Here's the explosive reason why Hawaii's 'Big Island' is growing

0

Hawaii's 'Big Island' is getting a little bigger thanks to frequent volcanic eruptions.

When lava flows down Hawaii's active volcanoes, such as Kilauea, an active shield volcano, it creeps into the Pacific and forms a new land-like platform.

"These fragments accumulate along the submarine slope to form a loose foundation that will eventually support overlying lava flows that build the delta above sea level," the USGS reports.

Gizmodo reports that all this volatile activity has added hundreds of acres to Hawaii's shorelines.

The lava flow already spans 787 feet.

Visitors are urged to explore the surrounding lava deltas, flat-topped steep-sided volcanic landforms, using extreme caution.
