6.0 Magnitude Earthquake Strikes Alaska on Thanksgiving Day, Tremors Felt from Anchorage to Fairbanks

Alaska earthquake: A powerful earthquake shook the US state of Alaska on Thanksgiving Day. At 8:11 am local time on Thursday, 27 November 2025, a 6.0 magnitude earthquake struck near the Susitna region. According to the United States Geological Survey (USGS), the epicentre was located about 14 kilometres northwest of Susitna city and was recorded at a depth of approximately 69 to 80 kilometres beneath the surface.

Being a moderately deep earthquake, the impact was felt across a wide region—from Anchorage to Fairbanks. While no major damage or loss of life has been reported so far, residents expressed concerns and panic was witnessed in several areas.

Strong Tremors Send People Outdoors

The tremors were strong enough to force several residents to rush out of their homes, even as many were preparing breakfast. Videos shared on social media showed household items falling from shelves, cracks developing in drywall sections, and loud rattling of utensils.

Authorities later confirmed that there was no severe structural damage. Anchorage Mayor Suzanne LaFrance stated that preliminary inspections of public infrastructure—including roads, bridges and tunnels—showed no significant impact. She said, “Initial reports indicate the city remains safe, though precautionary monitoring will continue.”

Authorities on High Alert, No Tsunami Threat

Soon after the earthquake, the Alaska National Tsunami Warning Center assessed the situation and confirmed that there was no tsunami risk associated with the event. This brought relief to residents in coastal regions.

State officials began a comprehensive survey following the earthquake. Roads, bridges, gas pipelines and power grids are being closely monitored to identify any possible damage.

An official said, “Although the earthquake struck at a deeper level, we must ensure no infrastructure remains vulnerable. All departments are alert round the clock.”

Warning of Aftershocks: Minor Tremors Continue

Seismologists have advised residents to remain cautious, as aftershocks are expected in the coming days. USGS estimates indicate a 28 percent chance of another quake measuring 5.0 magnitude or higher, while there is a 97 percent chance of lighter aftershocks (3.0 magnitude or above).

Within hours of the main event, minor aftershocks measuring 2.7 and 3.2 were recorded. Experts say such activity is normal as tectonic stress gradually releases after a major slip between plates.

Alaska is one of the world’s most seismically active regions, witnessing nearly a dozen moderate quakes and several above 7 magnitude every year. The 1964 Alaska earthquake, measuring 9.2, remains the largest in US history.

‘Susitna Quake’ Trends Online

Shortly after the tremors, hashtags such as #AlaskaEarthquake and #SusitnaQuake began trending across platforms including X (formerly Twitter) and Facebook. Many residents shared CCTV clips showing shaking crockery, swaying picture frames and frightened pets.

A widely circulated video showed a child waking up suddenly and running towards parents in fear, drawing emotional responses online. Several locals said the shaking lasted nearly 20–25 seconds—longer than usual.

Strongest Quake Since 2021

According to experts, this was the strongest earthquake recorded in south-central Alaska since 2021. The earlier tremor near Anchorage had caused minor damage to buildings. Differences in depth and fault behaviour meant that this latest quake affected a wider area but resulted in comparatively less destruction.

Geologists explained that tectonic pressure accumulates over long periods beneath the earth’s crust and releases suddenly as earthquakes—an unavoidable natural process. However, preparedness and timely response remain crucial for public safety.

No Link to Indonesia Quake

Interestingly, the Alaska earthquake occurred just hours before a moderate tremor in Indonesia. Scientists clarified that both events were unrelated, as Alaska and Southeast Asia lie on separate tectonic boundaries moving in different directions. The timing, they said, was a mere coincidence.

Community Alert Continues

The state disaster management agency has urged residents to stay prepared, check their gas and electrical lines, and follow safety guidelines. Schools and offices have resumed earthquake-readiness drills.

Many schools reminded students of the “Drop, Cover and Hold On” safety method—encouraging individuals to take cover under sturdy furniture until the shaking stops.

Amanda Grey, a resident, said, “Living in Alaska means earthquakes are part of life. But each time it happens, it reminds us how important preparedness really is.”

Nature’s Power and Human Preparedness

While the Alaska earthquake did not lead to major destruction, it has once again highlighted the state’s geological vulnerability. Experts have repeatedly cautioned that the possibility of stronger seismic events cannot be ruled out in the future.

Fortunately, this incident caused no serious harm. Quick administrative response, public awareness and monitoring systems ensured stability. However, officials and experts maintain that preparedness for natural disasters is an ongoing responsibility that must never be taken lightly.
