Two Willsey updates in one day makes it a very good day indeed.
I plan to visit Kilauea in about 2 weeks. I Hope the road is open regardless of eruption or not. Earthquakes can change our plans in a hurry. Would be nice to see an eruption as long as it’s nowhere near any homes.
Thanks once again Shawn.: the 3-d view makes it easy to visualise your analysis of how the magma may have migrated causing the deeper earthquakes.
Thanks Shawn for the update. This is becoming very interesting.
Well done on the shirt!
😀😀😀
Thanks for the information. Your updates are so well done and understandable. Keep up the great work!
Thank you Shawn for the important information, always support your channel ✌️
Thanks!
I like your Hawaiian shirt while updating us on the Hawaiian volcano. 😊
It's a special double-update day! Thanks for updating us on the Hawaii situation too!! Question - I am not clear on the difference between the measurements made by the tiltmeter vs the uplift portion of the GPS... could you address in a future video at some point?
GPS gives you 3D information on the movement of a particular point. If one point moves up relative to another point, the ground surface between the points will become ever so slightly tilted. The tiltmeters are able to measure this extremely small change.
@@timpointing thank you!
I have been following Kilauea for such a long time. It sure is nice to have a geologist explain what's happening.
Two updates today, awesome! Thank YOU, Shawn :) And the 3D view really helps!
Thanks for all the hard work on these videos!
Agree with another commenter. The 3D view is wonderful. Great work in finding and using the available tools.
For those wondering about the tiltmeter measurements - the units are "microrads" or "microradians". These are *very* small angles - over 17,000 microradians in a single degree. As the USGS site puts it: "If you put a tiltmeter on a rigid plank that is one mile long, and then put a quarter under one end of the plank, the measured change would be about one microradian of tilt" (or 1mm in a 1km long plank). Furthermore, the HVO tiltmeters can resolve tilts 200 times smaller - 5 nanoradians! That would, indeed, be the most sensitive carpenter's level ever!
[Sorry. Too much information! My bad! This is why we leave the science/education communication to people like Shawn!]
Great explanation, Tim
@shawnwillsey I'm the TA; you're the prof 😉😁
Thanks for the quick reassurance it's not moving fown past (or even as far as) Pu'u O'o so far.
2018 was one of those eruptions where you feel guilty watching (and listening, when fissure 16 was first clearing its throat) and enjoying the spectacle bc you know it's causing so much heartbreak and hardship for displaced residents.
Thank you.
3-D below the ground is an interesting view. I can’t help but think that the Iceland Svarsengi eruption area will someday have mapping that shows decades of eruption areas, like we see here for the Kilauea area. So cool to see all the visualizations of data. Thank you, Shawn!
I do remember seeing a 3d animation around the November dike formation event i think.
Thank you for this update 😊 Lots going on ☕️☕️☀️🌸
I flew in on the Leilani Gardens fissure eruption. This was a once in a lifetime stroke of luck.
Now I have a better idea how all this happens. It begins to seem like the volcano is alive and moving around through the earth and you can follow it's movements.
Check out Dutchsinse’s info. He is an earthquake forecaster (not a predictor of earthquakes). He actually teaches anyone can use his techniques to forecast earthquakes.
@@orchidorio that's because it IS alive.
The big football shaping earthquake to the far left is fascinating to me because of the size and depth. Thanks very much for your updates.
I was glad to take a break from Iceland!
I noticed for the first time on Google Earth that the Lower East Rift Zone extends 50 MILES off-shore from the SE coast of the Big island, building a ridge that rises thousands of feet from the deep ocean floor. A similar linear feature extends 80 miles to the east of the island of Maui. This is assuming that the bathymetric mapping bears some relation to the actual land form.
The tilt meters measure in micro-radians, or millionths of a radian, an extremely sensitive measurement that can be affected by a heavy rain shower. 10 micro-radians looks like a lot on the graph, but it is like a millimeter in one kilometer or something like that.
1 mm in 1 km would be 1 microradian.
Very informative as always. Thank for sharing! 😊
I'm heading there tomorrow. Hoping to see something special. Aloha! 🌋
Although I live in Kona I try to stay on top of the local activity. I appreciate your updates and just saw a video of the newly replaced chain of craters road and the recent uplift that has caused some cracks and more severe buckling causing some areas closed off.
You do pretty good on your Hawaiian names only got a couple slightly wrong ( university of Hawaii, Manoa has a great native language website for that) .
Any thoughts on the first ever Nankai Trough megaquake alert which was issued following the M7 earthquake in Miyazaki, Japan?
This may become a mega thrust earthquake. Time will tell.
I am very interested in the rift zone, not the volcanic activity so much as the possibility of the rift wideing and separating from the main part of the volcano. I wonder about the possibility of a landfall of the rift zone into the Pacific. As more land is created , ON TOP, is there less support of that land below the waterline, to the point of failure. What is the angle of the slope below the waterline. All that said, I do enjoy the doc on the volcanic activity and its effects on the island. Keep up the good work!
Comments on earthquake swarm 20 miles sw of Bakersfield, CA?
Thanks Shawn I have been following all posts for both Iceland and Kilauea and very appreciative, have you any info on mt Edna volcano?
Thanks for yet another good video Shawn. The audio when you record in your office is becoming uncomfortable to listen to, very tinny. However still sending love from Australia 🌏
So what you're saying here is? The Islands are drifting towards the rift. And that means that they're going deeper in the ocean, right? So that means that the sea level is rising around them because they're going deeper. In the ocean, no, I've been trying to get this Uber to people for quite a while none of the Islands Uber there are getting more water from the ice mountain or anything they're going deeper into the ocean.
👍 for the cheerful shirt!
Thank you!
Kilauea and the Svartsengi magma chambers are competing for attention! Which will erupt lava first? Since these new quakes in the Middle East Rift Zone are still deep, I assume that it would take some time for the magma to break up to the surface.
Hope it doesn't go to the houses again
❤ the shirt
So the magma intrusions, are those what cause the vents/fissures to open?
Mahalo, Shawn! I have 6 acres 9.4 miles southeast of Pu'u Mo'o (BELOW the rim), 4.4 miles northeast of Pu'u O'o (ABOVE the rim), and about 10-12 miles north of the East Rift Zone but still south of HI-11, and certainly love EVERYTHING about lua pele! Aloha noho'i ~ ~ ~ PS: Like I've mentioned to you before, a book on Kilauea (Hale Ma'u Ma'u/Pu'u Mo'o), Pu'u O'o and the rift zones would be AWESOME ~ ~ ~
I am a long time resident of our island away for awhile now..I was last living just after the lava field at Kalapana mauka side. I'm wondering if your maybe directly uphill from there .how do u access? K town side?
@@foresttemple1380 Aloha noho'i, Forest! My little 6 acre plot is in the Puna district (but you already knew that) south of Kokoahi Rd on Uakoko Ct and east of the Kokoahi Rd / Uluhemalu Rd corner sitting just north of Kahauale'a Nature Area Reserve. It sits at 2,565 ft ASL so it's cooler and fewer holoholona lele. It rained there a few years ago for EIGHT WEEKS STRAIGHT never stopping even for a second. TRUE 'rain forest' LOL I DON'T live there as I have a home here in SoCali and I haven't built anything on it yet! Hope you are well and Aloha ~ ~ ~
Kilauea calderon is about 1100m altitude.
Base of Puʻu ʻŌʻō is about 700m.
Fissure 8 at Leilani is about 225m
Ocean is about 0m.
My understandsing is that there is some reservoir about 0m elevation below Klauea.
My understanding is that therte is a straight up pipe from the reservoir to Halama'uma'u and somewhere along that pipe there is a junction to the pipe that goes to the East rift zone.
QUESTION: do we now roughly at what elevation magma that has gone up from reservoir can turn right and enter the east rift zone pipe as opposed to continuing up to get to Halema'uma'u?
During the 2018 eruption, the bottom of Halema'uma'u dropped about 600m down since all the laval that was there disappeared. Would it be fair to state that the pipe junction would be at most at 700m altitude? (1100 - 600).
Or is the location of the junction between the pipe to Halema'uma'u and the pipe to East Rift Zone a great unknown?
@shawnwillsey What is the average ground slope and is there any means of including it on the 3D plot ??
I now live very close to this area. If you need me to run out somewhere with my cameras let me know. Happy to get you some footage.
Also if you have a good hawaii geology site seeing video or could make one that would be awesome. Happy to help you do that if i can.
I have done several Hawaii videos when there. Look in playlists for Hawaii videos.
Thousands of homes up at the upper east rift zone .. The lower east rift zone people aren’t the only ones to worry about the east rift zone magma intrusion …Next will come large earthquakes like in 2018 plus where the magma breaks out to the surface is a mystery … And everyone living below are in danger ⚠️ of fingers of lava heading to the ocean 🌊 with gravity .
Still could mean a possible east zone eruption in the future
From the sound of it could be before years end we see the east side erupt again I’m betting shawn
Thank you for explains a couple of things I was wondering about. Do you feel we may be working towards 😮another eruption In Pu oh oh(spelling I got tired of autocorrect)
Artificial intelligence disclaimer. For some reason, it changes my word. SI have this happen all the time? Everything is typed out spelt, right? After I send it, it makes ruined words in thurgently. It just added a word.I don't know what that is through gently.I don't know what that's supposed to be
Who will erupt first? Hawaii or Iceland!
Wonder if it will punch through another pu u as I asked them if pu u o o would erupt again and they said no it will never erupt again
