The Most Visited Dangerous Active Volcanoes In Japan

Dangerous
calendarJun 10 2017
Japan’s Mt. Fuji is an active volcano about 100 kilometers southwest of Tokyo.
Mount Fuji iss highest and most iconic landmark in Japan.
Mount Fuji has erupted at least 16 times since 781 AD and the eruptions are typically violent.
A popular place for viewing Mt. Fuji is Tenjo-Yama Park where a cable car takes visitors 1,000 meter up to the viewing platform.
Approximately 35 million people live in the potential fall out zone of a major eruption.
The last eruption of Fuji in 1707-1708 was preceded by a large earthquake in Osaka.
The eruption was explosive, sudden and sustained.
It resulted in a great loss of life.
Volcanic ash fell as far away as Edo (present day Tokyo).

Mount Asama

Mount
calendarJun 10 2017
Asama, Honshu's most active volcano, overlooks the resort town of Karuizawa, 140 km NW of Tokyo.
The volcano is located at the junction of the Izu-Marianas and NE Japan volcanic arcs.
Asama is Honshu's most active volcano, and has an historical record dating back more than 1300 years.
Eruptions have sent lava and rock flying hundreds of kilometers and started many fires.
There have also been thousands of earthquakes at the site. There's a risk of a catastrophic eruption at Mount Asama.

Mount Aso

calendarJun 10 2017
Mount Aso is one of the world's largest volcanoes — its caldera is 120 kilometers in circumference.
An eruption 90,800 years ago released 600 km³ of lava and debris.
An eruption that size today would have devastating consequences that would extend far beyond Japan's borders.
It consists of five separate volcanic peaks, one of which is still active and regularly emits volcanic smoke.

Mount Shinmoedake

calendarJun 10 2017
Mount Shinmoedake, part of the Kirishima range, has dramatically erupted on the island of Kyushu in southern Japan, after a gap of 52 years.
The eruption started on January 26, 2011 at 7:30 AM and it is said to be the strongest eruption since 1959, spewing smoke up to 2.5 km in the air and throwing rocks up to 1.5 km.
Giant ash clouds pouring out of the volcano prompted the Tokyo VAAC to issue an ash warning for places above 25,000 feet (7.6 kilometers) and as a result of the eruption, an area of 2 km around the volcano has been evacuated.

Sakurajima

Sakurajima
calendarJun 10 2017
Sakurajima is an active composite volcano and a former island in Kagoshima Prefecture in Kyushu, Japan.
The lava flows of the 1914 eruption caused the former island to be connected with the Osumi Peninsula.
A popular place for viewing Sakurajima volcano is Yunohira Lookout which is a two hour hike or 15 minutes drive from Sakurajima harbor.

Mount Unzen

Mount
calendarJun 10 2017
Unzen is a large complex volcano made of several adjacent and overlapping lava domes.
The volcano covers much of the Shimabara Peninsula and is east of the city of Nagasaki.
In 1792, collapse of the Mayu-yama lava dome created an avalanche and tsunami that killed an estimated 14,524 people.
Most of the people were killed by the tsunami.
Unzen volcano is a terminology used to refer to what is effectively a complex of several volcanic dome structures with a total volume of about 35 cubic km.
The volcanoes development can be traced back to about 500,000 years ago with four main dome structures having arisen in the last 150,000 years; Nodake, Myokendake, Fugendake (i.e. Mt Fugen) and Mayuyama.
