A magnitude 5.1 earthquake rocked Southern California over the weekend. It struck along a fault that's less well-known than the San Andreas, but one that's potentially even more dangerous. Jason Carroll takes a closer look.
Satellites are playing a key role in the search for Flight 370. But so far, they have not been able to spot any debris from the missing plane. Weeks into the search, there are questions about why satellites have not been able to provide more accurate information. Gary Tuchman got an up close look at how they work.
Planes and ships are combing the Indian Ocean for any sign of the missing plane. The hope is they can zero in on the location while the black boxes are still pinging their locations. Navy Commander William Marks is looking for Flight 370 on the USS Blue Ridge. He tells Anderson they are spotting debris everyday, but so far "nothing associated with the aircraft."
For weeks, Malaysian authorities reported the final words from Flight 370's co-pilot to air traffic controllers was "All right, goodnight." That is a non-standard sign-off, and it raised serious questions about what may have been happening inside the cockpit.

Anderson gets the latest developments from Kyung Lah in Australia and Nic Robertson in Kuala Lumpur.
