Several flavors of seismogenic magma movement under Kilauea Volcano

Рет қаралды 54,084

Speaker: Dr. Weston Thelen, USGS Cascade Volcano Observatory
Abstract: Kilauea has long been a target of study because of its high rates of volcanic activity and long history of monitoring. We look at different seismic signatures of magma movement at different places in the upper mantle and crust under Kilauea Volcano. This includes tremor at depths greater than 50 km, repeating earthquakes in the conduit at 3 km depth and seismically derived tilt signals near the surface of the lava lake.

I'm not a volcanologist. Even so, I followed most of this talk with a little help from the Web for definitions. It helped me understand what is happening in the LERZ now (May, 2018 - September, 2018, and beyond). Scientists have some excellent tools to help us all understand what's happening under the earth's surface. The "boots on the ground" work by the USGS staff and others keeps people safe and informed. I appreciate and admire both the theoretical science and the practical applications of what the science reveals. Thanks.

Yes. Good work everyone. The exercise that everyone giving a talk is : Dr Thelen needs to watch it especially the second half. All learners are surprised by watching themselves. And then the next speech will be great-better. I love learning about tectonic geology from someone who knows what they are doing. Thank you for posting this.

Fascinating,thanks for posting. Especially with all of the ongoing volcanic activity. Was wondering where the Kilauea lava chamber is located. Good work in discovering and hopefully future implementation of new data gathering techniques.

Year later after you made this- lava coming out like crazy- people have to leave their destroyed homes- did you think it was going to happen this quick?

Just found this great synopsis of the pre-LERZ eruption. You guys predicted the collapse location in the crater from the tilt observations! Wow... nice work! Do you have a presentation for the latest eruption?! Please please provide a similar synopsis for what is currently happening in the LERZ!

Wes you are awesome! I have been following the recent spasmodic tremor events since January of this year, 2019. Absolutely fascinating seismic signatures!

As we have repeated below, these are not intended to be polished professional public presentations, but rather are webinars by invitation and "in . person" intended as a casual sharing of information for one's peers. We share them to this because the information is valuable beyond the afternoon's audience. It is meant to be conversational, not TV ready performance.

If people were required to view this video prior to building homes on top of the rift zone, I wonder how many actually would have done it. USGS had prior knowledge to the eruptive hazard, obviously. If their employers (citizens) were well educated on the hazard, the destruction of homes may have been much less.

same happening in flood areas, towns want tax revenue and fail to warn people area is flood prone so they build but town has plenty of past info area is in flood danger.

So it looks like the knowledge of fissure 8 presences was known almost 2 years prior to it's surfacing.

9 minutes of actual lecture, 50 minutes of, "um, ah, uh, um, uh, ah, uh, um, ah, um..." "Why do I need to take a public speaking class if I'm studying geology?" And...now you know.

Great information, great work, PLEASE work on the "ums' as they take up almost 40% of the content. :-) We must learn to become public speakers if we are to share Truth in the best way for it to be received. Thank you again ML&R!

This was not a public speech, but an invited talk to a group of colleagues via a webinar. Please understand that this was not meant to be polished and practiced, but a sharing of information. In conversation with friends and colleagues, we allow ourselves a certain amount of verbal pauses. He does very good work, and we were lucky to have him share it.

With HAARP induction magnetometer website shut dow after Fukushima popularity, what induction magnetometer site(s) are available? Who control seismographic data? Is there a live seismographic site set up for the SE portion of the big island?

and now you see what happens when you let PGV plant drill into the volcano... look at the damage they caused

@ellyn8893 5 жыл бұрын

they did not cause this if you had listened it is a pattern that has been established 100's of years before PVG was even thought about!

@Vito_Tuxedo 5 жыл бұрын

There is absolutely ZERO empirical data supporting your speculation that there is any causative link whatsoever between PGV geothermal drilling and the recent eruptive event. Stop pretending you know something for which you have no proof. You’re sowing fear and hatred based on your own ignorance.

Thanks so much. The presentation was very informative. Who cares about a few ahhs and ummms. It wasn’t distracting at all for me and made me feel like I was part of a conversation. Get over it. The world isn’t all made up of perfect Instagram posts and people over-rehearsed or reading TelePrompTers. In fact, I dare say, things are more interesting when they are spontaneous. Geesh....

Its good information, BUT it’s annoying to hear you say A, Ahhhh, aaa, haaaaa, a, a,a, for over aaaaaaaaaaa thousands of times. Maybe try to use other form of vocabulary to pause your speech. Great job, thank you.

It's not a matter of being a Pro but just a good communicator as your knowledge and message deserves. It's very simple, just try to avoid pronouncing pet phrases and swallow them, once you have done it you'll find it's a very easy matter and your speech will sound much better, concise and secure. Well used pauses and slower speech are lot better than useless hmms and ahhhs... ✔✔✔ Anyway, thanks for taking the time for sharing this valuable information ✔✔✔.
