I just saw this from yesterday about a huge landslide in Dorset https://www.dailymail.co.uk/news/article-9467211/Biggest-rockfall-60-years-sees-4-000-ton-chunk-430ft-high-cliff-collapse.html?fbclid=IwAR2FzWq4RK5cNiT9gxQgaURCcj9D6GGEpgUMfF14e-QGw1mzp01-l2W1pLo One might think out loud... now is a good time to go look for fossils in all that fresh rock, but I am sure that this thing indicates that the area is generally less stable than we would all want it to be, as spoken by this official (from the posted link) below. My question is.. when do beach collectors in the UK and otherplaces get back out to these sorts f palces after a landslide? I guess the local officials make these decisions? 'It is a huge landslip, certainly the biggest one I've seen in my 40 years in Bridport. 'I was chatting to some of the people who live by the beach and one man who's been here for 60 years said it's the biggest one he's ever seen. 'By the looks of things there could well be more to come so people need to stay away from that area of the beach.' Dorset Council has warned that further falls are expected - and urged residents to stay clear of the area.

Drone watches as landslide drags houses into the sea on the Norwegian coast
Oxytropidoceras posted a topic in Geology
Freak landslide drags several houses into the sea on the Norwegian coast as viewed by drone.

From the album: Calvert Cliffs
This view of the cliffs in Calvert County, Maryland is gorgeous. I don't often see quite the vivid color range in this formation. I didn't linger, though, and I was wading in the bay to keep my distance. See those trees at the top of the 40 ft +/- cliff? The ones with the roots hanging over the edge? Those aren't going to be at the top of the cliff for long. At this point, they are probably only still there out of sheer habit. We did her a landslide the night we arrived, the spoils of which are in some of the following images in this album. I was on a trip earlier in the year, at a different part of the cliffs, when someone did get hit in the head by a bit of falling clay. Lucky for her, it wasn't a big chunk or from very high up. She *only* had a concussion. If ever you are close to the cliffs like this, watch and listen to where you are at all times. Run like crazy if you hear anything falling! DO NOT TOUCH THE CLIFFS! DO NOT STAND ON THE TOP EDGE OF THE CLIFFS! That prize Meg tooth isn't worth your life.-

I just saw this article online about a school group that was collecting fossils at Lilydale Regional Park near St. Paul. Two kids died when a rain soaked gravel slope failed. http://usnews.nbcnews.com/_news/2013/05/23/18441754-two-children-killed-in-minnesota-field-trip-landslide?lite
