Aid groups are rushing into Indonesia on the heels of a second earthquake that shook the country yesterday. Indonesia's Health Ministry says nearly 3,000 people may still be trapped under rubble after a powerful earthquake two days ago. Aid organizations are mobilizing a relief effort.
We speak with Bill Horan, the president of Operation Blessing International, about what his organization is seeing on the ground in Indonesia as relief efforts get underway in earnest after this week's earthquakes.
We then talk with Amy Vaughan, a geophysicist from the U.S. Geological Survey. After three earthquakes in three days in Indonesia and the Pacific Islands, followed by tremors in California and Peru, we ask: How interrelated are all these seismological events?
