11/29/2006: "4.1 eh?"

So that's what woke me up last night...

Sudbury Star article

Earthquake not likely related to mining
Shaking ground woke residents; no damage reported

Many Sudbury residents were disturbed from their slumber early this morning when the earth shook under them.

Earthquakes Canada reports there was a quake measuring 4.1 on the Richter scale, near Lively at 2:22 a.m. The rumbling was felt at least five kilometres from Lively and across the Sudbury region.

Aftershocks were felt at 2:36 a.m. at two on the Richer scale and 2:38 p.m., measuring 3.1 on the scale.

Further details will be available later today on this website.

The quake was felt in the city's south end , from Minnow Lake and Chelmsford. Greater Sudbury Police have not received any reports of significant damage or any injuries.

Workers at Creighton Mine and the Sudbury Neutrino Observatory were instructed not to go underground this morning as the quake was assessed. Inco Ltd. says the quake doesn't appear to be a rock burst or any mining-related activities, although there is regular blasting activity in the area where the quake was felt, said Marcel Vaillancourt, public affairs specialist.

Creighton Mine is located in the immediate area where the quake was detected. Vaillancourt, who lives in Minnow Lake, said he awoke from the quake and thought a truck had plowed into his home.

Earth sciences professor David Pearson said an earthquake measuring 4.1 is not enough to cause significant damage. Pearson said the quake could have been caused by a glacial uplift. "The land here is still rising after the melting of the ice of the last ice age," said the Laurentian University professor. "So it is rising vertically and every now and again ... some of the old fractures slip a bit."

Pearson said there is about one metre of glacial uplift left.

Here's some more info I've found...

I've never been in an earthquake. . .

Everything is ok at your place, right?

Its funny... I didn't even realise it was an earthquake until I heard it on the news. I probably slept through the 4.1 part, but I sort of remember the aftershock. Nobody was hurt, and there was no damage.

Oh, and the ice storm... that's a bit of an overstatement. It was just some freezing rain that canceled school. I still had to go to work.
