Here is the link to view the grid pattern of earthquakes for La Palma over the last 48 hours. You will need to zoom in on La Palma. I am unfamiliar with how seismic activity is measured in real time. The grid suggests these are not naturally produced, but again, not my field. Thoughts? https://www.emsc-csem.org/Earthquake/Map/gmap.php
I discovered this information this morning from a video posted last night on Bitchute. Here is the link to his video https://www.bitchute.com/video/HOy53HLRTMzN/
That is my exact impression as well. If the island is relatively small, perhaps they have the seismic sensors layed out in that pattern and this dude is just getting excited over nothing.
Edit: found this. Seems to be an artifact of rounding plotted longitudinal and latitudinal data.
