Strong earthquake at intermediate depth close to Anguilla, Leeward Islands - December 24, 2017

Update 15:52 UTC: This earthquake will  NOT generate Tsunami waves as the Magnitude is not powerful enough (besides a couple of exceptions, the Magnitude needs to be at least M7 of higher).

Update 15:34 UTC: USGS epicenter

Screen Shot 2017-12-24 at 16.34.14

Update 15:31 UTC: USGS has decreased the Magnitude to M5.2 what better corresponds with the shaking values we receive from the earthquake area. Because of this we are lowering our damage expectation to :
Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, does not expect any damage from this earthquake

Update 15:27 UTC: Due to the depth of the hypocenter, the shaking will be seriously weakened compared to a shallower depth

Update 15:22 UTC: Based on the present earthquake parameters (Magnitude, Depth, Population, etc) and our experience with earthquake damage impact, does expect at least some slight damage like cracks in walls, fallen tiles, etc.
