Our Christmas gift to ourselves was a little trip to the Big Island of Hawaii, something we were thinking (dreaming) about for a long time. There are many great posts about the Hawaiian volcanoes on the geoblogosphere (see for example the ones here and here); I will try to add a few notes and pictures without being too repetitive (and will try to seem less ignorant in volcanic and hard-rock matters than I actually am).
Probably the most memorable experience we had was the lava viewing at Kalapana. This is where 'officially' you can get relatively close to the place where the lava from Pu`u `Ō`ō enters the ocean. The USGS has a nice website with updates on what's going on. I was so anxious to see this place that we had to go there on our first day in Hawaii, that is, on December 22. You have to drive all the way to the end of road 130; there are some big 'No trespassing' signs at one point, but everybody seems to ignore them, and there is an official parking lot at the end of the road, way beyond the 'no trespassing' signs. It is best to get there 30-60 minutes before sunset, and to stay until it's completely dark, to see the potential show both in daylight and in nighttime darkness. Unfortunately, on December 22 we didn't see much, apart from a beautiful sunset and a few small puffs of steam:
That was a bit of a disappointment, but I knew I had to give it another try. After talking to a ranger from Volcanoes National Park, we drove back to Kalapana five days later. This time, the show was definitely on. More than that, it was spectacular. A huge column of steam formed where the active lava tube spills the lava into the sea, and repeated explosions painted red the lower part of the column. From time to time, several tornado-like funnels formed and connected the steam cloud to the ocean.
This was such a uniquely beautiful scene. I wish we went there more than two times, because the whole spectacle changes as a function of the activity of lava flow, weather conditions, the direction and nature of lighting.
I have also learned that it is not easy to take good photographs of fast-moving and rapidly changing distant things in the dark. Here is the proof:
