Volcanoes rarely erupt without warning, as molten lava flows, some earthquakes occur, and gray clouds rise before that. Geologists are watching the activity of these volcanoes, which are currently in the explosion phase.

Here we present 12 active volcanoes that may explode soon, according to a writer's report, at night, published by the American magazine "Reader's Digest".

Bagana Volcano

The Bagana Volcano is one of the seven active volcanoes on Bougainville Island in Papua New Guinea. It has erupted 22 times since 1842, usually with a major explosion or lava flow.

This conical volcano has been exploding almost continuously since 1972. As of early December 2018, it began to release gray clouds and gases.

Karangitang volcano

In late December 2018, volcanologists raised the alert level for Karangitang volcano in Indonesia, located along the so-called Ring of Fire around the Pacific Ocean. And this region is witnessing a continuous increase in seismic activity.

Kelawia Volcano

The "Kelawaya" volcano is located in Hawaii, and is among the most active volcanoes on Earth, as its lava flow continues to actively and its crater is currently rising.

This comes after the lava flow activity rose for three months during the summer of 2018, causing its crater to collapse.

Mayon volcano

Mayon volcano erupted twice in the Philippines on the morning of December 27, 2018, causing ash to flow and clouds of steam rising along with the magma runny. Scientists warn of the possibility of a sudden eruption.

This volcano has a "permanent danger zone" with a diameter of 3.7 miles (about 6 km), and an "extended danger zone" with a diameter of 4.3 miles. Therefore, visitors must stay at least five miles away from this active volcano.

Sitkin Volcano

According to an American geological survey, Greater Sitkin Island - which is among the Aleutian Islands in Alaska - has been experiencing volcanic unrest since September 3, 2018. Although the daily updates of last January did not record little or no activity With no activity, she remained under observation due to the small earthquakes that were active under her last August, which eventually led to a small volcanic eruption.

Mount Agung Volcano

It is a highly explosive volcano in Bali, Indonesia, and it has been erupting continuously for the past two years. According to the newspaper "Jakarta Post", this volcano witnessed the last time a short eruption on the evening of January 21 last, with a duration of one minute and 12 seconds. Ash was also emitted.

Mount Cleveland Volcano

The map of Alaska Peninsula and the Aleutian Islands shows a whole series of active volcanoes, including Mount Cleveland Volcano. According to its observatory, this mountain has "very high surface temperatures" at the top, and periodic explosions occur without warning.

Mount Etna volcano

This stratum volcano, with a height of about 3048 meters and located on Sicily, is one of the most active volcanoes in the world. In late January, he was showing signs of his activity.

Mount Vinyamenov volcano

The "Vinyaminov" volcano was erupting from time to time and sending out emissions of ash that are not important, but in December 2018 its lava and its ashes caused some potential safety hazards to an aircraft.

Nevado del Ruiz volcano

This stratum volcano, about 5181 meters long and located in Colombia, has not exploded for 20 years. However, in recent years, it has rebounded once again with seismic tremors and steam and ash.

Oldwinio Linghai Volcano

It is known as the "Mountain of Gods" in the Tanzanian Masai tribes. This volcano developed a crater at its summit after its last eruption in 2007. Since then, the volcano slowly began to lava into that crater, which puts it in a state of activity.

Sinjiang Mountain Volcano

This active volcano is located in Indonesia. In 2017, the volcano witnessed an explosion called "Stromboli eruption." Since then, the mountain has become very rough and has emitted ash emissions.
