Hawaii's Kilauea volcano could erupt within the next 24 to 48 hours. Scientists believe if the massive eruption takes place, it could send boulders and ash flying through the air as damage could radiate 12-miles from the crater. FEMA is telling residents to monitor hourly radio broadcasts. The volcano has been opening cracks in the earth and spewing lava and toxic gas for more than a week, destroying homes and prompting thousands of evacuations.
