Thousands flock to Mauna Loa for selfies during dramatic eruption

A highway on the Big Island has become an impromptu viewing point, with thousands of cars jamming it up

The world's largest volcano oozed rivers of glowing lava Wednesday, drawing thousands of awestruck viewers who jammed a Hawaii highway that could soon be covered by the flow.

Mauna Loa awoke from its 38-year slumber Sunday, causing volcanic ash and debris to drift down from the sky. A main highway linking towns on the east and west coasts of the Big Island became an impromptu viewing point, with thousands of cars jamming the highway near Volcanoes National Park.
