This is way more efficient and cost-effective than simply removing an invasive species that preys on threatened, endemic wildlife! Let’s attach tiny helmets to all the petrals next! A bell collar for every feral cat!
2017 is kicking off with some excitement at Hawai’i Volcanoes National Park. Last week a 22-acre section of a lava delta broke apart and sank into the ocean causing the closing of a viewing area. Now, from the new viewing area, visitors can witness a “fire hose” of lava streaming into the ocean. The molten rock sends huge clouds of steam and gas into the air as it hits the Pacific. It’s a sight you’ll never forget. Photos by National Park Service.
“When I went to school, they asked me what I wanted to be when I grew up. I wrote down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life.” - John Lennon
One more lava flow video to close out #volcanoMonday. Pahoehoe lava flowing on the plains of Kilauea - you can watch the surface get slowly crinkled up as the lava cools off at the top then bends the cool layer. Also worth watching - check out how the surface of the lava flow rises up - we call this “inflation” of a pahoehoe field. As lava tries to move forwards, the crust on top holds it back causing pressure to rise and lifting the crust, until there is another lobe that breaks out at the front to relieve the pressure.
This is a lecture/presentation by USGS Hawaiian Volcano Observatory Scientist-in-Charge Tina Neal. It describes and annotates the late December collapse of a lava delta built by Kilauea Volcano, showing both how it works and in fact how it took out a section of land that was even behind ropes and labeled as safe by the Park Service (oops).
