Earthquakes of Alaska: 1918 - 2019
The M7.1 earthquake that occurred under Anchorage, Alaska, on November 30, 2018, was the largest earthquake to impact the city in 54 years. It was not, however, the largest recorded earthquake there. That distinction goes to the March 28, 1964, M9.2 Great Alaskan Earthquake (a.k.a. the Good Friday Earthquake) that struck the region as the largest earthquake ever recorded in North America, and the second-largest earthquake recorded anywhere. It in fact released more than 1000 times as much energy as the 2018 earthquake and generated a devastating tsunami.
Alaska and its Aleutian Islands lie above a tectonic plate boundary called a “subduction zone” where the Pacific Plate grinds beneath the North American Plate. This type of plate boundary can create volcanoes, such as those that make up the Aleutian Islands that stretch from Kamchatka, Russia to the Alaska Peninsula. Subduction zones can also produce megathrust earthquakes with large vertical motions that cause devastating tsunamis. Alaska and the Aleutian Islands have been the source of many such earthquakes and tsunamis in the more than 100 years of scientific measurement of these phenomena, and this animation shows all of the recorded seismic activity in this region from 100 years before the 2018 Anchorage earthquake up until the present day*
Some significant earthquakes shown in this animation include:
April 1, 1946 -- M8.6 -- Unimak Island, Aluetian Is. (damaging/deadly tsunami)
Aug 22, 1949 -- M8.0 -- Haida Gwaii (Queen Charlotte Island), Canada (tsunami)
Nov 4, 1952 -- M9.0 -- Kamchatka, Russia (damaging/deadly tsunami)
Mar 3, 1957 -- M8.6 -- Andreanof Islands, Aleutian Islands (damaging tsunami)
Jul 10, 1958 -- M7.8 -- Southeastern Alaska (Lituya Bay rockfall and megatsunami)
Mar 28, 1964 -- M9.2 -- Prince William Sound (damaging/deadly tsunami)
Feb 2, 1965 -- M8.7 -- Rat Islands, Aleutian Is. (damaging tsunami)
Nov 3, 2002 -- M7.9 -- Central Alaska (Denali Fault)
Oct 28, 2012 -- M7.8 -- Haida Gwaii (Queen Charlotte Island), Canada (tsunami)
May 24, 2013 -- M8.3 -- Sea of Okhotsk (very deep: 598 km / 372 mi.)
Jan 23, 2018 -- M7.9 -- southeast of Kodiak Island
Nov 30, 2018 -- M7.1 -- Anchorage (significant damage, no deaths)
The U.S. Pacific Tsunami Warning Center (PTWC) and the U.S. National Tsunami Warning Center (NTWC) will issue tsunami alerts for any potentially tsunami-causing earthquake in the Alaska region. These alerts will be posted to:

*Please note that this animation shows every earthquake in the USGS/NEIC catalog for this region. As the animation moves forward in time so too does the science of seismology with the continual addition of newer and better instruments. As the animation approaches the present day these instrument networks are able to detect smaller and smaller earthquakes, creating the illusion of increasing activity. This effect is especially noticeable in 1973 and again in 2002. In reality these smaller earthquakes have always occurred, but the technology has only recently been able to detect them.

Five Years of Earthquakes in Southern Alaska: 2015 - 2019
Alaska lies above a tectonic plate boundary called a “subduction zone” such that the Pacific Plate grinds beneath the North American Plate. This type of plate boundary can create volcanoes, such as Redoubt, Augustine, and Katmai. Subduction zones can also produce megathrust earthquakes with large vertical motions that cause devastating tsunamis, such as the M9.2 Great Alaska Earthquake that struck Prince William Sound in 1964. A subduction zone boundary will also produce many smaller earthquakes, and they can be seen in this animation as the earthquakes that become deeper and deeper the further away they occur from the plate boundary, the Aleutian Trench. Meanwhile, both plates also host their own shallow earthquakes that result from many smaller faults that form as they are being squeezed and sheared by their collision in this subduction zone. In other words, there is one gigantic fault--the subduction zone megathrust--and many smaller faults on both the Pacific and North American Plates that can produce earthquakes.
For an earthquake to pose a tsunami hazard it has to be able to significantly move the sea floor in a vertical direction, either by suddenly dropping or popping up. Therefore, when an earthquake occurs the scientists in the tsunami warning centers need to rapidly determine an earthquake’s location, including its depth. Is it on land or under the ocean? Is it shallow enough to move the seafloor, or is it so deep that it doesn’t pose a risk? They then determine its magnitude, since a larger earthquake will move more of the sea floor and over a larger area. These parameters can be determined within a matter of minutes. But over the course of the first hour following an earthquake they will continue to analyze their data and they may also be able to determine which direction the seafloor moved. It may have moved primarily in a vertical direction (either up or down), and thus pose a greater tsunami risk. Or it may have moved mostly sideways, posing a lesser tsunami hazard. Once these scientists have this information they can use it to better predict how dangerous a tsunami may be, but until they can figure it out they will assume the worst-case scenario of maximum vertical motion. If they figure out later that the earthquake is something else, such as an earthquake that mostly moved sideways, they may downgrade or cancel their tsunami alert. A graphical way to show this sense of motion for earthquakes is the “focal mechanism” sometimes informally referred to as a “beach ball.” These symbols are included in this animation to show which direction some of the earthquakes moved, especially the larger ones. Note that the locations of the focal mechanisms do not exactly coincide with the circles representing the hypocenters. That is because earthquake rupture starts in one spot then moves across the surface of a fault plane. The hypocenter circles represent where this rupture starts, whereas the focal mechanisms are positioned such that they represent the location of the average of all of the motion from the earthquake. Imagine you’re unzipping your jacket: the hypocenter is where the slider was at the top of your jacket, while the centroid will be somewhere around the middle of the zipper.
Thankfully the largest earthquakes that occurred in the five year period covered by this animation did not pose a significant tsunami hazard because they were too far inland, too deep, not big enough, or moved sideways. Three particularly large earthquakes occurred during this five-year period:
Jan 24, 2016 -- M 7.1 -- east of Old Iliamna, Alaska -- deep with sideways and downward motion
Jan 23, 2018 -- M 7.9 -- southeast of Kodiak -- shallow but with sideways motion (small tsunami)
Nov 30, 2018 -- M 7.1 -- Anchorage -- deep and inland with downward motion but damaging
The U.S. Pacific Tsunami Warning Center (PTWC) and the U.S. National Tsunami Warning Center (NTWC) will issue tsunami alerts for any potentially tsunami-causing earthquake in the Alaska region. These alerts will be posted to:

7.9 ALASKA EARTHQUAKE November 2002 Denali Fault
This quake lasted over three minutes! This was the footage that was seen all-over the world! I called the local station between the main quake and the first after-shock and they put it onto the AP line and I received calls from all over the world asking if they could show the video. This was filmed in the Turnagain area of Anchorage in a house built in 1961; a house that survived the 64 quake, not many in the area did.
At about 22 seconds you can hear my dad complaining of his butt getting wet from the splashing toilet-water... fun. The quakes epicenter was 163 Miles North-North-East of Anchorage.
