1452 Odd 6.0 Earthquake Alaska Downgrade to a 3.4? New Zealand EQS
EN English (FR IT PT SP)
22 Mar 2026
A large earthquake in northern Alaska, initially reported as a 6.0 magnitude, was later downgraded to a 3.4 magnitude. The discrepancy between the initial and revised reports is puzzling, as such a significant downgrade is unusual. Despite the downgrade, the earthquake activity in the region remains a concern.
Earthquake activity remains elevated, with a 2.9 magnitude quake in Wyoming and a 5.4 in the southeast Pacific. A meteor sighting near Katy, Texas, caused a sonic boom. The solar flare threat is low, with a 10% chance of an M flare and a 40% chance of a C flare.
Key Points
- Earthquake Report Discrepancy: The Earthmaster noticed a discrepancy between the reported earthquake magnitude (3.4) and the notification received (6.0).
- Possible False Alarm: The Earthmaster considered the possibility of a false earthquake due to limited reports and the questionable nature of the data.
- Investigation Ongoing: The Earthmaster continued to investigate the situation by checking different sources for more information.
- USGS Error: The USGS mistakenly reported a preliminary magnitude of 6.0 for an earthquake near Cakovic, Alaska, which was later corrected to 3.4.
- Earthquake Location: The earthquake occurred near Cakovic, Alaska.
- Potential for Future Earthquakes: The speaker suggests that a larger earthquake in the area is possible due to the high level of seismic activity.
- Earthquake Activity in Northern California: Several small earthquakes occurred, including a 2.9 magnitude event on the Mendocino fault zone.
- Slow Slip Event in Oregon: Six epicentres were recorded along the central coast, indicating ongoing seismic activity.
- Nevada Earthquake Swarm: Continued seismic activity north of Warm Springs, with a peculiar linear pattern observed even in automatically generated reports.
- Meteor Sightings: A meteor was reported near Katy, Texas, creating a sonic boom. Some videos circulating on social media are not authentic.
- Seismic Activity Updates: A 5.4 magnitude earthquake occurred in the southeast Pacific. Older activity was observed near Greece and Italy, while newer activity was detected in the Indonesia and Philippines region, and near North Island, New Zealand.
- Potential Seismic Influences: Large coronal hole activity is currently facing Earth, which may influence seismic activity.
- Solar Activity: Coronal holes are moving away from Earth, with low solar flare activity and a 10% chance of M-class flares.
- Geomagnetic Activity: Unsettled conditions with high-speed solar wind, but a low chance of aurora activity.
- Earthquake Activity: Increased earthquake activity, including three six-pointers, with a discrepancy between preliminary and actual magnitudes.
- Severe Weather Risk: Slight risk of severe weather (tornado, wind, hail) on Sunday in the hatched region.
- Moisture Return and Rain: Return of moisture and potential rain in the southern plains, Texas region, and West Coast.
- Unusual Earthquake Magnitude Change: A large earthquake initially rated at six was later downgraded to 3.4, which is considered strange.
