Last update: April 11, 2014 at 8:41 pm by By

After Rodger Wilson was obliged to discontinue his daily participation at this site, we have decided to start up an El Hierro type article. The newest additions will always be on top and if the article gets too long, we will cut off a part of it and archive it. This url will always be the one to follow and if you leave our page open in your browser, the page will refresh every 60 minutes automatically.
Please be a little patient with this new format.
This report is compiled out of many information sources.

Mount Kelud (Java, Indonesia) makes thousands of  people to evacuate (February 14)
Mount Kelud erupted yesterday evening. Due to the cloud cover, no footage of the eruption itself is available but the result of the eruption can be clearly seen on the video below. The eruption sent volcanic ash covering an area 500 kilometres (310 mi) in diameter. The rain of ash covered a third of Java island from Malang to Yogyakarta in Central Java.
Mount Kelud is located in East Java, has a height of 1,730 meters, and erupted on Thursday (13/2) at 22:50 local time  (UTC+7). The impact of the eruption was not only visible in nearby Kediri and Blitar,  but also in other areas such as Kebumen, Sidoarjo, Surabaya, Mojokerto, Madiun, Yogyakarta, Sukoharjo, and Kudat.
3 airports (Juanda Surabaya, Adisumarno Solo and Yogyakarta Adisucipto) are closed due to the danger of ash in the engines. Volcanic ash in the airplane engines can cause engine failure and crashes)
Health experts are requesting the population residing around Mount Kelud to be aware of exposure to volcanic ash. Volcanic ash is very dangerous if inhaled by human beings and can cause also skin irritation. Additionally, inflammation of the eyes is also a possibility.

Rodger Wilson reports (February 13)

Seismicity continues at Mammoth Mountain volcano (CA) (staion MMP).  Whereas yesterday’s activity was characterized by higher magnitude events between M1.0 and M2.3 and a few short pulses of spasmodic tremor, today’s activity appears to be the opposite with numerous smaller magnitude events and more frequent periods of tremor.  I have included the most recent plots of deformation occurring in-tandem with the seismicity.  Both the tilt and dilatometer data show another episode of movement occurring on or around 10 February.  I have to be careful in attributing all the movement to volcanic processes as the region is also receiving heavy snow at this time!  The instruments were installed deep underground to prevent surface activity such as snowfall affecting readings,..but it still can!
Several Nicaraguan volcanoes are giving “primers” on long-period (volcanic) seismicity today, including:  San Cristobal (station CRIN), Masaya (station MASN), and Concepcion (station CONN). Note the emergent (gradual) onsets of the events, their generally low amplitudes and long duration vs. amplitude, as well as their low frequency content as denoted by alot of “open space” between peaks and valleys of their waveforms. Volcano-tectonic, or just plain tectonic earthquakes usually have sharp, impulsive onsets with high frequency content (dark traces due to sharp, tightly spaced peaks and valleys), and relatively short durations versus their amplitudes (if they are local events!).
A small eruption occurred yesterday (video included) at Chaparrastique (San Miguel) volcano (El Salvador) (station VSM), following days of slowly increasing tremor.  Since the event, tremor has eased slightly at the volcano, but will likely rebuild over the next few days.
  Activity is slowly waning at Tungurahua volcano (Ecuador) (station RETU).
Nishinoshima volcano island, Japan (January 7)
The video below is from yesterday’s TV Asahi news, Asahi published a video from the Japanese coast guard, taken on February 11th at around 2pm. The island is still growing. There is red lava in 2 craters. And the lava stream to the east, that stopped in december, is flowing again.The coast guard released another warning for ships and planes in the area not to come too close. It is still dangerous.

Rodger Wilson reports (February 12)

Small earthquakes (magnitudes generally < M2.0) continue unabated at Mammoth Mountain volcano (CA) (station MMP).  There have been fewer and shorter duration pulses of spasmodic tremor during the past 24 hours.  I have included a graphic showing the relationship between spasmodic tremor and deformation observed at the volcano during previous episodes of unrest.
There have been periodic very low frequency (<1 Hz) visible on spectrograms during this sequence that may represent episodes of deformation.

Also,…another pulse of seismicity at Yellowstone overnight (station YNR).

Neither of these sequences indicate forthcoming eruptive activity, but the activity at Mammoth is clearly volcanic in nature and scientifically interesting to watch.  It is also the highest level of shallow seismicity to occur at the volcano since the late 1990′s.


 

Rodger Wilson reports (February 11)
Spasmodic tremor (fluid movement) has become more frequent during the past 24 hours at Mammoth Mountain volcano (CA) (station MMP).  Dilatometers also show changes associated with the activity during the same period.  Several pulse-like periods of extension across the volcano have occurred since the first of the month, associated with increases in seismic activity.  Also very shallow earthquakes have appeared immediately west of the edifice overnight.

Another United States caldera (Yellowstone) is showing some signs of life over the past few days (station NRP).  Careful all you eruption baiters!!!  This activity is far from pre-eruptive levels!!!

Tremor at Chaparrastique (San Miguel) volcano (El Salvador) (station VSM) has continued to climb, periodically saturating (overloading) local seismometers overnight.

Eruptive activity at Tungurahua volcano (Ecuador) (station RETU) has de-volved into numerous discrete explosions now.


 

Rodger Wilson reports (February 10)
An earthquake swarm continues beneath Mammoth Mountain (CA) (station MRD) albeit at a reduced rate (still some short pulses of spasmodic tremor though).
SNET continues to observe rising seismic energy emanating from Chaparrastique (San Miguel) volcano (El Salvador) (station VSM). An earthquake swarm occurred amidst the continuous tremor resonating from the volcano beneath its North flank yesterday.
Explosive outbursts (including pyroclastic flows) continue at a slightly reduced rate at Tungurahua volcano (Ecuador) (station RETU).
Volcanic seismicity remains elevated at Ubinas volcano (Peru) as well.


 

Rodger Wilson reports (February 8)
Two relatively strong pulses of spasmodic tremor (fluid movement) occurred at Mammoth Mountain volcano (CA) (station MRD) early today.  Seismic events appear to have further shallowed, to around 3 km now, versus the 5 km of previous days.  Compared with the deformation recorded during the deep earthquake swarm at the volcano in October 2012, the current shallow activity is only producing weak uplift and extension.  I also note a 1 Hz “noise” developing on spectrograms during the swarm activity over the past two days.  Not sure what to make of it, but it’s real.

Rodger Wilson reports (February 7)

There’s a shallow (~5km depth) earthquake swarm underway at Mammoth Mountain volcano, California (station MRD) (Do you think this might herald the arrival to near the surface of fluids involved with the October 2012 deep swarm beneath Mammoth?).

Eruptive activity is again intensifying at Tungurahua volcano (Ecuador) (station RETU) according to current spectrograms there (read from bottom to top).

Internal tremor is also (slowly) intensifying at Chapparastique (San Miguel) volcano (El Salvador) (station VSM).

Ubinas volcano (Peru) has also experienced numerous volcanic earthquakes which have now evolved into extended pulses of volcanic tremor at the volcano.


 

Tungurahua pyroclastic flow video (February 4)
The video below shows very well how a pyroclastic hot cloud descends from the volcano slopes and continues further and further. At the end the cloud arrived closer and closer to the video recording people


 

Tungurahua Update (February 2 @ 09:20 UTC)
- The Ecuadorian Civil Defense authority has called the Orange alert for a limited number of villages on the slopes of the volcano. Hundreds of people living in these villages have received the order to evacuate. Especially the extremely hot pyroclastic flows are a big risk for these communities.
The city of Banos, at the foot of the big volcano, has received instructions to prepare for a possible evacuation if the current situation would deteriorate.
A number of nice images from the eruptive activity can be found here


 

Big eruption on Tungurahua volcano, Ecuador (February 1 @ 23:12 UTC)
This is the webcam image we have copied a few moments ago . the image dates from less than an hour ago !
The volcano reactivated last Thursday. Today continues emission of ash is taking place. The ash is luckily carried away in the direction of the Oriente (lowlands to the east). The eruption can be seen from far away (ie Riobamba)

Returned villagers have to flee again on Sinabung volcano, 14 people killed (February 1)
An Indonesian volcano erupted on the island of Sumatra, leaving at least 14 people dead. Torrents of lava and pyroclastic flows gave neighboring villages an almost apocalyptic look.
2,460-meter-high Mount Sinabung erupted three times on Saturday, producing columns of ash about 2 kilometers tall and spreading hot rocks and ash over a 4.5 kilometer radius, said Sutopo Purwo Nugroho, spokesman for National Agency For Disaster Management (BNPB).
The RT report is very well written en has a lot of images showing what happened earlier today

    Hopefully White Island actually erupts this time!
    NZ volcanoes have been really pathetic lately. lots of minor activity that never ends up going anywhere.

  2. Biard cédric says:

    It is false. Video sakurajima published in February on YouTube!!!

    Click below is entitled to the video on “YOUTUBE”.

    Video published in February one YouTube!!!

    • Armand Vervaeck says:

      We know, we did not mention that it was from today but we will clarify

    • Why say that there is activity if there is not?? I look at the Japanese official site and there is nothing! The 09 and 10 yes but not 11, I’m sorry …

    • Armand Vervaeck says:

      Once again – The daily activity overview is another article. We have now added (OLDER) Richard Roscoe video’s. Sorry for the confusion.

    • OK thank you if you want one more information, I look at 200 real time webcam and I publish on my page Facebook at most within the hour, I do not see everything and I do not know everything especially when I sleep but it will bring you maybe one more from time to time.

    Those photos of Sakurajima are stunningly beautiful.

    • Armand Vervaeck says:

      We love them too, the nature can be extremely beautiful but you do not want to be in that cloud

  4. goldminor says:

    It’s really great to see the page back up. Congratulations.

  5. Stephen Desrosiers says:

    I love this page. It’s good to have a daily dose of my volcano fix! Keep up the good work!
