"Ballistic blocks" shot from Hawaii volcano

Posted: Updated:

HAWAII - "Ballistic blocks" the size of microwave ovens shot from Hawaii's Kilauea volcano on Wednesday in what may be the start of explosive eruptions that could spew huge ash plumes and hurl smaller rocks for miles, the U.S. Geological Survey said.

Such eruptions, last seen nearly a century ago, have been a looming threat since Kilauea, one of the world's most active volcanoes, erupted nearly two weeks ago.

Explosions in Kilauea's crater sparked an aviation red alert due to risks the ash plume could blow into aircraft routes and damage jet engines.

More explosions are expected and may be more powerful, the USGS warned. These steam-driven blasts could send a 20,000-foot ash plume out of the crater, hurling 10-12 ton boulders up to half a mile and scatter pebble-sized rocks over 12 miles, the USGS has said.

This type of eruption has the potential to carpet the Big Island in much thicker ash than current dustings and possibly spread the powder and volcanic smog across the Hawaiian islands and farther afield if it enters the stratosphere.

A 4.2 magnitude earthquake at the volcano at 8.36 a.m. prompted authorities to issue an alert reassuring rattled Big Island residents that there was no risk of a tsunami from the volcanic activity.

Ash is a new hazard for Hawaii's Big Island, already grappling with volcanic gas and lava that has destroyed 37 homes and other structures and forced the evacuation of about 2,000 residents from a small area in the southeast Puna district.

Lava has burst from 21 giant ground cracks or fissures and torn through housing developments and farmland, threatening two highways that are exit routes for coastal areas.
