Volcano watch 2010

Not much going on with this thread lately....hard to keep up with everything!

So ofcourse I keep going back to the volcanic range in my back yard, but I really am a little confused over the latest seismos at Rainier. She continues to be active, with three quakes listed so far just for today. I noticed these wierd signatures a couple of days ago, but figured it was just something wierd going on locally. However, it is intesifying and now there are recordable quakes.

So check out THIS seismo for Rainier. HERE is the link to the main list.

If you go to the main list and click through all the Rainier stations, you will find this on three of them, this repeating....noise. I'm not sure what it is. They look like very sharp spikes...either like very small micro quakes that aren't even registering, or maybe something local like rocks falling.

It appears to start on the 18th and pick up in frequency and strength. I haven't seen this signature there before and it seems to be intensifying so I'm looking for some educated opinions? (or otherwise...)

your right about Mt Riener , it does seem to be picking up , did you happen to find out when the last time she erupted was ? if not i can and post the links here .

Mt Rainer last erupted in 1894 , so its been over a 100 years ,

here a before eruption pic of Mt Rainer,

[edit on 22/5/10 by alysha.angel]

I'm still not convinced Mt Rainier is up to much. (Or maybe I just choose not to be because I live too close.) Some of the small stuff you see on the graphs I think is weather related. The weather here has been extremely unpredictable for the past week.

But there's quite a vigorous earthquake swarm going on yesterday and today at Long Valley, take a look at the seismos:

Here are some more versions of the recorders on the EHZ or ENZ channel instead of the SHZ channel.

RER.UW..EHZ.2010.142
RCS.UW..EHZ.2010.142
SMNR.UW..ENZ.2010.142

RCS (Camp Schurman) is interesting as this seems to have the most 'noise' and is pretty much at the top of Rainier. Looks like a lot of micro quakes. Sounds like......

1000 Hz version wave file 2.1 Mb (10x speed)
4000 Hz version wave file 2.1 Mb (40x speed)

These are also available in the Yellowtone folder on 4shared in the 'Sound Files' folder

Lots of popping. The sharp pops are local micro quakes I think, since I can't think of anything else that would cause those noises at that elevation.(2877 mt)

reply to post by PuterMan


Thanks for the info Puterman. I knew you'd come through!

Micro quakes is what I was thinking, without 'listening' to it though, or seeing it on another clearer source, I just couldn't be sure it wasn't weather related.

Once the recordable quakes yesterday started to show up, it kinda confirmed my suspicions.

SO...now, my question is this: What do you think about it? I need to take some time tonight and go back through some historical seismos, if I can find them, to look for anytihng similar. I just have absolutely NO idea if this means anything significant at all. I can't recall ever seeing this many of those signatures ever before. I have noticed some sporadically, but not THIS much.

I have been paying a bit more attention the past few weeks because of the off-shore quakes, Mt. Hood's swarm and ofcourse, Iceland. Now....on May 18th there were ofcourse several news stories about Helen's because of the 30 year anniversary. They had a local geologist interviewed who didn't want to talk much about Helens...but Rainier. He was saying how the real concern isn't Helens, but the much larger and deadlier Rainier. It just got me to thinking more about it and now all these quakes...hopefully it is something benign and not out of the norm.

Check Katla today, she's showing as having activity.

Description:

In the past 48 hours 3 earthquakes occurred at Katla volcano, Iceland. The earthquakes may be due to ice movements within Mýrdalsjökull glacier or magma movement under the volcano. Scientists have been keeping a close watch on Katla volcano, due to the possibility of an eruption triggered by the activity at nearby Eyjafjallajokull. An eruption of Katla volcano has the potential to be more devastating than the current eruption of Eyjafjallajokull.

I have plots stored for day s 87 and 89 (Julian) and the microquakes are there as well underneath all the other noise, and just as many of them, so I guess at least from those two days it would seem nornal for Rainier.

Look at this and read the top of the plot. When that message goes - worry!

Vanuatu's Volcanoes have Awakened -

Fantastic Video

Could this be due to low sunspot activity?


22 May 10 - Look out Australia! Trouble is brewing in Vanuatu. A Vanuatu eruption could blast a tsunami toward Australia.





"In the past few weeks, the level of activity has increased markedly," says volcanologist John Search in this fantastic video. "Something big
could happen any time. People don't take
volcanic eruptions seriously enough."


"Australia should be realistic," says Search. "Tsunami can be bigger than the Sumatra
tsunami in 2006. The largest tsunami have
come from volcanic eruptions."


"In recent months they've awakened," say islanders. "All of the volcanoes in Vanuatu are excited right now. You can feel the movement underneath your feet."


This week while attending the Heartland Institute's 4th International
Conference on Climate Change in Chicago, I asked Dr. Habibullo
Abdussamatov, head of space research at the Pulkovo Astronomical
Observatory in St. Petersburg, Russia, if low sunspot activity could
trigger volcanic activity such as that in Iceland or Vanuato.


Dr. Abdussamatov said, "No."


But considering my contention that tectonic movement is driven
by electromagnetic forces (see "Not by Fire but by Ice"), I can't
help but think that there must be a connection.

Things getting busier at Baru Jari (Indonesia)

An active volcano has erupted in Indonesia, spewing ash up to two kilometres into the air. Ash from Mount Baru Jari on Lombok island, near Bali, has damaged crops but the volcano is not threatening villagers. It erupted three times from Saturday night until early Sunday according to Mutaharlin, the island's volcano monitoring official. Lava flowed into a lake, pushing its temperature to 35 degrees Celsius, up from 21 degrees Celsius, while smoke spread 12 kilometres.

I can't see anything about this so I'll post it..

COSTA Rica's Arenal volcano has erupted, spewing geysers of lava, ash and toxic gases from its crater and forcing the evacuation of the national park where it is located. The 1633-metre-tall cone-shaped mountain in northern Costa Rica shuddered into activity at 4am this morning issuing eight successive rivers of lava that flowed down its steep slopes, National Volcanology and Seismology Observatory expert Elicer Duarte said. He said nobody was at risk from the eruptions but authorities as a precaution evacuated the Arenal National Park, 80km north-east of San Jose. The Arenal Volcano is one of Costa Rica's major tourist attractions and the park has scores of hotels, restaurants, nightclubs and shopping centres. No estimates were given of how many people were inside the park when the eruption began. Arenal's last major eruption in July 1968 killed 89 people. Smaller eruptions have occurred at least six times over the past 35 years.

For all of you going into withdrawal now that Eyjafjallajökull seems to have quieted down, there are two eruptions of note that aren't in the North Atlantic:

Here's another volcano to keep your eyes on - although it could be a couple of years - it's now showing signs of an eruption...

MAY 25 2010 Mountain Baekdu, a dormant volcano on the border between North Korea and China, is showing signs of a possible eruption in the near future, experts warned Tuesday. "Baekdu could erupt anytime soon," said geologist Yoon Sung-hyo at Pusan National University, who has monitored the nation's highest mountain (2,744 meters) for any changes. "A variety of indicators are backing this scenario. The thing we should try to predict is when. It's clear it's imminent." The geologist cautiously raised speculation that an eruption could take place in a couple of years.

[It's just information!] Mountain Baekdu, a dormant volcano on the border between North Korea and China, is showing signs of a possible eruption in the near future, experts warned Tuesday. "Baekdu could erupt anytime soon," said geologist Yoon Sung-hyo at Pusan National University, who has monitored the nation's highest mountain (2,744 meters) for any changes. "A variety of indicators are backing this scenario. The thing we should try to predict is when. It's clear it's imminent." The geologist cautiously raised speculation that an eruption could take place in a couple of years. According to historical records, Baekdu was an active volcano. Major activity in the 1960s created a caldera on its peak, whose circumference is nearly 14 kilometers with an average depth of 213 meters and maximum of 384 meters. Volcanic ash from this eruption has been found as far away as the southern part of Hokkaido, Japan, according to records. Small-scale eruptions were recorded roughly on a centurial basis - in 1413, 1597, 1668 and 1702. The latest volcanic eruption recorded at the 2,744-meter mountain was back in 1903. The mountain has stayed inactive since then, leaving it categorized by scientists as dormant.

The Chinese government developed the mountain and surrounding areas as a tourist destination drawing tens of thousands of visitors from around the world each year - many of them from South Korea. Yet, "unusual signs," including minor trembling among others, began to emerge in June 2002 and a 7.3-magnitude earthquake rattled areas in the vicinity of Baekdu, according to geologists. The frequency of the quakes has notably increased since then. "It seems that a shockwave from the quake reactivated magma approximately 30 kilometers beneath the mountain," said Prof. Hong Tae-kyung at Yonsei University's department of earth system sciences in Seoul. "The more frequent these are, the higher the possibility of an eruption." According to a recent TV program based on interviews with officials at a Chinese institute monitoring volcanic activity at Baekdu, minor quakes which are too weak to be felt by human beings take place nearly 100 times per day. "We saw the number steeply increase in recent years," the program quoted an official as saying. The program showed crumbled stone steps leading toward the top of a scenic waterfall at the heart of the mountain, explaining they recently fell apart due to frequent trembling in the region. Among other indicators backing the scenario of a future eruption is the height of Baekdu, which has grown nearly 10 centimeters since 2002. Experts say bloated magma, a precondition of eruption, is gradually pushing up the height of the mountain as well as the temperature on the surface. On October 1, 2006, a Russian satellite found the surface temperature of the mountain notably higher than before. The finding came just days after North Korea conducted an underground nuclear bomb test in its northern region, indicating the test was a catalyst reactivating the magma, analysts said.

The increase in the number of withered evergreen trees on the mountain may be another indicator. "It was confirmed that pollutants from the surrounding areas are not to blame. If so, toxic gases spewing from the volcano could be a possible culprit," Yoon said. If the eruption is major in scale, it would bring about massive consequences to the two Koreas as well as the surrounding states, including China, Japan and Russia. "The amount of volcanic ash from the most violent eruption nearly 1,000 years ago was enough to cover the entire the Korean peninsula to a height of 1.2 meters," he said, citing scientific studies. "Baekdu's caldera contains nearly two billion tons of water. If it evaporates into the air all of a sudden mixed with volcanic ash of a major eruption, it would be blown to the east and consequently engulf Vladivostok in Russia and Hokkaido in northern Japan."

Baekdu Mountain is stratovolcano whose cone is truncated by a large caldera, about 5 km (3.1 miles) wide and 850 m (2,789 ft) deep, partially filled by the waters of Heaven Lake.

Hmmm.... is it normal that Katla is emitting that much smoke?

I hope it is...

not smoke or steam, just early morning clouds and fog..

believe me if Katla goes you will know immediately

Katla Volcano In Iceland Shows Signs Of Increased Activity

Fears are growing that the Katla volcano in Iceland could soon erupt after volcanic activity at the site increased by over 200% in recent days.

Seismic readings of the volcano indicate the tremors around the area have increased substantially.

Four earthquakes were detected near Katla during a 12-hour period on May 21st, more than at any other time since the Eyjafjallajokull volcanic eruptions first occurred in March.

Three earthquakes at the Katla Volcano were reported by the Disaster and Emergency website Hisz.rsoe.hu on Sunday evening. The tremors may have been due to ice movements within Mýrdalsjökull glacier or magma movement under the volcano.

The last earthquake to take place at the volcano was recorded this morning.

The eruption of the long-dormant Eyjafjallajökull volcano has prompted fears among some geophysicists that it might trigger an eruption at the larger and more dangerous Katla. In the past 1,000 years, all three known eruptions of Eyjafjallajökull have triggered subsequent Katla eruptions. The last large eruption at Katla was in 1918 but there have been small eruptions at Katla as recently as 1955.

An eruption of Katla volcano has the potential to be more devastating than the current eruption of Eyjafjallajokull. Geophysicists at Iceland’s Institute of Earth Sciences say Katla would be locally and globally damaging.

Icelandic President Ólafur Grímsson has warned Governments around Europe that a significant eruption at the volcano is ‘coming close’. He said: "We [Iceland] have prepared ... it is high time for European governments and airline authorities all over Europe and the world to start planning for the eventual Katla eruption".
