Hi,

I understand this is the mailing list email so I am hoping you might direct this question to appropriate contact.

On June 23^rd, there was a 4.1 earthquake about 130 km SW of Sable Island, Nova Scotia, Canada (42.990N, 60.881W). As someone who lives and works there on a regular basis, and responsible for other island users safety, I was surprised that a notice regarding the occurrence wasn’t initiated. Is that because of the low magnitude (is there a threshold that triggers the notifications) or it’s location or distance offshore (if it is distance offshore is Sable Island recognized as an inhabited place)? Being that the earthquake was on the edge of the Scotian shelf could that have increased the risk for underwater landslide and the potential for conditions similar to those in 1929 which greatly impacted the Burin Penninsula (granted that was initiated by a much larger earthquake at 7.2)?
