Kilauea Update: No Eruption, Some Refilling of Middle Rift Zone


Update, October 21, 2018: From an October 18th HVO update:

A slight inflationary trend near and east of Pu‘u ‘Ō‘ō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.


Original post:
This VEI 3 eruption, which actually began in 1983 at Pu’u O’o, doesn’t seem to be over yet.



On October 16th, the Hawaiian Volcano Observatory (HVO) reported that ground deformation indicates that the middle East Rift Zone is refilling (current status updates here). This would be around the area of the Pu’u O’o crater.

Recall that this past May, the LERZ eruption that made headlines all summer was preceded by floor collapse at Pu’u O’o, followed by the disappearance of the summit lava lake, which had filled a crack at Halemaumau, the summit crater, that first opened up in 2008.




And here is what the Halemaumau area looks like today. As volcanologist Erik Klemetti notes, much of it slowly collapsed after the lava lake drained.



This volcano is a very dynamic place.

We will just have to wait and see what Pelee has planned next for Kilauea’s neighbors and a watching world. I’ll continue to add significant updates at the Kilauea page linked up top.

Here’s the HVO Kilauea page

New Horizons Opens A Path to Pluto (and Beyond)


Apparently the updates menu goes by the original post date, and this 2014 post is still buried. It shouldn’t be, since New Horizons is now closing in on its next target wa-a-a-a-a-a-y out there on the edge of the our little corner of the Universe. Also, people should check out that 2006 launch video again: that was powerful!


Update, October 5, 2018:

Here is more information on the upcoming Ultima Thule encounter.

Somehow I missed updating this post for the Pluto flyby in 2015. Here is a video that NASA put up about a year ago to show us all what New Horizons saw up close:



Beautiful, but weird! I’m not a musician, but that silent video makes me want to write some music!

Let’s watch the 2006 launch of the fastest spacecraft ever to leave our planet.

Put on your hard hat and watch your speaker volume as an Atlas V rocket, Centaur rocket, and five solid rocket boosters light up.
 

Yeah. That baby took only 9 hours to reach the Moon.

Kilauea: HVO Decreased Alert Level Today


USGS/Hawaiian Volcano Observatory caption for this image (full size image here), with emphasis added:

This wide-angle photo shows the fissure 8 cone (center of image) and the long line of steaming areas extending uprift (west), towards the upper right corner of the image. No significant change was observed at fissure 8 during today’s overflight. Thermal images (see inset lower left) show no signs of lava within the cone – the small collapse pit in the center of the crater floor is cold.

Yay!!!

Per HVO today:


HVO/USGS Volcanic Activity Notice

Volcano: Kilauea (VNUM #332010)

Current Volcano Alert Level: ADVISORY
Previous Volcano Alert Level: WATCH

Current Aviation Color Code: YELLOW
Previous Aviation Color Code: ORANGE

Issued: Friday, October 5, 2018, 8:47 AM HST
Source: Hawaiian Volcano Observatory
Notice Number:
Location: N 19 deg 25 min W 155 deg 17 min
Elevation: 4091 ft (1247 m)
Area: Hawaii

Volcanic Activity Summary: It has been 30 days since lava has been active at the surface of Kīlauea Volcano. HVO monitoring shows low rates of seismicity, steady, relatively low rates of deformation across the volcano, and only minor gas emission at the summit and East Rift Zone (ERZ). These observations indicate that resumption of eruption or summit collapse is unlikely in the near-term.

Accordingly, HVO is lowering the Volcano Alert Level for ground based hazards from WATCH to ADVISORY. This means Continue reading

Update on Popocatépetl

Volcanologists at the University of Mexico released a bulletin (Spanish) this morning; here is the Google Translate version. Click the link in the top menu for more information about Popocatépetl as well as updates.



Bulletin UNAM-DGCS-620

IN INCREMENT, THE POPOCATÉPETL VOLCANO ACTIVITY

• Exhalations and vulcano-tectonic earthquakes have been increasing, because a significant amount of magma is rising, said Ramón Espinasa, from the Cenapred
• The Geophysics Institute placed well seismographs to monitor the activity and predict a major eruption
• Don Goyo has not gone to sleep since December 1994 and the tremor of September 19 of last year, whose epicenter was in a relatively nearby area, affected him, said Ana Lillian Martín del Pozzo, of IGf

The Popocatépetl volcano presents a lot of activity, and is increasing; An example of this is the increase in volcano-tectonic exhalations and earthquakes, the latter of an order of magnitude greater than that seen in the last 24 years.

This data indicates that a significant amount of magma is rising and “within months, a year or the day after tomorrow”, could present an even more important activity than it had, said Ramón Espinasa Pereña, deputy director of Volcanic Risks at the UNAM. the Research Directorate of the National Center for Disaster Prevention (Cenapred).

Meanwhile, in Puebla . . .


See update at bottom of post, or click the Popocatepetl link at the top of this page.


This is a 2011 view of nearby Popocatepetl volcano from downtown Puebla.

Today, people in this Mexican city are watching Popocatepetl with concern (you can follow updates on its activity through the link in the top menu–it has been a bit more restless lately).

Reportedly (Spanish), Puebla State’s Civil Protection director has made a public statement. Per Google Translate of this linked news story:

Although in the last hours and days the Popocatépetl volcano has presented constant explosive activity, with incandescent fragments expelled by the crater, the Civil Protection director of the state of Puebla, Rubén Darío Herrera Cabrera, assures that it is a normal cyclic activity and that there is nothing to worry about.

The incandescent fragments, explained the head of Civil Protection, are pieces of the dome . . .

Even though spectacular fumaroles have been seen in recent days, the largest of which is 2,400 meters above the crater, there is nothing to worry about; “Another point that is constantly monitored is the seismicity and that is totally low, we have very few reports of seismicity, which gives us peace of mind,” said Herrera Cabrera, adding that the volcanic warning light continues in Yellow Phase 2.

This is an image from last night’s explosion as seen from one of CENAPRED’s webcams:


p0923181

This is a night-time image, but the camera is a very good one and the Moon is quite bright. That’s chunks of incandescent material blown out of the crater, not flowing lava. Popo’s lava is very sticky and forms a dome in its crater that eventually pressurizes and blows up–apparently this is the demise of Dome #78. (CENAPRED)

Again, just click on the link at the top of the page for links to more information about Popocatepetl and updates from me.


Update, September 25, 2018: Popo got into a dramatic mood yesterday; updates are at the Popocatepetl link at the top of this page. Meanwhile, here is an eruption the volcanologists monitoring this volcano captured–it’s just one of several yesterday:

Hayabusa2 and Asteroid Ryugu


October 14, 2018, 4:15 p.m., Pacific: This is the rehearsal–they report that the LIDAR problem was fixed, so they’re doing the rehearsal again. There will be another rehearsal later this month.

However, they have moved up the actual touchdown to next year–see this report for details.

Although the first touchdown schedule is changed, we have enough time margins in our schedule, and our aim is a more reliable and safe operation through a comprehensive study of all the sources of information obtained so far during the Hayabusa2 project.

I’m not sure, but there may be another delay of hours now, as there was with the MINERVA rovers, before we know MASCOT has landed and is operating. . .


October 2, 2018, 6:25 p.m., Pacific: MASCOT deployment update: It’s October 3 in Japan, and Hayabusa2 is descending toward Ryugu again, just as it did recently to deploy the MINERVA rovers. Check these Twitter feeds for updates and links as things progress today:

Indeed, good luck, MASCOT!


October 1, 2018: JAXA released this update today:

Hayabusa2 status (the week of 2018.09.24) ★

This week, the MINERVA-II1 rovers that landed on the asteroid last week sent images from the asteroid surface. No regolith was seen in these images, only a shocking scenery of large and small boulders. On the other hand, the scenes of sunlight on the asteroid and the rover hopping were both very beautiful and dynamic. Next week is the deployment of the MASCOT lander. The decent operation is always a nervous time and we want to deliver the lander steadily and carefully. (Regolith: fine grain sediments).

Apparently some asteroids do have regolith.

Meanwhile, MASCOT tweeted yesterday:

Hide From the Wind, Avoid the Water


Update, September 18, 2018: It’s over–the storm, I mean. Now comes the part that doesn’t make headlines, but is so very hard to deal with. If you’re in this situation post Florence, or end up in one like it in the future, take that last sentence to heart: you will make it through this.



Original post:

I lived in West Central Alabama for several years around the turn of the century. As a person from New England/upstate New York, I was clueless about hurricanes and asked neighbors what to do when one came by. They told me to hide from the wind and avoid the water.

It’s good advice, and I wanted to share it as Florence approaches the East Coast. No native or long-standing Carolinian needs such advice, of course, but there are many new people in the places that this hurricane is going to affect who aren’t familiar with such storms.

Your local emergency management experts will give you the best advice, and there is a lot of information coming from the media and reliable online websites like the National Hurricane Center, FEMA, and Ready.gov, but keep that axiom in mind for every situation.

Here are just a few things that I remember from my own experiences and think might be worth sharing.

Hide from the wind
