Alaska has quakes each and everyday.
Volcanic arcs and oceanic trenches partly encircling the Pacific Basin form the so-called Ring of Fire, a zone of frequent earthquakes and volcanic eruptions. The trenches are shown in blue-green. The volcanic island arcs, although not labelled, are parallel to, and always landward of, the trenches. For example, the island arc associated with the Aleutian Trench is represented by the long chain of volcanoes that make up the Aleutian Islands.

What the heck is going on? Is this normal?
I think something big might be happening.
When the northwestward migrating Pacific "plate," as it is called, reaches the Aleutian Trench, it is absorbed back into the earth. This downwelling process is what produces the earth's oceanic trenches in the first place[...]Although it is not well publicized, primarily because the population density of the state is so low, Alaska produces approximately twice the number of earthquakes than all the other states combined. Nearly all of these are directly or indirectly related to the state being rammed from the south by the marauding Pacific plate.
