A tourist attraction of an active volcano

Volcanic geology can always form a magnificent and peculiar landscape and become a tourist attraction. Sometimes we revel in it, but forget that there are active volcanoes that will erupt at any time.

In Yellowstone National Park

Ornamental: ★★★★★★★

Danger: ★★★★★★★

Yellowstone National Park is the most primitive and oldest national park in the world. The remarkable feature that initially aroused people's interest and made Huangshi a national park was the geothermal phenomenon in geology. There are more geysers and hot springs, colorful yellowstone river Grand Canyon, fossil forests and Yellowstone Lake here than anywhere else in the world.

However, for many years, visitors to Yellowstone National Park did not realize that they were seeing the largest active volcano in the world. All these hot springs, geysers and steam caves need huge core lava energy to maintain, and the heat emitted by the lava in Yellowstone National Park is very close to the surface. Experts say that the eruption period of Yellowstone volcano is 600,000-800,000 years, which is 642,000 years since the last eruption. The world's largest super active volcano has entered a red warning state, even if it is not affected by external forces (referring to solar activity and artificial drilling). It could break out at any time.

Once it erupts, the United States will be hit hard, and two-thirds of the country will be submerged by volcanic ash, with the destructive power of 1980 times that of the San hellens volcano that erupted in 2000. By then, the volcanic eruption will also release toxic gases into the air, thousands of flights will be grounded and millions of people will be displaced.

Mount fuji, Japan

Ornamental: ★★★★★★★

Danger: ★★★★★☆.

Mount Fuji is known as the "Holy Mountain" by the Japanese people and is a symbol of the Japanese nation. The whole mountain is tapered. At first glance it looks like an upside-down fan. Japanese poets once praised the poem "Jade fan hanging upside down in the East China Sea" and "Fuji Snow Reflects Sunrise".

Mount Fuji is actually a dormant volcano. It is said that it was formed by an earthquake in 286 BC. Since it was recorded in writing in 78 1 year, * * has erupted 18 times, and the last time was 1707 times, thus becoming a dormant volcano. The eruption of 1707 was caused by an earthquake of magnitude 8.4.

Bali Island

Appreciation: ★★★★★☆.

Danger: ★★★★★☆.

An active volcano in Bali, Indonesia, also known as Bali Peak. At an altitude of 3140m, it is the highest mountain on the island and is regarded as a sacred mountain by local people. Volcano is located in the northeast of the island, and the eruption cycle is generally about 50 years. An eruption in 1963 was the most violent in more than a hundred years. The heat wave is as high as 10000 meters, and volcanic ash fills the island at an altitude of 4000 meters, causing heavy casualties to people and animals.

Luzon, Philippines

Appreciation: ★★★★☆☆☆

Danger: ★★★★★☆.

Mayon volcano in the south of Luzon Island is located in Legaspi. Mount Fuji in Japan is called the most perfect volcanic cone in the world, second only to it, and people often compare it with Mount Fuji in Japan. It is a famous tourist attraction in the Philippines. Recently, it has been on the verge of eruption many times. Although the Philippine government evacuated nearby residents, it still attracted many volcano enthusiasts and photographers, who hoped to see the perfect volcanic eruption scene. 16 16 has recorded more than 30 outbreaks so far, and 1993 killed 75 people. The most destructive one happened in 18 14, when the city of Kagshawa was buried.

Changbaishan Tianchi

Appreciation: ★★★★★☆.

Danger: ★★★☆☆☆

Changbai Mountain used to be a volcano. According to historical records, it has erupted three times since16th century. When a volcano erupts and spews a lot of lava, the crater forms a basin. After a long time, the accumulated water became a lake and became Tianchi.

Yangmingshan National Park in Taiwan Province Province

Appreciation: ★★★★★☆.

Danger: ★★★☆☆☆

Datun Mountain Group is a part of Yangmingshan National Park, including Datun Main Peak, Nanfeng Peak, Xifeng Peak, Miantianshan Mountain, Xiangtianshan Mountain, Zhongzheng Mountain, Erzi Mountain, Caigongkeng Mountain, Zhentou Mountain and Oven Mountain. Due to the superior natural environment, unique and beautiful scenery has been formed here.

In 2009, researchers from Academia Sinica in Taiwan Province Province analyzed the surface structure of Datun Volcano Group, overturned the statement that Datun Volcano Group was a "dormant volcano", revised the latest eruption time from 200,000 years ago to 5,000 years ago, and pointed out that if Datun Volcano Group erupts, the disaster may be worse than the "92 1 earthquake".
