Botswana: Okavango Delta flow changes direction


How does the flow of the Delta change direction?

A snapshot on the mini earthquakes under the sand by one of our guides, Matsaudi:

We all know that the Okavango Delta is unique. But, did you know that the Delta experiences a mini earthquake nearly every day?  What appears to be a calm and peaceful place is actually experiencing deep-seated tremors underfoot but they are cushioned by the thick sand and mud that lies below the Delta’s surface. It is these shifts that make the ground under the Delta constantly move and it is this process that determines the routes the life-giving water flows as the floods rise and spread out across the reed and papyrus flatlands. New river courses are created and old deep water channels dry up, a constantly changing pattern easily seen as you fly above this beautiful landscape.
