Vibrations From Indonesian Quake Felt In Oklahoma
Geological Survey Records Shockwaves From Massive Quake

OKLAHOMA CITY -- Jolts from the enormous earthquake in Indonesia that killed thousands were felt in Oklahoma.

The Oklahoma Geological Survey in rural Tulsa County recorded shock waves from the 9.0-magnitude quake beginning at 7:13 p.m. Saturday, 15 minutes after the temblor occurred beneath the Indian Ocean.

The largest waves, with a .12-inch vertical movement in Oklahoma, were logged at 7:36 p.m., local time.

"This is the type of earthquake that's recorded by every seismograph in the world, and recorded very clearly," said Jim Lawson, chief geophysicist with the OGS. "This is almost the biggest earthquake that could occur."

The large waves felt in Oklahoma may have caused water in Oklahoma ponds and lakes to slosh back and forth slowly, a motion called a seiche, Lawson said. It also may have caused some tall buildings in the state to sway slightly, he said.
