IMPORTANT
This video is circulating about targeted quakes under La Palma . < DON'T WORRY ABOUT IT > Its very misleading, the pattern in the quake locations is a only function of the presentation step size. These observations are not to the accuracy presented and there is a limited number of digits below decimal point in the data.

Go to the site yourself and verify this on any very active location it will be the same. Email the agency if you wish..

It is to be expected when zoomed in!
