@ai6yr Some screen grabs from the KTLA helicopter feed of the landslide in Sherman Oaks this morning. Thankfully no injuries. Here’s hoping their insurance is current!
@__josh @ai6yr Wow, interesting to see that. I wonder if that's rain, leaky swimming pool, or both. 🤔
@ai6yr @__josh @ai6yr No way to know, could be all, some, or none. My bet is a combination of changes to the slope stability due to the construction of the house above the slide, combined with water infiltration from some source. Only time (and probably a lot of litigation) will tell. Right now I’m just worried about these news crews and firefighters getting too close to the edge. That patio is no longer supported!
@ai6yr @__josh @ai6yr Just a small act of firefighter heroism lol. The news crew is safe for the moment.
@__josh @ai6yr LOL "let's stand at the edge of a gaping maw where the slope is failing and see if it fails while I am standing on it"
@__josh @ai6yr @ai6yr "Let's put this large, heavy pool of water on top of an unstable hill! What could possibly go wrong?" Sigh.

Looks like a big hillside of loose dirt where a bunch of vegetation holding it together has been removed to squeeze in as many mansions and swimming pools as possible. I also doubt many property owners were interested in planting some trees that would block their views and lower the property value.

It's not surprising that a bunch of water (from recent rain or otherwise) would wash away some hillsides.
