This is a remarkable and big quake, thanks Hal. They are getting stronger.
At 2:54 AM EDT, a very strong Magnitude 6.3 earthquake took place off the southernmost tip of Argentina, in the "Drake Passage" at a shallow depth of only ten kilometers. The quake was so strong, it was felt throughout the entire continent of South America.
The quake is strong enough and shallow enough to trigger a Tsunami, but the location is so far south there are no Tsunami Warning Buoys in the ocean to alert anyone.
The remoteness of the earthquake is noteworthy; almost at the South Pole. Earth generally does not get earthquakes at either pole, yet this one took place.
