This video shows a huge landslide appear to take out a portion of an entire mountain. It must have been a sight to behold…and the rumbling is quite ominous. The title of the video notes that it took place in Kyrgyzstan in September of 2020, but there is no other info. I also checked the Landslide Blog, my usual go-to resource for this type of thing. Unless I’m missing it, he doesn’t have any info on this landslide in recent posts. It’s possible I missed it, or the video is mislabeled and it took place earlier than September. If anyone knows more details on this one, drop me a note or leave a comment. Thanks to Jim Withiam for sharing this with me.
Mud and debris from a small landslide closed a portion of Sepulveda Blvrd. In Westwood California on Thursday. The slide took out at least one local resident’s backyard and was large enough to block several lanes of the roadway with debris up to 6-ft high in addition to knocking out several power poles and disrupting service. The material was cleared up by 10pm but not before it cause some inconvenience to UCLA basketball fans on their way to watch their team beat Stanford. The LA Times reports that there were questions about possible broken water lines, of course it is the old "chicken or the egg" argument that’s been seen before (including on a recent landslide) about whether the broken water lines contributed to the landslide, or the landslide caused the water line breaks.

The Devil’s Slide Tunnel project is on schedule and on budget according to a news story at ABC7News.com from earlier in June. The video (shown after the break) has a few nice shots showing rock bolting, soil nailing at the portals, and the geologic mapping and laser scanning that happens at the tunnel face.
I also came across a very neat article about how the Ocean Shore Railroad Company was the first to try to cut into the slope along what is now PCH 1 at the Devil’s Slide back in the early 1900s. They were trying to connect the then rural farming community of Half-Moon Bay with San Francisco. The railroad fought the reoccurring landslide and serious rockfalls. Ocean Shore Railroad went bankrupt in 1922 and pulled up its rails, making room for the current highway. (Photo at left from halfmoonbaymemories.com)
