NB: The EMSC-CSEM has since issued clarification that the grid pattern results from the rounding accuracy used to plot the quake location. Thus even though the actual quake may have been at a slightly different point, the point plotted on the map will always be at the nearest grid point determined by the plotting algorithm. We are happy to make this clear.

Anybody care to explain this plot of quake locations on the island of La Palma?
