Lava deltas are formed when molten lava stream hits the ocean (happens all the time in Hawaii) and creates new “lava-land” as it solidifies. On November 28, 2005, a rather big lava delta in Hawaii Big Island collapsed … I mean, just vanished into the ocean! Now, lava deltas are infamously unstable, and collapse in minor ways every now and then. What makes this collapse special is that fortunately the USGS caught the collapse on video. A 34-acre delta at the East Lae’apuki ocean entry collapsed over a span of five hours, taking an additional ten acres of land with it to its burial place under the ocean waves. The time-lapse video below is amazing. See it for yourself.
We were on Hawaii Big Island just a few weeks back, and have walked the lava benches close enough to the water. In fact, at one place, we looked over a lava ledge to see the ocean directly below.
Now, thinking about it, when I see this video, it sends chills down my spine.
Boy! this is incredible. I’ve now watched this video 3 times and am still amazed.
Lots of folks write about this matter but you said some true words!!
Fantastically fine document .I just stumbled upon your weblog moreover sought to pronounce that I have thoroughly enjoyed browsing your website posts.After all I’ll be subscribing to your rss feed also I hope you write again shortly!
Before I go, let me thank you for your tolerance with my English as (I’m positive you have figured this at this moment ,), English is not my main tongue consequently I am using Google Translate to figure out what to put in writing what I really plan to say.
