@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!
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.
