Lava fountains 2008 |
During breaks in the spattering activity at the hornito, gas is exhaled from the lake surface causing lava fountains. | Fountaining usually lasts about two minutes. It breaks and lifts the shiny, partially solidified lava crust. | Sometimes the gas explodes more violently. Then incandescent lava clots are ejected, looking like an expanding bubble. | The fountains travel across the lake in the same direction as the convective motion of the folded curst (top right). |
Very hot lava continues to rise from the deep magmatic centre of the lake. | Standing only 70 meters above the agitated lake, we sometimes feel very close indeed to all the action! | Highly fluid lava is extended into Pele's hair (barely visible below the centre of the photo). | Lava clots at least one metre in diameter; note incandescent Pele's hair. |
Pele's hair cools quickly and appears darker than the bright lava behind it. | Bright sunlight reflects on the shiny crust, making it even brighter than the fluid lava. | The sun shines on this lava fountain, creating a beautiful contrast to the shadow further back. | Perfect illumination is more important than size, even for lava bubbles, when it comes to making a good impression... |
