According to the USGS geek squad, this is even more dangerous than it looks...DUH!
This video was posted by Hawaii native Kawika Singson. He normally takes a lot of photos of Hawaiian wildlife but one day while shooting inside the "Lava Zone" he saw this guy swimming. He appears to be on a surf board and you can see the current taking him in an out...CLOSE TO LAVA.
Watch for yourself. Again, You gangsta AF if you swim with LAVA.
