Nearly 31 houses and commercial buildings have been destroyed by the massive lava pouring out of the Kilauea volcano on Hawaii’s Big Island. The volcanic eruption began last month and experts have said that the lava at one time was spilling out over 200 feet into the air. US Geological Survey volcanologist Wendy Stovall has reported that new fissures continue to emerge throughout the Kilauea. Over 1,700 people have been evacuated from the area. There are hundreds of thousands of volcanos that can erupt at any time. These are five volcanoes that could erupt next.

1. Ol Doinyo Lengai, Tanzania

Geologists are beginning to see signs of an imminent eruption at the Tanzanian volcano Ol Doinyo Lengai. The volcano has become known as the “Mountain of God.” Two years ago scientists placed five sensors around the peak and eight months later, the geologists saw a spike in their data. Scientists report that the spikes not only means there are rumblings but parts of it are moving forward, meaning an eruption could be coming very soon. This volcano could be fatal for local villages in the area and could end up destroying one of the world’s oldest historic site known as “the dancehall” which is known for its collection of 400 human footprints dating back 19,000 years.

2. Mount Agung, Bali

Last fall, officials sent out warnings about the possibility of an eruption of Mount Agung on the island of Bali. Scientists recorded tremors and a spike in volcanic activity. Indonesia’s Centre for Volcanology of Geological Hazard Mitigation said that all signs show that the potential of an eruption is very high.

The volcano erupted last November and forced the cancelations of flights into and out of Bali canceled. The last serious eruption was in 1963 and resulted in the death of over 2,000 people.

3. Hekla, Iceland

Iceland is one of the most volcanic countries on earth. Iceland faces major volcanic eruptions every three to seven years.

The latest eruption was in 2010 when air Travel was halted for six days because of a massive cloud of volcanic ash. The halt in air travel cost the European economy four billion in euros. Since 1970, the volcano has erupted once every ten years. However, it has now laid dormant since 2000. The University of Iceland and Professor Einarsson have warned the media that the public needs to stay away from the volcano.

4. Katla, Iceland

North from the Hekla volcano is the Katla volcano. Katla last erupted 99 years ago in 1918. Eight of the last ten eruptions took place between September and November. The glacial ice is what is worrying the locals regarding a potential eruption. If an explosion occurred, the ice covering the volcano would melt and flood the nearby areas so much that local authorities have plans to evacuate the country’s entire southern coast.

5. Oraefajokull, Iceland

Experts are warning that the Oraefajokull volcano is ready to erupt. A half-mile caldera has grown and scientists have seen a massive spike in seismic activity in surrounding area, meaning Oraefajokull could be getting ready to erupt. Iceland’s meteorological office has said they are unsure how the situation will evolve. Oraefajokull is located in the Vatnajokull National Park on the southeast part of the country. The last eruption was in 1727 and it is also covered in ice. Oraefajokull has become Iceland’s largest volcano.
