Greetings from Norway

Quick Clay exist over large part of the flat lands of Scandinavia, Russia and Canada.
It is normally stable, unless saturated with water and exposed to stress:

That area of Romerike has been investigated to determine area of high risk, where building houses are not recommended, or even allowed:

Internet translated piece:

“Odd Sæther has for the last 20-30 years been a developer for more than 200 dwellings in the area near Ask. He tells VG they have done all landslide protection after the book, and followed the requirements for geotechnical examinations.”

Hmm…

Drone pictures from the landslide area:

It is now frost inn the area and the ground is frozen, but only abt. 2-3 cm. thick, so not safe to walk on in most places affected by Quick Clay that has liquified.

Six bodies found and brought out so far. Work continue with 5 teams of rescuers through the night. Still classified as a “Rescue Operation”.

PS> Most of the affected area appears to be farmland. Only the northern part was built-up area.

It looks like the ‘solid’ ground has just vertically dropped down >10 meters in one big area but not been pushed sideways or up in surrounding areas due to this quick clay phenomena. So where did the missing volume of soil go? Up in the air? Or further down?

One more body found. Now 7 confirmed dead, 3 still listed as “missing”:

The “solid” soil turned to liquid. Some may have floated down the creek and into the nearest river. Nothing has "gone “up in the air”.
Now the rain has stopped. It has turned cold. The top layer has frozen and is more stable.

Here is what happen to Quick Clay when saturated and exposed to any kind of pressure, or motion:

This is similar to what happen to Silica Sand (or many kinds of ore etc.) when transported in bulk and loaded too wet, Bulk ships keep on capsizing for this reason.

Here’s a video that can give some insight on how the soil behaves, where the speaker Ray Archuletta states in the beginning that water infiltration is the result of poor soil function (what may have occurred in Norway):

Rescue operation has now been declared over. That 10 people is dead is thereby confirmed:

Search for the bodies will continue when conditions are safe for the personnel.

On a different not.
It is known as “Bi-sol” ( parhelion) and does occur fairly frequently in some places

Back to something more local.
Today the snow has arrived on the North West Coast of Norway and the temperature has dropped below 0C:

For most this is “business as usual”. Winter tires has been on their car since November and all have been to ice driving training course (compulsory).

Although some foreign trailers haven’t got the required “foot ware”, or skills:

Our son saw three of them in the ditch on his way home from work (1/2 hr. drive) today.

PS> Incl. this one.

Another house with 5 flats disappeared into the abyss two days ago, but it was obviously vacated.
These two houses are so close to the edge that they will most likely go as well:

Some residents have been allowed to move back and those who are still evacuated has been offered free housing in safe area for up to 1 year.

The death toll stands at 10 persons, incl. 2 children below the age of 15.
Seven bodies have been found, three are still listed as “missing, presumed dead”

Hurtigruten (Coastal Express) is back in service on the entire route from Bergen to Kirkenes v.v. (So far, only every second day)
The route plan for 2021 is as attached:

PS> No this is NOT a Cruise Line, but they do carry “cruise passengers” for the entire 11 day round trip, one way, or point-to-point.

The primary reason for this service is to carry cargo and passengers between the ports of call.
It WAS also to carry mail, but that service has now been transferred to air and road transport. (There even used to be a manned Post Office on each ship)

It has been a week on nice cold (-2 -C) winter weather, with blue sky, bright sunshine and no wind here on the NW coast of Norway. (Unusual)
Here is a series of pictures from reader of the local newspaper F.Y.Enjoyment:

(Text in Norwegian can be translated by Google Translate)

Unfortunately a change of weather is expected already late tomorrow. Next week it is expected to be back to normal, with wind, rain and + 2 to 4C or more near the coast.

The northern part of Norway (Troms & Finnmark) has had relatively warm weather along the coast, with no snow on the ground so far this winter. That is about to change next week. Forecast for Hammerfest:

PS> The half-sun that appears in the forecast indicate nice clear weather, but the sun does not get above the horizon
