1Alaska: The number of earthquakes is under reported, even though Alaska already accounts for more than 50 percent of all US earthquakes! Events in the magnitude range of 3.5 to 4.0 in the Aleutian Islands are not recorded on enough seismograph stations to be located.
A major earthquake measuring a preliminary magnitude of 7.1has rocked remote portions of Alaska, the U.S. Geological Survey reports. The USGS issued, then canceled, a tsunami warning for Alaska's Aleutian Islands. It also lowered the magnitude to 6.8.Updated at 11:22 a.m. ET:
Alaska Native Newshas weighed in on the quake, noting that the area "is frequented by earthquakes every day, although a majority of them have a magnitude less than this."
The website, which describes itself as "news for the people of the last frontier," says there have been numerous quakes in the region in the past week, with most of the big ones centered off Kodiak Island, far out to sea.
Newtok, Alaska is not on the southern coastal area. It's due west of Anchorage about 500 miles. Again, I accept there may possibly be some earthquake impact to Newtok. For me to accept this you have to do more than guess but demonstrate this. For example, a Newtok Newspaper reporting the event and commenting how things fell. Don't forget earthquakes can increase elevations as well. So we need the actual event not just guess.Newtok, Alaska has a population of 321. Good luck on getting data for a town that small, as Alaska in general is under reported.
The south costal areas sunk so much in the quake, that the next period of high tide weeks after the quake, caused flooding with additional damage of over $17M Dollars
Wait, earthquakes can cause land to sink? Wow! Wait, Alaska is the most active area in the USA for earthquakes? Must be teh true global warming!
Thanks for your concern. I'm an atheist so I'm clearly not falling for the biggest scam ever, organized religion. Though, I'm not sure how religion got into this thread?The truth is out there faethor, don't fall for the biggest scam in human history!
their preferred encampment, when they passed through the area, was a cluster of sod houses called Kayalavik, some miles further up river. But over the years, the authorities began pushing native Alaskans to settle in fixed locations and to send their children to school.
It was difficult for supply barges to manoeuvre as far up river as Kayalavik. After 1959, when Alaska became a state, the new authorities ordered villagers to move to a more convenient docking point.
The Corp of Engineers said:Newtok’s riverine erosion on the Ninglick River is aggravated by wave action and thermal degradation of the ice-rich riverbank. The long-term, average erosion rate is 71 feet per year, with peak erosion of approximately 113 feet in a single year. The community is experiencing almost annual flooding and has a water supply contaminated by flood-driven sewage spills. Severe damage is expected within 10 years. The community is actively involved in relocating and is pursuing several projects to relocate as quickly as possible.
Newtok, AL
Thermokarst Slumping
Where the insulating layer of plant material has been removed, permafrost melts and the ground above slumps. This is called thermokarst slumping, and it can be a big problem where humans have disturbed the tundra.
building a village, built on a frozen, mud-flats delta, surrounded by a rivers on 3 sides, could be a bad idea
The ground beneath Newtok is disappearing. Natural erosion has accelerated due to climate change, with large areas of land lost to the Ninglick river each year. A study by the Army Corps of Engineers found the highest point in the village would be below water level by 2017. The proximity of the threat to Newtok means that its villages are likely to be America's first climate refugees.
Certainly is a bad idea. Especially when Alaska has seen 4 degree rise in Temp over the last 50 years in their Climate. That change means shorter and warmer winters. Which in turn means more melting of the permafrost. 500 years ago, that wasn't a consideration.
Gerald MacCarthy, in an article published in Arctic in 1953 entitled “Recent Change in the Shoreline Near Point Barrow, Alaska” wrote:
At ‘Nuwuk’ [Point Barrow] the evidence of rapid retreat is especially striking. The abandoned native village of the same name, which formerly occupied most of the area immediately surrounding the station site, is being rapidly eaten away by the retreat of the bluff and in October 1949 the remains of four old pit dwellings, then partially collapsed and filled with solid ice, were exposed in cross section in the face of the bluff. In 1951 these four dwellings had been completely eroded away and several more exposed.
The chart provided is not the winter trend but the Annual trend. The link after the image didn't provide a direct per winter per year measure. Though it did indicate winters are the most changed out of any season by an average of 5.5 degrees, autumn the least, by an average of 1 degree. So would you mind helping direct better where you found/see this data?since 2005 winters have been trending colder in Alaska
since 2005 winters have been trending colder in Alaska
The last 20 years of warming in Alaska proved to be a good place to test Carbon transfer of a changing Climate . What they found is warming indeed releases carbon in a different way. However, it stores it in different ways as well. Making warming fairly carbon neutral. See, one of the hypotheses has been increasing warming will worsen the cycle making carbon release faster. With this more actual research it may not be the case that increasing warming will increase the carbon cycle.
