Clouds of dust belched from the corners of almost every room in Joe Reneau's house as the biggest earthquake in Oklahoma history rocked the two-story building.
A roar that sounded like a jumbo jet filled the air, and Reneau's red-brick chimney collapsed and fell into the roof above the living room. By the time the shaking stopped, a pantry worth of food had been strewn across the kitchen and shards of glass and pottery covered the floor.
"It was like WHAM!" said Reneau, 75, gesturing with swipes of his arms. "I thought in my mind the house would stand, but then again, maybe not."
The magnitude 5.6 earthquake and its aftershocks still had residents rattled Sunday. No injuries were reported, and aside from a buckled highway and the collapse of a tower on the St. Gregory's University administration building, neither was any major damage. But the weekend earthquakes were among the strongest yet in a state that has seen a dramatic, unexplained increase in seismic activity.
Oklahoma typically had about 50 earthquakes a year until 2009. Then the number spiked, and 1,047 quakes shook the state last year, prompting researchers to install seismographs in the area. Still, most of the earthquakes have been small.
