Magnitude 4.7 Earthquake Strikes South of False Pass, Alaska; No Damage Reported
An earthquake struck the waters south of False Pass in Alaska's Aleutian Islands early on November 6 local time. The German Research Centre for Geosciences (GFZ) initially measured the quake at magnitude 5.0 with a depth of 10 kilometers, centered near latitude 53.69 degrees north. The U.S. Geological Survey later revised the magnitude to 4.7 with a depth of 28 kilometers, placing the epicenter about 139 kilometers south-southeast of False Pass, at 02:35 UTC on November 6. The same waters had seen a magnitude 4.6 quake at 23:04 UTC on November 5, about 147 kilometers south-southeast of False Pass, roughly three and a half hours earlier. The USGS catalog shows 12 reportable earthquakes within 250 kilometers of the epicenter over the past 30 days, the largest measuring magnitude 5.0. There have been no reports of casualties or property damage, and no tsunami warning was issued.
