A shallow 4.8-magnitude earthquake rattled large parts of Kansas and Oklahoma yesterday, a rare occurrence for two US states more used to tornadoes than tremors.
The quake, which hit at 3:40 pm (2140 GMT), was 5.4 kilometers (3.4 miles) deep and struck close to Conway Springs in Kansas, the US Geological Survey said.
The epicenter was just 53 kilometers from Wichita, the largest city in Kansas, and 200 kilometers from Oklahoma City.
There were no immediate reports of damage or injuries, local media said.
But the quake triggered a torrent of messages on Twitter, with some people saying it shook buildings but others saying they had not even felt it.
