Thanks for the heads-up Leann, and the update Daniel. |
I didn't read my earthquake notification email from the USGS until just now because I was away from the PC since this morning. If this earthquake HAD actually generated a tsunami that made it as far as La Manzanilla, the arrival time would have been a little after 12:51PM local time, so Leann's warning was just in time.
Keep in mind that the warnings generated by the Pacific Tsunami Warning Center use Coordinated Universal Time or "UTC" (previously called Greenwich Mean Time.) The technical/military shorthand for UTC is to follow the 24-hr time with a "Z". The predicted tsunami arrival time at Manzanillo, MX was 1751Z, or 5:51PM UTC. Right now while we are on Daylight Saving Time, subtract 5 hrs to get La Manz local time: 12:51PM. Then add a few more minutes for it to get from Manzanillo to us at several hundred miles per hour: maybe it would have been around 1:00PM.
Fortunately a tsunami didn't happen. Hopefully Costa Rica makes it through this OK. A 7.6 can do quite a lot of damage. The 7.6 that struck south of Tecoman (which is south of Manzanillo) on Jan 21, 2003 killed at least 29 and injured over 300. That one caused a small tsunami of about 1 meter at Manzanillo, and I heard it almost got up into the RV park in Melaque. http://en.wikipedia.org/wiki/2003_Colima_earthquake
