Description: The article concentrates on the popular topic which is related to active volcanoes in hawaii. It mentions the eruption of Hawaii Volcano Kamoamoa fissure six months ago, the author is going to talk about some eruptions events of volcanoes showing us the pictures of the lava and the land taken by the people on the helicopter.
Six months ago, today the steady eruption cycle at Kilauea Volcano changed when this incredible fissure, tour opened the ground in the middle-east rift zone before that the public had known the most recent eruption activity through its summit lava lake.
An active ocean entry at Kalapana and restless pool crater in between homes in the Kalapana garden subdivision were on alert, but when the earthquakes on the rift zone began to rattle the area continually, it seemed that a change was coming scientists in charge Jim kauahikaua for several months of earthquakes decent sized ones magnitude three or so.
But the sign that something had started tilted and we have most of our important data streams alarmed, so we get text messages or emails or something and one of our data streams we have, it also cooked up to an automatic dialer, so it will call our phones in case internet doesn’t work.
But we all know what our jobs are and basically once everybody hears that an event is going on, we all look at our various data streams, the first thing that happened was that deflation till meter on the North flank and that kind of alerts you to look at the camera, you see that the floor is dropping out from under it.
When the first video of the March 5th kamoi MOA Fisher was released, the world got a glimpse of the power of Kilauea commonly known for its peaceful eruption, but as geophysicist Mike Pollan explained at a recent after dark at the park talk at Kilauea visitor center, this video captured by a heroic Hawaiian Volcano Observatory scientists was nearly more than was bargained.
So we sent out this geologist in this helicopter and the over flew boot wall and noticed that the crater floor is gone, but he didn’t notice anything else in his first pass and then he was over that, the pilot looked over their shoulders a little bit up rift.
They saw a fissure eruption that had started, so what did they do? Like any good geologist, he landed, he took a video, checked this out, this is what he saw, keep your eye on this area here, it’s starting to steam and on this area here, the cracks are getting bigger, you’ll see chunks fall in and you’ll see now it’s starting to spatter there.
More and more gas are coming out, a big chunk is about to fall in, here you can see lava there, here goes the big chunk, there’s the spatter, it’s time to move for a volcanologist, this is about the coolest thing in the world having a fissure eruption, that’s stunning, the first journalists who capture the images of the combo amo eruption was Vulcan ographers Mick Kalber who brought the world.
This defining footage for Mick a moment like this will never get old, it’s a visceral experience to watch this, you know it’s so organic, it’s the birth of the earth, if this is still a thrill for a volcano veteran like Calbre, imagine what Marco Hernandez thought filmed that same night by Calbre flying this helicopter in the foreground, it was fernanda’s first charter flight over a Hawaiian Volcano.
Everybody was happy for me, I think to have that on my first day, I didn’t have much to compare it to and had any experience with volcanoes prior to that, but seeing that eruption who I knew it was something special and as the other helicopter showed up on the scene, as there are lots of talk on the radio very quickly.
I heard people who have been flying out here for 15, 20 years that they have seen this stuff for the first time, they’d never seen anything like it and I heat in quick, this was special by the time I got there, Calvin joined, my boss was already there in one of our other helicopters at 4:07 with a film crew and they were doing film work and I happened to be at the right place, the right time and got some neat photos of the Hewes 500 with the volcano in the background.
But that wouldn’t be Marcos last, look at a major eruptive event, he took caliber up in the helicopter a few months later to help capture the most recent event breakout in August with the incredible March 5th Comeau amo, a fissure eruption on the east rift zone attention was diverted from Kilauea usually show at the summit.
But when the lava lake at Halema’uma’u drained away, some recalled the worst case concerns of an explosive eruption, the disappearance was similar to the accounts of a lava lake draining in 1924 that resulted in a violent summit eruption that caused one person’s death and doubled the width of halima MO or worse the 1790 explosion that is believed to have killed over 80 Hawaiians who were travelling some miles away.
Scientists say that thankfully the events were different in a very important way, there were important very important differences to the two events, this withdrawal of the summit lava lake was in no way similar to the one and nine in 1924, the lava lake had drained weeks before the explosive eruption.
So it was speculated that the lava had withdrawn below the local water table which is rather high and at that point, we see that when the lava recedes, it weakens the walls and the wall star collapse, so the idea in 1924 is that lava must have receded below the water table allowing water to enter the vent.
So the explosions were what’s called phreatic basically groundwater flashing into steam and exploding metal now that six months have passed, what do scientists have to say about the spectacular komomo fissure eruption? They’re all spectacular and probably the most spectacular one will be the last one, the most recent one.
If you’re scientist in charge Jim kauahikaua one word could be cool that one was cool, so I was out there 97 when the previous one occurred in that area, that was only a little less than 24 hours, this would go on for four days and that was part of the coolness and that we knew what had happened in 97.
So we were on it with the komomo Fischer doing the mapping and Amanda sampling and we got a good data set out of that helped us figure out what went on data that as geophysicist Mike Pollan says helps define what appears to be a definite pattern at pool.
One of my colleagues described this as the Easter us on how to conduit aneurysm maybe a little graphic and colorful, but it’s not a bad way to describe this, the conduit ruptured magma had to get out there and is perhaps not surprising that it happened there, because historically, that’s the most active part of the east rift zone, it is the weakest link in the house that it is the weakest link in the rift zone.
We’re still sticking magma into to Kilauea, it’s got to go somewhere and now it’s filling pool, so I said this a few times and I’m not afraid to say it again, this is only going to end one way promising that the show is far from over at Kilauea Volcano.
