Landslides in Brazil 

One of my favourite web sites - https://blogs.agu.org/landslideblog/ - has produced three articles about the recent landslides in Brazil. You can see them HERE, HERE and HERE. This is not particularly geological but still fascinating. 

The lesson I take is do not build your house on a steep slope where there is heavy rainfall! Looking at the videos one realises that these are not slums but fairly well off areas - lots of cars, mobile phones. 

The cause of the landslides was extraordinarly heavy rainfall rates of more than 100mm per hour were recorded.
