Alaska Hit by 6.9 Magnitude Earthquake Two Months After America’s Biggest Ever Quake

by Taylor Cunningham

Early this morning (October 11th) Alaska woke up to a 6.9 magnitude earthquake. This comes only two months after the US felt its biggest earthquake in 50 years and only one day after the Hawaiian Islands had a quake with a similar magnitude.

The tremor struck about 71 miles east of Chignik, Alaska. And according to the U.S. Geological Survey, the epicenter’s depth was 29 miles deep. The quake affected people who live along the Alaskan Peninsula and on the Kodiak Islands. And the U.S. Tsunami Warning Center confirmed that residents are under no immediate threat of a tsunami.

Alaska’s earthquake followed a 6.2 magnitude event that struck south of Hawaii’s big island on Sunday. The islands are also not under a tsunami threat. And there were no reports of serious damage. While there is a slight chance that Sunday’s tremor triggered today’s, officials believe it’s unlikely.

Today’s earthquake is actually an aftershock of July’s 8.2 magnitude earthquake, which happened on July 28th only 38 miles from today’s epicenter. That event was the strongest quake to hit the US since 1965. That year, the western Aleutian Islands felt a massive 8.7 quake.

While it may seem odd for an aftershock to rumble months after an earthquake, the US Geological Survey’s Earthquake Hazards Program says it is a normal occurrence. They can continue for years after a large earthquake.

Tokyo October 7th Earthquake Marked Region’s First Seismic Activity Since 2011 Disaster

Last week, Tokyo was struck by a powerful 5.9 magnitude earthquake. Thirty residents were injured during the event. And three of those people are in serious condition. According to the Meteorological Agency, the tremor’s epicenter was just east of Tokoyo in the Chiba prefecture. And it began at a depth of 48 miles. The earthquake was the area’s first record of seismic activity since 2011.

The October 7th event did not cause any major damage within the region, and the city had no threat of a tsunami. But the tremors did cause a brief moment of panic. ABC News reported that Tokyo’s building swayed violently during the quake, and the force caused underground pipes to burst. And around 250 homes were left without power.

The earthquake also caused trains, subways, and elevators to temporarily shut down. One commuter train partially derailed as the conductor pulled the emergency brake. Three of the train’s passengers suffered minor injuries.

Because most of the city’s express trains had to pass safety checks before resuming operation, Tokyo had major travel delays and disruptions. By Friday, most trains were cleared, but residents were stuck waiting in long lines due to schedule delays.
