Philippines Mt. Kanlaon volcano summit closed after large cracks found near crater
Posted on February 10, 2012 by The Extinction Protocol
February 10, 2012 – BACOLOD CITY, Philippines – Mount Kanlaon, an active volcano, has been declared temporarily closed to mountaineers after large cracks believed to have been caused by Monday’s 6.9-magnitude earthquake were observed at its crater and land surfaces, a local official said Friday. Kanlaon straddles the provinces of Negros Occidental and Negros Oriental. It has an elevation of 2,435 meters (7,989 feet) and a base diameter of 30 kilometers. Cecil Cañada, Mt. Kanlaon Natural Park (MKNP) superintendent, said at least three 50-meter long cracks have been noted near the crater, while other cracks and a landslide have been noted within the MKNP. A landslide was also seen at the Margaha Valley, the old crater of the volcano, he added. An assessment was conducted by accredited trained guides and members of the rescue group based in Guintubdan, La Carlota City, in coordination with the MKNP Eco-tourism Officer and Biologist Angelo Bibar, Cañada said. Their report revealed that some portions of the volcano’s crater were affected, and land surfaces had cracks and evidences of landslides, he said. Cañada also maintained that the aftershocks from Monday’s earthquake and occasional heavy rainfall could pose danger to the life of mountain trekkers and tourists in the park. The Philippine Institute of Volcanology and Seismology has been informed of the quake damage to the volcano and they were trying to arrange for an aerial survey of the area, he added. However, it is difficult to get a helicopter as they are being used for relief operations in Negros Oriental, Cañada said. The volcano continues to be under observation amid the continuing aftershocks, he said. The Mt. Kanlaon volcano is part of the Negros volcanic belt and last erupted in 2006. –Inquirer

Indonesia’s Mt. Lokon volcano unleashes 2 km high ash cloud
Posted on February 10, 2012 by The Extinction Protocol
February 10, 2012 – INDONESIA – A restless volcano in northern Indonesia erupted Friday, spewing clouds of ash as high as 2 kilometers into the sky, the country’s National Disaster Management Agency said. The authorities are warning residents to stay away from the volcano, Mt. Lokon, in North Sulawesi, said Sutopo Purwo Nugroho, a spokesman for the disaster management agency. A 2.5 kilometer exclusion zone had already been set up around Mt. Lokon, which had been showing signs of activity in recent days. A series of eruptions by Mt. Lokon in July prompted the evacuation of thousands of local residents. The volcano also erupted in October and December. Indonesia is located on the “Ring of Fire,” an arc of fault lines circling the Pacific Basin that is prone to frequent earthquakes and volcanic eruptions. -CNN

Alert Level of Galunggung has been raised

Alert status raised on Indonesia’s Galunggung volcano

The alert status of Galunggung volcano in West Java, Indonesia, was raised today due to an increase of its water temperature and a change in color. Discoloration of the Crater Lake had started to be noticed in September 2011, but the changes have increased recently. According to the local volcanologists monitoring the volcano, the whole lake is now of muddy khaki color....

In the past 24 hours — FOUR SEPARATE DORMANT VOLCANIC SITES in the Southwest USA have shown activity!

Starting in southwest Utah– 2/12/2012 (yesterday) — a swarm of earthquakes near the Markagunt Volcanic Plateau.

Here is the link to my full post plus video from earlier:

[link to sincedutch.wordpress.com]

[link to www.youtube.com]

I think it all connected with trigger influence of some long-period seismic waves which extends across the extensive region including Utah, Oregon (see today quake) , North of California, ...

The example of this waves is resulted here
Thread: Strange vibrations or waves at Mary Lake Yell

They are registered there from the end of January - the beginnings of February (and today too are visible
[link to www.isthisthingon.org] thus if at first their period was 3-4 minutes then began to increase: at first till 5-6 minutes, now till 15 minutes .
If to assume that vibrations on seismograms are reaction of a stream of magma to waves, from the rough formula for vibrating waves
v=2*f*A (velocity, frecuency and amplitude)
and observing some increase in amplitude of vibrations at more or less identical frequency, it is possible to assume also increase in speed of a stream.
By the way, according to GPS the maximum speed just corresponds to station Mary Lake position

Nine weak ash eruptions reported at Guatemala’s Fuego volcano
Posted on February 14, 2012 by The Extinction Protocol
February 14, 2012 – GUATEMALA – Weak ash explosions continue at Fuego volcano. INSIVUMEH reported for 13 February that 9 eruptions were counted; producing plumes up to 500 m high and occasional rumbling noises. A steam plume is rising constantly about 100 m from the crater. The ash drifted 8 miles WSW. The new lava flow on the southwest flank in the direction of the Taniluya ravine is still active and about 200 m long. Blocks that detach from its front form small block avalanches that reach the vegetation. –Volcano Discovery

When the vents at Bob is finally clogged up and there is systemic pressure buildup, and it seems we are a minimum of weeks away from that happening.

[link to volcanocafe.wordpress.com]

Results of the new Bathymetry

Bob itself has only grown with about ten meters since the last bathymetry. The depth from the surface to the top of Bob is 120 meters; it now has a base (foundation) of 350 meters. The reason for the limited growth is of course that Bob has grown a 75 meter high parasitic cone.

The effect of this is that Bob has by now clogged up and will most likely not be active any longer. Instead the parasitic side cone has taken over as the main vent, and will given enough time devour the old Bob.

During the last bathymetry the total ejected volume was 0.14 cubic kilometer. Today it is around 2 cubic kilometer of lava that has been ejected. That is an impressive number for such an unassuming little volcano. If it continues at the same pace for another couple of weeks it will surpass the total ejected volume of Eyjafjallajökull (2010) and Grimsvötn (2011), and those two are volcanic brutes compared to El Hierro.

GPS

Data from GPS:s are hard to get, and even harder to interpret since IGN for reasons unknown only give out summed up displacement figures, and that is not the up or down values that makes a volcanologist happy.

Regardless of IGNs oddities we know that the GPS values have been steady during the entire eruption. And that means that the amount ejected is the same as magma arriving into the system.

The other data, from the University of Nagoya, has been forbidden to be used by INVOLCANs so called director, aptly named Nemesio. But I do not really care about him, those GPSs also show stable values.
Gas values have been rather constant; yes they have gone up and down, but not in any spectacular fashion really. There is though one measurement value that would be very good to have, and I hope they are taking, and that is gas values inside the cave systems on the island. I will get back to this.

Earthquakes

Earthquakes are now far in between, very low in amplitude (strength), and actually point to an equilibrium state in the internal pressure. So, as long as Bob putters on, not much will happen regarding the earthquakes. One should also note that the earthquake are fairly stable in depth, and stay well within the boundary of the original earthquake wad.


Image by IGN. Showing all quakes from onset of activities. Todays quakes are well withing the boundary of this earthquake wad.
I would here like to seriously warn against falling into the almost hysteria that has been the last few days regarding the earthquakes. I can understand that the Hierreños got scared and felt betrayed when they saw equipment and aid personnel leave the island, and that is making them more afraid of the normal earthquakes. But it does not help if we give fuel to their fears. The earthquakes are of no importance at the current state.

Before worrying look at the earthquake wad above, and also at the scale-plot down below. Remember that the volcano could take heavy 4M earthquakes without breaking apart. Look very closely at the lack of motion on the plot below that shows that the energy levels have been minute for a long time.


Image by IGN. Look at how little energy has been released since 2012-11-21 compared to before.
Tremor

What we are seeing in the tremor is rather impossible really and makes Bob a rather intriguing event. We should have seen high tremoring as we did before. Why? Well, Bob is still ejecting as much as before and thusly we should see no shift in tremor. Instead we now have ultra low values of tremor.

What I think has happened with the tremor is due to several factors. First of all I think that the new vent of Bob is wider, I also think that the eruption has smoothened out the walls of the conduit giving a clear and nice ride for the magma to the surface. I also think that the composition of the magma has changed, more about that below.

Regardless, I was fooled by the drop in tremor, and so was almost everyone else. I at least admit to having been fooled by it.

What one should look at is the 0.59Hz tremor given by EOSO and EGOM stations. That is probably the tremor from the deep feeding tube. It might even be from the mantle plume.

Magma

In the beginning we saw pretty much reactivated old evolved magmas and semi solid rocks being erupted, after that followed a long phase of what probably was reactivated rhyolitic mush. That would explain all the ash in the water (suspended tephra) that we saw back then. Now all of that is probably cleared away and we have an unevolved stream of basalts comparatively low on gasses being ejected. This basalt is of deep origin as evidenced by the UrTh (Uranium/Thorium) content in the samples that has been collected from the surface.
Given what we now know there is no reason for Bob to shut down for at least the next couple of weeks. As long as tremor levels are low, there is no rapid increase in earthquake rate and amplitude, and the 0.59Hz is going, then it should just be ticking away. I would not even rule out that Bob pops up from the surface in about a year.

What could happen in a couple of weeks is that Bobs new vent clogs up. And it is then it could get interesting. Most likely a new vent would open up close to Bob again, but that is not sure. If a new vent does not open up the Volcano no longer has an open pressure relief valve. And then systemic pressure will start to rise. In that case we will see earthquake rate and amplitude start to rise. And sooner or later the magma would go somewhere. The most likely thing is still not an eruption of Tanganasoga central volcano.

The most likely thing to happen is that a vent opens up somewhere upstream of Bob’s feeder tube from the magma chamber(s). The other likely thing is that the magma will find a new easy route out and that would be one of the old lava tubes that already exist all over the island, namely the cave systems. And that is why they should really have gas measurements taken inside of the caves.

Right now there is no apparent danger of the eruption changing into something more dangerous. As long as Bob is puttering away, there is just not enough pressure for anything else happening.

Thanks Luisport for very interesting report and conclutions of CARL !
But.
It semms to me that he not quite considers one essential detail in the reasonings: magma outpouring has begun and proceeds on depth more than 350 meters and to stream to it it is necessary to overcome pressure more than 35 atmospheres (10 meters ãëóáèíû=1 atmosphere). It means that pressure created to it equally or is more 35 kg on square centimeter, that is equally or it is more than 350 tons on square meter (35 * 100 * 100 / 1000). Since the eruption beginning has passed more than 4 months, and all this time it with such pressure not only streamed, but also pressed on surrounding breeds and including moving ahead under a land in direction Tanganasoga (the certificate to that epicenters of earthquakes are). Filling all emptiness and breaking all "weak" partitions. As it is far on a land and upwards it has promoted, certainly we precisely don't know, however it is obvious that has promoted essentially. And where now "the weakest" place in which pressure - near to already available Bob or on a land, including in Tanganasoga can be dumped, isn't known.

You should tell them and post in his blog...

earthquake-report.

At least some assurance that CAP will be on higher alert now.

Update 15/02 – 19:11 UTC
– 3 more earthquakes : we will from now on only change the number in the title.
Nobody knows what will happen next but CAP science center in La Restinga and IGN Madrid, who is following up the instruments via data link, will certainly be on a higher alert than normal.

Update 15/02 – 17:52 UTC
– 4 more earthquakes ! , which brings the total of listed earthquakes to 20 today, the most since many months !
– we have still a minimum HT signal which means that the eruption is still hoing
– NO jacuzzi or even stirring area anymore.
