"Thunderquake" actually a "Super Bolt"

It woke up sleepy Tulsans, set-off car alarms and freaked out the family pet. Many people thought it was an earthquake that hit Tulsa at 3:33 this morning.

Instead, says National Weather Service Meteorologist Steve Amburn, is was a "Super Bolt." Amburn says a super bolt is a positively-charged cloud-to-ground stroke of lightning.

Computer records indicate a single "super bolt" struck in the heart of South Tulsa just after 3:30.

No damage from the super bolt is reported.
