Awakened by an EARTHQUAKE this morning

At 4:36 we awoke to the windows rattling and the entire house shaking. I kid you not, we thought a tornado was hitting the house, until both kids yelled from upstairs! As we headed up we note that there is not any wind to speak of. We just had an earthquake! A small picture fell off Caitlyn's wall and several books off the bookshelf in her room. The pictures on the walls in the loft are all askew. It doesn't look in this moment like anything else moved, except our house vibrating for about 15 seconds! (The news is calling it officially 20 seconds) Paige felt a light wave of shaking that woke her and then everything shook and the windows rattled, effectively waking the rest of the house for the Rattle! It felt like a two wave quake, a small forequake and then the larger quake wave.

Interesting fact: It is the anniversary of the 1906 San Francisco Quake. It hit April 18, 1906 at 5:12am.

This is the quake that woke up the Clausens today! Earthquake felt in St. Peters, Missouri.

(CNN) -- A magnitude 5.4 earthquake, centered 127 miles east of St. Louis, Missouri, shook southern Illinois at 4:36 a.m. (5:36 a.m. ET) Friday, according to the U.S. Geological Survey.

There were no immediate reports of damage, according to USGS spokeswoman Jessica Sigala.

People as far north as Chicago and as far west as St. Louis reported feeling the quake, Sigala said.

The quake is believed to have involved the Wabash fault, a northern extension of the New Madrid fault about 6 miles north of Mt. Carmel, Ill., said United States Geological Survey geophysicist Randy Baldwin.

The last earthquake in the region to approach the severity of Friday's temblor was a 5.0 magnitude quake that shook a nearby area in 2002, Baldwin said.

"This is a fairly large quake for this region," he said. "They might occur every few years."

Baldwin said the USGS revised the quake's magnitude from 5.4 to 5.2.
