Good wednesday morning. It has been a sleepless night for many as aftershocks continue to rock chile. A powerful earthquake there last night triggered a small tsunami forcing people into the streets and causing widespread panic. The 8. 2 magnitude quake struck off the countrys northern coastline. Authorities posted tsunami warnings for several south american countries but have since canceled them. Right now the death toll is now at least six people. Two other people died from heart attacks. Others were crushed to death as people fled buildings. More than two dozen strong aftershocks followed the initial quake. [ sirens ] the quake forced evacuations along chiles entire pacific coast, but people were urged to stay out of their cars and head for Higher Ground on foot to keep the roads clear. Everyone is to stay up on the mountains. Most of the damage has been limited to houses made of adobe, and while some injuries have been serious, most have been minor. Some 300 inmates escaped from a womens prison in one city, and chiles military dispatched special forces to guard against looting. The shock waves were felt hundreds of miles away shaking buildings as far away as bolivia and peru. You could feel the wall moving, as well as the floor, and theres a tent and a veranda back in the garden, and you could really see that moving back and forth. Reporter the earthquake even triggered microscopic seismic measurements in new yorks central park. There have already been more than two dozen aftershocks some measuring as much as 5. 1.

S. , west coast or alaska. However, a tsunami advisory has been issued for hawaii, but its largely a precaution. No flooding is expected there. Initial waves are expected to hit there this morning just before 9 30 eastern time. Thats the middle of the night in hawaii.

Reporter General MotorsCeo Mary Barra is beginning day two of questioning by lawmakers on capitol hill later this morning after being grilled in the spotlight for more than three hours on tuesday.

Gms failure to act went on and on until just two months ago when it finally started to recall these vehicles. Reporter since barra took over gm in january, the automaker has recalled nearly 2. 6 million vehicles because their ignition switches could turn off unexpectedly shutting down the car, disabling the power steering, air bags and brakes. Lawmakers pressed barra on why the company decided for nearly a decade that fixing the ignition was too expensive. Documents provided by gm show that this unacceptable cost increase was only 57 cents. We apologize for what has happened, and we are doing a full investigation.
