Guest videos: Lava!

There was no time this week to follow up on the planetary calderas, but I think you’ll enjoy these lava videos a lot!

Runny lava

First, there’s pahoehoe (sorry the video is so short):
 


 
Next, a’a lava:
 

 
Pillow lava:
 

 
Sticky lava

And then there is the high-silica stuff that tends to explode…
 

 
…form a dome…
 


 
or collapse into spectacular pyroclastic flows.
