This rare early-morning post is brought to you courtesy of the 5.2 magnitude earthquake which woke us up today at 4:37 AM in Chicago.
Here is the live map update of the USGS intensity report, based on questionnaire responses:
The earthquake from a sailing perspective-
Boats already in the harbor should be safe – no tsunami has been reported. Boats on land stored in shock-proof cradles should also be OK.
Interestingly, the North Sails Event Weather Service listserver sent an empty email out to recipients within a few minutes after the earthquake. Note the tell-tale signature 1970 timestamp, an artifact which indicates the host computer time had reset or otherwise been lost, such as waking up from a power outage or other unplanned restart, very likely a direct result of today’s earthquake.
UPDATE 10:19 AM – Aftershock!
Aftershock tremors rumbled buildings again here in Chicago around 10:16 AM. Loose objects mysteriously rattled eerily for a few moments, as if haunted by ghostly poltergeists, and settled down with no evidence or damage remaining. Still, the aftershock also measured a considerable 4.6 magnitude.
