It isn't much. Probably the first formed from the demise of a tropical
storm east of there the other day. There were 4 centres to the Low
affecting Britain on the Midnight chart. This morning there are only
2.

Makes me think the values given to earthquakes is very far from their
true magnitudes. I think that was a twin or dual. 2 x 3M.

Could even be 2 x 4.5 for all I know:
4.9 M. /03/25 13:00. 34.2 S. 71.8 W. LIBERTADOR O'HIGGINS, CHILE
5.2 M. /03/25 11:11. 35.9 S. 72.9 W. OFFSHORE MAULE, CHILE

What's a 4.9 + 5.2 worth?
