January to March 2001

Somewhat surprisingly, breakouts continue on the pali throughout the winter of 2001. They are small, but keeping the lava from reaching the ocean as quickly as it usually does. What we do have is a huge pahoehoe sheet flow sitting on the flats below, gradually getting thicker as it inflates with new lava, and slowly spreading towards the sea. Below is a collection of images and video clips from our visits out there through March 2001, showing you some of the subtle features of pahoehoe flows. If you want to see clips of actual inflation, look at our page from summer 2000.

Lava leaks from the inflated front of a sheet flow. Lava inside the flow builds up so much pressure that we've seen it crack open a rock roof over 2 feet thick.
