Pahoehoe Lava
 |
|
| [Ligne directrice - Note] Note du photographe |
Hawaii is not only the name of the State and Archipelago, but also the name of the youngest and largest Hawaiian Islands, also known as the Big Island. Around one million years old and still growing, it holds a few records in the world of volcanoes. It hosts Kilauea, which is the most active volcano on Earth, Mauna Loa, which is the largest, and Mauna Kea, which is the highest if measured from the ocean floor. All this on an island requiring less than a day to drive around. Needless to say, volcanoes in the Hawai’i Volcanoes National Park are the most exciting part about the Big Island.
This is pahoehoe lava flowing on the side of Kilauea towards the ocean. Pahoehoe is a basaltic, viscous, slow flowing and therefore not overly dangerous lava. Its surface cools and gets covered quickly with a solid black crust, while the interior and the fresh edges remain liquid and are easily noticeable in the image. This is also why the view is not overly spectacular in full daylight, when the red glow is barely noticeable. The view required a two hours night approach over an older lava field, with a very irregular, rough surface. Those who would like to get close to the action should take a few days for this, hike in and camp at the end of the Napau Trail. Walking on lava is quite demanding and the environment is harsh, but the night views are worth the effort.
The picture was exposed 90 seconds and the movement of the stars is clearly visible. |

Hi Roland
I would have liked to see a bit more the sky as I would have found that more interesting than what appears to be kind of a boring part of the photo at bottom. The way you hace captured the lava is awesome man.

cheers .... sarju
PS: Having taken some courses in geomorpholoy, I find this photo kind of stunning .. thanks mate and have a good day/night.

Roland nice work using the time capture in this scene. I see the time exposure was quite a length of time seeing the stars have moved in the scene. I drove all around the Big Island a few years back. Its a gorgous place indeed. Thanks for sharing. I will be back for the rest of your photos of this Big Island. Good work Roland!

Roland, it's quite a treat to see lava from such close distance. Your 90 sec. seemed to have worked very well, the stars are impressive! Informative note, teaches quite a bit about volcanic activity.
Fascinating!

Hi Roland - lava is a very difficult subject to photograph, I think this one did not get much attention so far because people don't realise that, I.m aamazed at how much detail is seen in the black volcanic rocks in the foreground, and at the speed of the stars, 90 sec and that much...wow!!
My favorite of your shots from Hawaii so far.
I can't believe how well the stars appeared in a 90 second exposure, and to capture the movement- awesome.
Night is evidentally the best time of day to capture volcanic action....
Did you bring any marshmallows?

tak jak by komety powodowały wybuchy na powierzchni. Piękna obserwacja :)
