You can also click any image on this page to access our most updated version of Monday evening’s Anchorage, Alaska’s quake:
As it stands, a violent 5.8 magnitude earthquake shook Anchorage Alaska Tuesday. The quake’s epicenter was more than 47km W of Anchorage. It was just reported from the U.S. Geological Survey that a 2.6, 2.8 and a 2.5 followed the larger very strong jolt that Alaskans just felt.
Chad tells the Guardian Express: “WOW! That sure was a shaker!!! I live in a mobile home, and was scared I would fall off the blocking, but lucky for me, the earthquake-proofing I installed this last summer gave me some confidence, and held things in place well.”
He added, “It was bad enough to knock over flashlights that were standing on end, and other things that had the potential to fall – such as a full can of peanuts at the edge of a counter-top. It lasted a good 30-45 seconds. All you can do at a time like that is “freeze” and say “please, do not get worse, please, stop” and try to use mind control to end it! haha!
Bill was also in Alaska when the ground beneath him began to move. He offered these eyewitness remarks: “If another quake happens after it, how does the 4th quake get incremented to being the 5th quake?
“It actually would have been the forth today but will this article was being written, Alaska was hit with another earthquake.”
The 4th quake was the 5.8 the 5th quake of the day was the aftershock nearby at only 3.0.
As a number of Alaskans already know, The Guardian Express has been on top of these quakes, which seems to be erupting with unusua frequency over the last two weeks.
As we reported last week a series of earthquakes attacked the state of Alaska last Friday. It started with a 2.5 quake 43km S of Tanaga Volcano, Alaska. This quake was followed by a much more signification seismic movement, detected as a 5.0 earthquake 57km west, south-west of Attu Station, Alaska.
The last quake to hit in this series came 12 minutes later and registered as a magnitude 3.1 quake east, north-east of Cape Yakataga, Alaska.
At the time this report was being fashioned, a 3.0 quake hit Puerto Rico.
No news of damage or life lost has yet been reported for any of these earthquakes.
We are still awaiting to see if there was any damage associated with the latest 5.8 quake today.
The U.S. Geological survey has detected 41 earthquakes today, 222 earthquakes in the past 7 days, 857 earthquakes in the past month, and 11,304 earthquakes in the past year.
Alaska is the focus of this report so indeed following information may be useful to residents living there.
According to Alaska’s official seismic website, scientists have recognized that Alaska has more earthquakes than any other region of the United States and is, in fact, one of the most seismically active areas on the globe. In fact, the second largest earthquake ever recorded shook the heart of southern Alaska on March 27th, 1964, with a 9.2 magnitude quake. This earthquake was slightly larger than the magnitude 9.0 Sumatra-Andaman Islands earthquake that devastated northern Sumatra in December 2004 and generated a tsunami that killed more than 280,000 people. The largest on-land earthquake in North America in almost 150 years occurred on the Denali fault in central Alaska on November 3rd, 2002, with a magnitude of 7.9. So perhaps it’s not so unusual for earthquakes to occur in clusters in Alaska.
Alaska’s 1964 quake resulted in property damage, which was the largest Anchorage had experienced. In addition, the quake caused significant landslides. This mega-thrust earthquake also triggered a devastating tsunami that caused damage along the Gulf of Alaska, the West Coast of the United States, and in Hawaii.
The Guardian Express is currently monitoring news from the region and will bring you updated information once it’s available.
D. Chandler contributed to this report.
If you recall, he brought Alaskans news last Friday night as a 5.9 magnitude earthquake shook the region, but there are no reports of damages. The strong quake struck the Alaska Peninsula/ South Central region with a great deal of strength. It wasn’t like the mild succession of quakes that occurred Thursday.
The Alaska Earthquake Information Center says the quake was widely felt.
Jeff Antill wrote to us saying, “I felt and heard the 5.8 quake here in anchorage. Our roof is heavy timbers and it makes alot of noise in even the smallest quakes. This one shook everything quite well.”
On the other hand, Chris Bryant says, “It wasn’t too bad. It felt like somebody was running on the deck outside. I only knew it was a quake because of the vibrations left over after the initial jolt.”
The Kodiak Police Department says there were no reports of damage or other problems early Saturday.
A quake of this size has the capacity to cause considerable damage under some circumstances.
The quick jolt occurred 69 miles north of Larsen Bay and 238 miles southwest of Anchorage. It was generated at a depth of 52.1 miles beneath the surface on the mainland across from Kodiak Island. The location of this earthquake was equidistant between the long quiet region of Devil’s Desk and Kaguyak Volcano. Devil’s Desk is a volcanic neck of a former stratovolcano now completely surrounded by Hook Glacier. Erosion has removed most of the stratovolcano. Wes Hildreth of USGS as well as others state that Devil’s Desk was active 292,000 years ago to the Holocene.
Kaguyak Volcano is another stratovolcano that had its last major eruption about 5,800 years before present, and has been largely quiet since that time with no recent eruptions or activity for at least the last 1,200 years. The National Oceanic and Atmospheric Administration’s West Coast and Alaska Tsunami Warning Center issued a statement advising that there was no tsunami danger from this quake.
The Alaska quake was first reported as having a 5.6 magnitude energy level, however, seismologist changed it to a 5.9 in the last hour.
Again, will keep you posted with the latest news about the violent eruptions going on in Alaska in recent days, including today’s powerful quake.
