Japan Mudslide (General)
BBC: Twenty people are missing in central Japan after a huge landslide hit Atami city following heavy rainfall.
This looks horrific - video below of the moment a mudslide tore through Atami in the prefecture of Shizuoka.
Assuming this was from a plum rain event - they seem to be getting more destructive in Japan in recent years.
Reports say up to 800 mm fell over a 72 hour period - things are gonna give at that level.
