Yesterday we had another reminder that earthquakes can occur in the Eastern United States. A magnitude 5.0 earthquake occurred In Canada in the Province of Quebec. The location was 55 kilometers north of Ontario Canada. The interesting thing was the distance at which the earthquake was felt. The USGS Did You Feel It system received reports all over the Northeastern United States and as far west as Missouri and there were even a couple of reports in the Memphis area. The quake illustrates well how earthquakes in the Eastern United States can be felt for vast distances. In 1811-1812 the earthquakes were felt from Florida to Canada and all along the east coast of the United States and as far west (from one report) as Western Missouri.
I've added some new links to the blog. The first one is from the USGS and is devoted to today in Earthquake History. It is a look at earthquakes of the past and their importance. Another link for a Seismological blog from Berkley Seismological Laboratory is from the west coast and looks at earthquakes from that perspective. And finally a couple of twitter feeds for current seismicity. Read and enjoy!
Apologies for not writing in recent times as I have been detained by other more pressing tasks at work. Hopefully the pace will pick up now that I have more time to devote to the blog. More sites will be added to for your reference also.
