Earthquake of magnitude 6.5 strikes Alaska Peninsula two months after largest US quake in 50 years


Breaking news: Earthquake with 6.5 magnitude strikes Alaska Peninsula two months after largest quake to hit US in fifty years struck

  • The 6.5 magnitude earthquake struck about 71 miles east of the city of Chignik
  • The depth was reported at 29 miles deep and there was no tsunami threat
  • It comes just two months after a 8.2 magnitude earthquake – the largest to hit the US in 50 years – hit 56 miles southeast of Perryville 


An earthquake with a preliminary magnitude 6.5 struck early Monday off the coast of Alaska.  

The epicenter was about 71 miles (114 kilometers) east of the city of Chignik, the U.S. Geological Survey reported. The depth was reported at 29 miles (46.3 km) deep.

There was no tsunami threat, according to the U.S. Tsunami Warning Center.

It comes just two months after thousands were forced to flee coastal areas after an 8.2 magnitude earthquake struck off the coast of Alaska, marking the largest in the US in 50 years.

While Monday’s earthquake hit 71 miles east of Chignik, the July earthquake hit 56 miles southeast of the town of Perryville, meaning the quakes were around 38 miles apart. 

The earthquake comes just a day another with a magnitude of 6.2 struck south of the island of Hawaii on Sunday, but there was no tsunami warning afterward and no immediate reports of damage. 

An earthquake of magnitude 6.5 struck the Alaska Peninsula on Monday, the European Mediterranean Seismological Centre said

In July, Alaska was hit by a 8.2 magnitude earthquake. The US government’s National Tsunami Warning Center immediately issued an alert for south Alaska and the Alaskan peninsula but canceled all warnings about three hours later.

The maximum wave height detected by the center was eight inches above tide level with small tsunamis hitting at least six points off Alaska’s coastline.

Tsunami warning sirens had been broadcast across Kodiak, an island with a population of about 6,000 people, along Alaska’s coastline. Locals living close to sea level were told to evacuate to higher ground. 

Patrick Mayer, the superintendent of schools for the Aleutians East Borough in Sand Point, told the Anchorage Daily News in July that he was sitting in his kitchen when it started to shake uncontrollably and causes the doors of his pantry and fridge to swing open and empty their contents.  

‘It started to go and just didn’t stop,’ he said. ‘It went on for a long time and there were several aftershocks, too. The pantry is empty all over the floor, the fridge is empty all over the floor.’

King Cove School Principal Paul Barker lives about a half-mile from the school and told the Anchorage Daily News that he immediately started taking pictures off the walls and moving belongings away from the edges of counter and tables. 

‘Everything in my house was shaking,’ he said. ‘It wasn’t that violent. I expected it to get harder and shake more, but it was just kind of a steady shaking for about a minute or so.’

WHAT IS EARTH’S ‘RING OF FIRE’?

Earth’s so-called ‘Ring of Fire’ is a horseshoe-shaped geological disaster zone that is a hot bed for tectonic and volcanic activity.

Roughly 90 per cent of the world’s earthquakes occur in the belt, which is also home to more than 450 volcanoes. 

The seismic region stretches along the Pacific Ocean coastlines, where the Pacific Plate grinds against other plates that form the Earth’s crust.

It loops from New Zealand to Chile, passing through the coasts of Asia and the Americas on the way. 

In total, the loop makes up a 25,000-mile (40,000-kilometre) -long zone prone to frequent earthquakes and eruptions.

The region is susceptible to disasters because it is home to a vast number of ‘subduction zones’, areas where tectonic plates overlap.

Earthquakes are triggered when these plates scrape or slide underneath one another, and when that happens at sea it can spawn tsunamis.
