Other than that, we have had some incidental reports of damage to things like appliances and homes and other things. At the same time, a Tsunami Watch was issued for California, Oregon, and Washington. Ultimately, a small tsunami surge, less than one foot deep, was observed in Kodiak and smaller water-level increases occurred in other Alaskan coastal communities. A water-level rise of a few inches was detected four and a half hours later in Arena Cove, California.
She told CNN that students were evacuated after the first main aftershock. ANCHORAGE — Tomasz Sulczynski had been driving for nearly four hours through rural Alaska on Friday when the biggest earthquake to hit the state in half a century began twisting the road beneath him. The airport terminal buildings sustained minor damage to light fixtures, water pipes, and windows. The DOT&PF Division of Facilities Services is conducting building assessments of state-owned buildings in the areas affected by the earthquake. Facilities staff will be working through the night and the weekend to assess damage and prepare for recovery. All DOT&PF Bridge inspectors are now in Southcentral Alaska and are conducting technical bridge inspections this morning.

As part of planned emergency training, the hospital will hold in-house pandemic training this week that includes setting up an Incident Command Center like it did for Friday’s earthquake. The hospital also participates in a pandemic exercise from 8 a.m. As part of that exercise, the community can get free flu shots. Some Anchorage hospitals reported issues with water supply from pipes breaking, but staffing and beds are fine, she said. Hospitals in the Matanuska-Susitna Valley have plenty of bed capacity if Anchorage has a need. All schools in danger of a potential tsunami were evacuated to Homer High School, which was also opened as a shelter for the public.
DOT&PF maintenance and construction crews are actively working the eight major damage sites, located on the Glenn Highway, Seward Highway, andMinnesota Drive. DOT&PF is working with private sector partners on restarting hot asphalt plants in order to pave high priority highway breaks. DOT&PF operations center will continue to issue situation reports. Please expect the next situation report at approximately 9 a.m. Please expect the next situation report at approximately 9 a.m., Tuesday, December 4th. Please expect the next situation report at approximately 10 a.m., Wednesday, December 5th.

Because of this, you can sign up with your personal email and cell phone for texts alerts. Commissioner John Quick announces all state offices in Anchorage, Eagle River, Wasilla, and Palmer will remain closed for business on Tuesday, December 4. The division is using a combination of state trained engineers and contracted consultant architects and engineers, and anticipates additional support from agencies and organizations outside of the state. Employees should contact their supervisor if they need additional clarification on where to report to work Wednesday, December 5. The Southbound Mirror Lake On and Off Ramps are closed this morning. Drivers coming out of Mirror Lake are being detoured north to Eklutna to use Southbound Highway entrance.
Here at DOT&PF, our bridge engineers have understood the threat of an earthquake and have engineered and retrofitted bridges across the state to withstand an event like what we experienced on Friday, November 30. Here are some important facts about state-maintained bridges and what you can expect from our staff as southcentral Alaska continues to recover from the latest quake. All available DOT&PF bridge inspectors are in Southcentral Alaska and are conducting technical bridge inspections on 243 bridges in the earthquake-affected area. Please note, that each bridge is initially assessed by DOT&PF Maintenance, and followed up with a technical review by bridge inspectors. Bridge inspectors continue to work throughout the day and night to complete the inventory. South Peninsula Hospital reported no injuries and no damage from the quake.

Some of those repairs may need to happen immediately and some may happen over the course of several years. Due to ongoing earthquake recovery efforts, public safety and transportation officials are requesting that Alaskans avoid the area of Vine Road that suffered significant damage during Friday’s Earthquake. Engineers and public safety officials are assessing the damage to the area, and unstable ground may put the public at risk. While it’s tempting to take selfies and explore, doing so is unsafe and inhibits the ability of officials to address the situation.
A fault dipping at 29° towards the east gives the best match to the observed seismic waveforms. The depth and mechanism are consistent with faulting within the down-going Pacific Plate. This implies that the earthquake was an intraslab earthquake within that plate, rather than at the plate boundary between the Pacific and North American Plates beneath the Anchorage area.
The National Weather Service and Pacific Tsunami Warning Center initially issued a tsunami watch for Hawaii and the entire West Coast, but cancelled them after less than two hours. In the San Francisco Bay Area, residents within three blocks of the Pacific coast and five blocks of the San Francisco Bay were warned by the city's Department of Emergency Management to be ready for evacuation. Providence Alaska Medical Center kept its ER open and was evaluating damage and water leaks. “I’ve lived in earthquake country my whole life, and this was by far the worst,” he said. It was the first earthquake Anchorage resident Melissa Lohr has experienced. A security camera captured the reaction of a mother as she held her son during the first hit of the earthquake as the chandelier swings in the kitchen.
Residents of Anchorage, Alaska, had barely had begun their workday when the ground began violently shaking Friday. But he also deeply enjoys life in his coastal town, he said; he can kite-ski, kayak, surf, hike. He particularly enjoys long rides along scenic Alaska highways on his motorcycle. The Anchorage fire chief, Jodie Hettrick, urged residents who had experienced any anxiety or trouble sleeping after the quake to pursue mental health services. Aftershocks on Friday night in particular kept many people awake. Alaska became a state in 1959, but it remains deeply misunderstood by many Americans who have never lived there.
The Matanuska-Susitna Borough School District reported that Houston Middle School, located in the town of Houston, was severely damaged, and students were forced to merge with their high school for the remainder of the year. Colony Middle School students were the last to return to learning. Severe damage to several buildings and a highway overpass near Ted Stevens Anchorage International Airport was reported. There were no fatalities, but at least 117 people were injured, mostly for minor injuries such as cuts, bruises or anxiety.
The city announced that regular bus service would resume the following day, and would be free of charge for the two days following the earthquake to help city residents get around on damaged roads. DOT&PF Maintenance and Construction crews are actively working the eight major damage sites . Earthquake aftershocks are continuing to contribute to settling and additional cracking. Hydrogeologic responses to earthquakes have been known for decades, and have occurred both close to, and thousands of miles away from earthquake epicenters. When earthquakes do occur, rapid reporting allows the public and emergency managers to assess the potential impacts.
To request permits, or for any MSCVE relation inquiries, please email The map below shows the locations of damage to DOT&PF highways . Some of these damaged locations have already been repaired and some are scheduled to be repaired in the future. All bridges have been inspected by DOT&PF engineers and have been determined safe for travel. The Alaska Earthquake Center at the University of Alaska Fairbanks is a regional seismic network that participates in the USGS Advanced National Seismic System. AEC contributes seismic monitoring data and conducts analyses that are used in characterizing the 2018 Anchorage earthquake and its aftershocks.
Though volcanic activity causes only a small proportion of Alaska's earthquakes, these earthquakes often warrant more detailed analysis. Ten-hour seismograms from a seismic station on Atka Island on August 6 & 7, 2008. The sudden appearance of numerous earthquakes was an early sign of an eruption that began later in the day on August 7. Not all swarms of earthquakes indicate eruptions; but nearly all eruptions are preceded by vigorous seismic activity. The Alaska Earthquake Center exists to minimize our risks by understanding where earthquakes occur and why. Tracking the earthquakes that occur each day provides clues about the earthquakes that are likely in the future.
