I queried the VEI6 rating on Puhueye over at BT and this is what I got in reply. Looks like someone has been fecking with the Wikepedia article.

if nothing specific has changed the last hour, compared to the last few days, that is complete nonsense. In order to be classified as a VEI 6, an eruption needs a >25km plume and massive, massive amounts of ejecta. I can see where they have gotten this idea: someone with no idea of geology changed the wikipedia:

Nabro plume from space :

Magnitude 5.5 - ERITREA

This would be the largest quake since the day of the eruption, this could signal that another phase in the eruption may soon begin.

Nabro entering a more active phase again.

Notice the plume growing over the past hour or so :

(Edit : Looks to be weakening again already...)

trying to keep up with all these earthquakes and volcanos lately. LOL

RSOE is lit up today .

Saw there was a 4.9 off coast of US as well.

Ilvar Khorstoon over on the Eruptions blog belives that the Nabro eruption has the potential to become another Krakatoa.

Very frustrating that there is no real monitoring going on there. There hasn't even been any images from aircraft since the eruption began.

Hi all,

Have been looking into earthquake reports for 2011 to date, 19 June.

It looks like 2011 will be a record breaking year, especially for moderate earthquakes.

A lot of people have been talking about whether we are experiencing more earthquakes than usual this year. The answer is yes for earthquakes in the range 5-7.

Here is an article on IWO.

Dead Fish on a Bali Mountaintop
Massive Fish Die Off Reported as Volcanic Lake at Bali’s Lake Batur Suddenly Changes Color.


(6/19/2011) A unusual natural phenomenon is causing concern for communities living around the edge of Bali’s Lake Batur at Kintamani.

On Sunday, June 19, 2011, the waters of the lake that sits in a volcanioc crater suddenly changed colors to a whitish-blue shade followed by the sudden death of thousands of fish (tilapia) living in the lake.

According to NusaBali, villagers for the lakeside community of Lintang Danu recount that the lake suddenly changed color on Sunday (June 19) morning in the areas surrounding the villages of Songan. Batur, Kedisan and Buahan. Shortly after the color change, thousands of freshwater fish floated to the surface and begin washing up on the lake’s shore. Fish farmed by villages in the shallows of the lake also died with the changing color of the lake.

Local fisherman, who traditionally plant local freshwater majiar fish (tilapia) in the lake, scrambled to the location to rescue fish in distress but still alive to place them in fresh water pools ashore.

The head of the Wildlife and Fisheries Service for the regency of Bangli, A.A. Ngurah Shamba, said his office was still surveying the situation and trying to understand the natural phenomenon that change the water color and caused the fish die-off. Samples of dead fish have been collected for laboratory analysis.

Local villagers are blaming the situation on an underwater explosion of the volcano concealed by the crater lake. A village chief from the local community of Buahan, I Made Antara, was less certain on the cause of the phenomenon, saying the die-off might be due to a an underwater explosion, a fluctuation in water temperature, a current of acidic water or an unusual particle introduced naturally to the water.

Another villager form Songan, also on the lake’s edge, said this is not the first time such an occurrence has taken place. Jro Saba said a similar phenomenon occurred about 3 years ago, but at that time the change in water color was less pronounced that is now the case. Said Saba: “I suspect that there was an explosion in the center of the lake that released sulphur that killed the fish.” He estimates the losses suffered by local fish farmers is in the billions of rupiah.

Saba said the change in the lake’s water might also have a deleterious effect on farmers living near the lake. Farmers who use the lakes water for irrigating their crops of shallots, onions, cabbage and other crops are now concerned the colored water may be harmful to their crops.

The chief of the Disaster Alleviation Office for Bali, Putu Anom Agustina, has issued a statement declaring that the change in water color was not tied to volcanic activity. Said Agustina: “this is a natural phenomenon, not due to the volcanic activity of Mount Batur. It is perhaps due to strong winds that blew sulfuric soil into Lake Batur.”

Agustina said the volcanic status of the lake remains unchanged, at a normal “level I” rating.

Mount Batur has exploded 26 times since 1804, with the last cataclysmic explosion happening 2,000 years ago. In recent times, the largest explosion occurred on August 2, 1926. That explosion deposited large amounts of lava into the lake from Mount Batur.

Mount Batur is located to the west of Bali's sacred Mount Agung, which suffered a major explosion in 1963 claiming between 1,500 and 2,000 lives.

When I see the dead fish reports I go 'oh oh' ...

Update on Nabro

UPDATE 19/06 – 21:36 UTC : According to NASA, the volcano spewed ash and large amounts of sulfur dioxide gas—the highest levels ever detected from space, according to preliminary estimates from researchers at NASA’s Goddard Space Flight Center.

Found this image in the comments on the Eruptions blog :

Big one in Chile earlier too.

Chilean Seismological Survey measured quake at 6.4 on Richter scale, about 125 kilometers depth. Struck 73 kilometers NE of Calama.

Chilean Interior Ministry: No immediate reports of damage, casualties following earthquake


USGS had it at 6.1 then upgraded,thats unusual for them to upgrade.

Someone on the Eruptions blog thought it was unusual that there has been no aftershocks at all recorded from quite a big quake. You'd expect aftershocks from a tectonic related quake of that size.

The epicenter of the quake was 15km from San Pedro volcano.

yeah, strange all right isnt it?

Just looked on RSOE saw thats theres about 15 volcanoes fairly close to it. :eek:

Just saw this from the BBC. 8 villages in Ethiopia are covered in volcanic ash.

4.33 Greenland. When you look on the map its almost directly across from Ireland.

close!!! is that a normal place for earthquakes?

Greenland is, not sure about that spot though. Its directly across from us almost
Strongest one recorded was in 2009, 6.1, according to link below.

It's right on the mid-Atlantic ridge.

There have been quite a few quakes on the ridge over the past few months.
Anyone know where to find information on past quakes on the mid-atlantic ridge, particularly for the north atlantic. Would be interesting to see what magnitude the largest quake recorded was.

Good article here on Tsunamis in the Atlantic Ocean from quakes on the mid-Atlantic Ridge.

new Zealand getting lot of action today. read on a site they have had 7500 quakes since sept2010.

Finally, the first video with footage from the Nabro eruption.

Bugger bugger, the video was removed before I got a chance to view it. :(

Wonder why it was removed??
