Volcanoes in Japan

Japan is located at the junction of 4 tectonic plates - the Pacific, Philippine, Eurasian and North American plates, and its volcanoes are mainly located on 5 subduction-zone related volcanic arcs where the Pacific Plate descends under the North American Plate along the Kuril Trench and the Japan Trench and underneath the Philippine Sea Plate along the Izu-Bonin Trench. The Philippine Plate itself subducts beneath the Eurasian Plate at the western end, forming the Ryukyu Trench. The principal resulting volcanic ars are:
- Ryukyu Arc and Southwest Honshu Arcs in the south (Philippine plate subducting beneath between the Eurasian Plate),
- Izu-Bonin-Mariana Arc (subduction of Pacific plate beneath Philippine plate)
- Northeast Honshu and Kurile Arc in the north (subduction of Pacific plate beneath the N-American plate)

Photo of this volcano
 The image above is an active volcano in Aira, Japan. The primary volcano type is Caldera. The last known eruption happened this year. It's latitude is 31.592 N, it's longitude is 130.657 E, it's summit is 1117 m, the elevation is 3665 ft, and its volcano number is 282080.





 Volcanic Warning in Japan are issued in relation to expected volcanic disasters, and the names of the affected areas are detailed. Volcanic Forecasts are issued when a volcano starts to become calm. The link https://www.jma.go.jp/en/volcano/ shows the latest Volcanic Warning/Forecast for each volcano and the forecasts that are issued in the last 30 days.

    Hey Manny,
    Such a great post and good job with your research. Just out of curiosity, are any of those volcanoes showing any signs of explosion anytime soon?

    Good that they have a warning/alert system...very wise... I bet most people living there have some kind of app in their phones for warnings...

Plate Boudaries In Japan

Image
  Japan is very unfortunate since they are in the middle of 4 different plate boundaries. They are surrounded by the Phillipine Plate, Eurasion Plate, North American Plate, and the Pacific Plate. Japan is also unfortunate because they are near a convergent boundary. The reason why I say Japan is unfortunate due to all of this because they are located in a spot where there lots of volcanoes located and where many strong earthquakes happen.Japan get very strong earthquakes (compared to what we are used to) because they are near a convergent boundary which are plates that move toward one another. This played a key factor on why Japan was hit by an earthquake of a magnitude of 9 and a tsunami in 2011.

Earthquakes in Japan

Image
  Seismicity is the frequency of earthquakes in an area. According to the Probabilistic Seismic Hazard Maps in Japan, each site will be affected by an earthquake of seismic intensity 6 lower or more within 30 years. It can be seen on the images above that most of Japan's seismicity is located in the East and South. One of the reasons why Japan gets hit by so many strong earthquakes is because they are located on what's called the "Pacific Ring of Fire." This ring of fire is considered the most active earthquake belt in the world and it goes around a couple of plate boundaries. Since Japan is the country to get hit with the most frequent strong earthquakes, they are also the country that is most prepared for earthquakes. Here are some examples on how they prepare for earthquakes: Children in school are taught heavily on how to prepare for an earthquake under any scenario with monthly drills at school After the Kobe earthquake in 1995, building regulations for...
