These Active Volcanoes Could Burn Through Your Vacation Plans

Volcanoes do what they want to do, and they definitely don't care about your travel plans.

Remember when Iceland's Eyjafjallajökull eruption halted air travel for millions of Europeans for several months in 2010?

Last week, ash clouds from two erupting volcanoes in Indonesia stranded thousands of travelers at airports as they headed home for Eid al-Fitr celebrations.

Nearly 130 volcanoes are currently active in Indonesia, but that's just the tip of the mountain, as far as volcanoes go.

Liz Cottrell, a research geologist and the director of the Smithsonian Institution's National Museum of Natural History Global Volcanism Program, told HuffPost that its database lists 1,540 active volcanoes around the world, about 25 of which are currently erupting at any given time -- and millions more on the seafloor.

"When you go dredge the seafloor along mid-ocean ridge system you find fresh volcanic rocks every time you go," she said.

Below are photos of some of these volcanoes that have erupted around the world.

1. Colima, Mexico

View of the Fire Volcano spewing ash from Queseria community, Colima State, Mexico, on July 11, 2015. Western Mexico's Volcano of Fire spewed a 2.5-mile column of ash and molten rock late Friday, prompting authorities to evacuate 80 people from a small village. The eruptions from the volcano, on the border between the states of Jalisco and Colima, intensified in early July and ash rained down on at least seven communities, according to federal authorities.

2. Mt. Raung, Java

Mount Raung spewed volcanic material into the air as seen from Songgon, East Java, Indonesia, on Thursday, July 16, 2015. Eruptions at two volcanoes Thursday caused closures at three Indonesian airports, including one serving the country's second-largest city.

Ash spewing from the Indonesian volcano closed the airport again on neighbouring Bali on July 12 just a day after it reopened, causing fresh travel chaos for weary holidaymakers stranded on the resort island.

4. Kilauea Volcano, Hawaii

Roughly two thousand six hundred feet span Halemaumau crater, on Kilauea, Hawaii's youngest volcano. Kilauea has been continuously erupting since 1983. In July 2014, residents of Puna, Hawaii were on high alert when lava from the Pu‘u ‘Ō‘ō vent inched toward their homes over the course of the year.

5. Calbuco Volcano, Chile

In April, Volcano Calbuco erupted in Southern Chile for the first time in over 50 years. Thousands were evacuated, and resident Trevor Moffat told Reuters, "It sounded like a big tractor trailer passing by the road, rattling and shaking, guttural rumbling."
