Twitter users were first to have confirmed details and links, even beating the blogs.
Blogs came next, some with concrete details even before local news stations would confirm it.
Radio seemed to have confirmed things next, notably NPR and WAMZ.
Local TV stations were next, confirming the quake and then showing images from links that bloggers and Twitter users posted 30 minutes prior.
National stations were last to pick it up. CNN even showed a map of the epicenter about the “Illinois Earthquake,” but then showed it alongside video footage of the fallen bricks at 309 W Kentucky St in Louisville, KY.
Of course live TV and radio showed the earthquake first, but it’s odd that it took so long to confirm it, considering that info is made available in real-time on the USGS website.
At the risk of being Spammy, here's some highlights from my own Twitter Stream for all to peruse. In order from oldest to newest.
