The Anchor cluster is named for Anchor Point at the western end of the
Kenai Peninsula, Alaska. The cluster spans the Cook Inlet. It includes
events in two depth ranges, events shallower than ~25 km, mainly along
the coast of the Alaskan mainland on the west side of Cook Inlet and
events in the range 30-65 km on the eastern side of Cook Inlet, and
beneath the western coast of the Kenai Peninsula. Many events are small
and only observed to regional distances, but all events are observed to
at least 5° epicentral distance. All events have depth control from
near-source and local-distance arrival times.
