I ran across what I think is a fascinating lecture on Kilauea's eruptive cycles. It's a lecture from a geology 205, a course given at UHH. Lots of diagrams too.
I had never heard of "cow patty" lava bombs before.

This lecture may be familiar to students of the volcano like Carey, csgray, dakine, and all you others, but for me it had some new history and observations beyond what I have read in the USGS histories.
It talks quite a bit about correlations between east rift zone eruptions and dropping of the summit lava lake. I am curious what take others have on what it says.
There is also discussion of how little rift zone activity had occurred in the current century at the time the Puna subdivisions were created.
Good stuff on the 1955 eruption as well, and how that magma may have been stored ever since the 1923 events, over 30 years.
