tarumae and Mount Fuppushi on the shores of Lake Shikotsu, the caldera lake that spawned the volcanoes. Mount Eniwa is the tallest of the three volcanoes.
