There are approximately 1500 active volcanoes across the world, and travelers are flocking there every day. There's a lot you can do; from hiking, skiing, or even taking some excellent photographs from a chopper or a small plane.

While there are those that you will visit and come back to your family in one piece, there are other hazardous active volcanoes that guarantee no chance of returning.

As we give you the go-ahead to 15 of the most beautiful active volcanoes you can visit this year, we also give you a red light against these 10 of the deadliest ones you should always stay away from.

25 Stay Away: Galeras – Colombia

Galeras is among the most active volcanoes in Colombia that experiences very frequent eruptions. According to Oregon State University, Galeras volcano has been experiencing these frequent eruptions for over a million years.

It killed six of his colleagues instantly. William was rescued near death after some white-hot projectiles pelted him.

24 Stay Away: Mount Fuji – Japan

A major earthquake took place in Japan in 1707, which, according to Oregon State University, set Mount Fuji off for an eruption later that year. The mountain has not seen another eruption ever since. Following the 9.0- magnitude earthquake that hit Japan in 2011, experts in 2014 warned that Mount Fuji was at risk of another major eruption. The Global Volcanism Program estimates that 25 million people could be affected if Fuji erupted. The explosion that occurred in 1707 sent ash and debris to as far as Tokyo.

23 Stay Away: Krakatoa – Indonesia

Four giant explosions erupted on August 27 in 1883, destroying three-quarters of Indonesia. It was called Archipelago of Krakatoa in those days. The eruptions could be heard from as far as 5000 kilometers away. They produced energy amounting to 13,000 times more potent than the atomic bomb that hit Hiroshima. The tsunamis caused by the eruptions claimed 36,000 lives. Another volcanic activity took place in 1927, creating an Island, Anak Krakatau. The Island increases at a rate of 7 meters per year. Krakatoa has been in an eruptive phase since 1994, which makes it quite dangerous.

22 Stay Away: Mauna Loa – United States

Located in Hawaii, Mauna Loa is the largest active volcano in the world; it takes half the whole Island of Hawaii. Its first documented eruption occurred in 1843, and it has since erupted 33 times. Large volumes of lava flows have reached the ocean since 1984. This is the time a volcanic lava flow came as close to Hilo as 4.5 miles. Hilo is the most populated area on the Hawaiian Island. Mauna Loa is among the five volcanoes on the Island.

21 Stay Away: Mount Agung – Indonesia

Indonesia's Mount Agung is continuously erupting. Last year the mountain showed ash plumes above the volcano continually throughout the year, which started after an eruption that occurred in November 2017. A major eruption occurred in 1963 that lasted almost a year, claiming over 1000 lives, and destroying the property of incredible value. The 1963 occurrence is recorded among the most devastating eruptions the country has ever seen in its history. You should stay away, not just from the volcano, but even from the surroundings.

20 Stay away: Santa Maria – Guatemala

The Santa Maria volcano was inactive for over 500 years, until 1902 when a series of earthquakes set it off to a very violent volcanic eruption. There had been warnings issued directing people to evacuate, but despite that, the eruption went with over 5,000 lives. It created a gap in the south flank of the cone, creating darkness over the Guatemalan skies for several days. The eruption was so potent that its pumice fell on a surface area over 105,000 square miles. Its ash cloud was detected as far California’s San Francisco.

19 Stay Away: Novarupta Volcano – United States

Novarupta Volcano is located in Katmai National Park and Reserve in Alaska. Novarupta was formed as a result of the world's most massive volcanic eruption of the 20th century that occurred in 1912. It sent 30 cubic square kilometers of ash and debris into the air, and its ash flow was so potent that it created the Valley of Ten Thousand Smokes. Sulfurous from the ash cloud caused eye soreness and respiratory problems to the people of Kodiak, and after three days they succumbed to the issues.

18 Stay Away: Colima – Mexico

Colima is among the most active volcanoes in Mexico and North America, which has erupted over 40 times since 1576, with the largest recorded eruption occurring in 1913. Recently, the volcano remained active throughout 2017. And it was very active. This volcano is located 300 miles from Mexico City, in the state of Jalisco. A volcanic eruption would affect the 300,000 people who live within the 25 miles of Colima area, which makes it the most dangerous active volcano in the country.

17 Stay Away: Mount St. Helens – United States

An eruption that occurred on Washington's Mount St. Helens in 1980 is said to be among the deadliest of all eruptions the country has ever seen. It was so destructive that it left about 57 people dead, and a 200 sq. Miles forest destroyed. Thousands of wildlife in that forest was killed. According to research, from the history of Mount St. Helens eruptions, chances of repeat eruptive explosions are too high. If the 1980 event repeats itself, massive amounts of ash fall would severely affect the Pacific Northwest.

16 Stay Away: Taal – Philippines

This volcano has seen 33 eruptions since 1572, with the most recent one being in 1977. It is located 50 kilometers from Philippines' capital, Manila, and occupied by a lake with an island in its interior.
