A Hawaiian volcano has been exploding for five days, destroying 35 homes and other structures as it disgorges rivers of lava and belches out toxic gas. It appeared to have paused on Tuesday, but scientists have warned that it could erupt again.1,700 people have already been forced from their homes on the eastern side of the Big Island. Emergency crews are ready to evacuate more residents if necessary. So far, no deaths or major injuries have been reported.
