Earthquake Park

Highlight • Natural Monument

This small, paved "pavilion" is part of Earthquake Park, which showcases the effects of the magnitude 9.2 earthquake that struck Alaska in 1964. One of the steepest hills on the paved Tony Knowles Coastal Trail is also right here, although it is mercifully short... sort of.

Earthquake Park also has some singletrack mountain bike trails, and a short loop of interpretive walking trail. The walking trail really isn't good for running (it's too narrow, overgrown, and often slippery), and it's best for everybody if runners stay off the mountain bike trails here.

Airport Park (Earthquake Park)

Highlight • Viewpoint

The Earthquake Park reminds and informs about the worst earthquake that hit the North American continent so far.
The quake began on March 27, 1964 at 5:36 p.m. and shook the earth for about four and a half minutes. The epicenter was about 120 kilometers southeast of Anchorage in Prince William Sound. The quake was measured with a value of 9.2 Mw on the moment magnitude scale. A large part of Anchorage was completely destroyed by the quake. The tsunami waves triggered by the quake are said to have reached a maximum height of 67 meters. Only because of the relatively sparsely populated areas, the number of victims, compared to other large earthquakes, turned out to be "low" at 169.
In the Earthquake Park, information boards are used to inform about the quake of 1964, also known as the Good Friday quake or the Great Alaska quake.

Tony Knowles Coastal Trail

Highlight (Segment) • Trail

This section of the paved, multi-use Tony Knowles Coastal Trail is just south of Point Woronzof, a popular location for watching jets land and take off from the nearby airport. The trail here winds through the trees and traverses a couple of long, gradual hills.

Point Woronzof

Highlight • Viewpoint

Just a short side trip from the Coastal Trail is Point Woronzof. You can access the parking area from here, and from the parking area you can descend a steep, sandy trail toward a rocky beach. Watch out for fast-moving high tides, and don't go in the water — there is dangerous, quicksand-like mud hidden under there.

However, locals still love coming here to walk, skip stones, and watch big jets take off and land from the nearby Anchorage International Airport. During the winter, this is a very popular spot for watching the northern lights.

Covering 134 acres (54 ha), Earthquake Park is on the site where a major earthquake hit Anchorage in 1964, causing a whole neighbourhood to collapse into the ocean.
