Powerful from about a family's tragedy during and after the 2018 Montecito, CA debris flows. At the end of the piece, "We need to learn from natural disasters and how and why they occur. Let's honor their legacy by making things better."

Wow... watch this mudslide in Little Cottonwood Canyon this afternoon.
One massive debris pile hit the road and then another big batch behind it.

Talking with colleagues from and , we saw images just before and after the event from another webcam (skiworldahrntal.it/en/webcams/spe). The boulder came from a point at the top of the grassy area visible at the top of the video.

Looking at the pictures back in time, presumably some construction work in the area may have removed the soil below the boulder, which seems to have been there in earlier years as well.

I compiled mapping of the geology, while others presented solid data ... all have been met with "radio silence" by the media. I'm hoping your expert blog will make the local media sit up and pay attention. (2/2)

This is spectacular boulder slide. Inconveniently, it stopped right in the middle of the road!

Ever lost 300 cartloads of manure? The farmers of Utby did in December 1806 when one of their best fields slid down into a creek valley. The debris was washed out to the Göta River. The landslide scar is still to this day beautifully clear in the geodata (compare below!).

Sadly the loss of life from this event has now reached six people, but "many people are still trapped under the rubble as rescue efforts are underway".

On 18 April 2023, a large landslide occurred at Torkham in Pakistan, close to the border with Afghanistan. At least three people died. It could be that the rockslide was caused by excavation of the toe of the slope and then triggered by a thunderstorm:- blogs.agu.org/landslideblog/
