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/
The grid is generated for reference. These are deep blot echoes. They appear to be "systematic" when an artificial mapping system is overlayed on it but it is a best guess. Suspicious observers and quakewatch.net have a good video explanation
