10 Numbers To Know About Hawaii’s Most Dangerous Volcano

Get fast facts about one of the most active volcanoes in the world, and learn more about how you can help people grappling with its growing threat in Hawaii.


Dangerous, volcanic activity near Hawaii’s Kilauea volcano continues to intensify, and its largest eruption yet happened around 4:17 a.m. on Thursday, May 17. The eruption spewed a mix of ash and toxic gas six miles into the air.

The Kilauea volcano is located on the southern end of the Island of Hawaii, the largest of the eight Hawaiian Islands. Kilauea is one of the youngest volcanoes in the area, yet is believed to be the most active on earth.

Although volcanic activity is nothing new for Kilauea, signs of bigger trouble emerged in mid-March, when increased magma in the system prompted one of the volcano’s vents to inflate and ultimately caused its crater floor to collapse, according to LiveScience.

Here are 10 figures that will help you learn more about one of the most active volcanoes in the world, and its recent ominous activity:
