Earthquake activity has jumped over the last 72 hours primarily due to the 7.2 shake in the Aleutians and numerous aftershocks plus a large uptick of quakes in Mexico's Baja. Many Alaska events are obscured on the map since they've occurred atop each other so a separate map is included. Activity remains steady in "volcanoland" of the Pacific NW. When looking at the legend for these USGS earthquake maps, keep in mind their time frames of "last hour, last day, last week." This can be confusing because any shaker that occurred even 25 hours ago, falls into the "last week" category since their is no daily breakdown.
