Earthquake in Mendoza!
(earthquake map to the left, this quake in red)

In a deep sleep, I was awakened at just a few minutes past 6am by a quite strong quake. It lasted I would guess 15 seconds and was in a rolling motion - I was sufficiently certain that the quake had awoken my colleague Maria, so I called her in her room.... and yes, Maria was wide awake!

I tried to look on-line to find a registry but so far haven't found it listed.... will keep looking, but if it was centered here, my guess it was between a 5.0 and a 6.0. Definitely strong enough but no damage, I'm sure....

Lest anyone forget, Mendoza was famously destroyed by an earthquake in 1861; its wide boulevards and strategically placed plazas were created to allow buildings to crash into the street yet provide space for people and emergency equipment to move around them to the official congregation points - the plazas. The ruins of the cathedral remain to remind the residents of just how dangerous the area is...

The USGS posted this on their website... a 5.1, but at 129.5 miles, very deep in the earth... a good guess by me!
