Lot of disturbance today. Wake Island looks almost the same patterns and to a lesser degree Tristan. Is there a big Pacific storm do you know?

Pitcairn, Antartica. as well

There have been a few rumblings as usual in the Kermandec region. Looks like instrumental gliches to me if it isn't related to the recent quakes. There was a 5.4 in Fiji. Have a look at surrounding sites and see if they have the wobbles or if it's isolated to that station.

This is from the 23/24. I looked at the the other Webicoder and saw nothing major on those,only this one was freaking out. Saw the Seismo on this Story .

Have seen similar anomolies on the PNSN webicorders and have been assured by those more experienced on ATS that they are only technical glitches.

I do agree with the article in that it is a very seismic area and alot is continually going on, but I wouldn't count on that site being very reputable. They had no experts claiming that was happening in the seismos, only commenting on the new fault in NZ. That whole area is volatile and I have no doubt that it's all connected - which is why I think the recent NZ quakes were aftershocks of the 2007 NZ earthquake, perhaps even making this 'new' fault active again.

It's probably an area which could be better monitored.

I've seen a few of your posts but I can't read them, can you PLEASE use paragraphs?! I'm not having a go, because I genuinely want to read what you're saying, but it's just too hard to focus. (am not on a desktop comp so I can't highlight as I go along, which is how I usually view blocks of text)

According to John Seach, the Santa Maria volcano in Guatamala has erupted. I'm fairly sure there was an earthquake in that area not so long ago.
From the web site

On 3rd March an explosion occurred from Caliente crater at Santa Maria volcano in Guatemala. Ash emissions reached 10,800 ft above sea level and produced ashfall in towns to the west and southwest of the volcano. The explosion generated a pyroclastic flow which moved 2.5 km down the southwest flank. Activity continued on 4th March with moderate explosions ejecting ash to a height of 11,000 ft above sea level, and ash fall on surrounding farms.

Meanwhile, according to Seach, Fuego is still actively erupting (also in Guatama)
and Kilauea volcano in Hawaii continues to erupt also.

Don't know about Fuego but the others are all on the always erupting list.

I think that might be in the lava tubes.

Quite a few right now, i.e. in the first 2 hours of today (UTC)

That makes 18 in the last hour and 8 minutes. Yup I think that is a swarm!

I came by to see what you had on Hawaii - quiet a swarm.
Have any harmonic tremors been detected - any ideas as
to what is going on? Thank for the image and list.

About the Puuoo volcano.

Hawaii volcano sudden change: Pu’u O’o collapse, new eruption site

HAWAI‘I ISLAND, Hawaii — At 1:42 p.m. HST this afternoon, USGS Hawaiian Volcano Observatory (HVO) monitoring network detected the onset of rapid deflation at Pu‘u ‘O‘o and increased tremor along Kilauea Volcano’s middle east rift zone. At 2:00 p.m., Kilauea’s summit also began to deflate.

Between 2:16 and 2:21 p.m., the floor of the Pu‘u ‘O‘o crater began to collapse, and within 10 minutes, incandescent ring fractures opened on the crater floor a few tens of meters away from the crater wall. As the floor continued to drop, lava appeared in the center of the crater floor, the northeast spatter cone within Pu‘u ‘O‘o collapsed, and an obvious scarp developed on the west side of the crater floor, with lava cascading over the scarp toward the center of the crater.

At 2:41 p.m., the scarp on the west side of the crater floor appeared to disintegrate, exposing incandescent rubble. Five minutes later, the collapse of a large block along the east crater wall produced a dust plume.

For those of you who didn't know what she looked like here is a before and after shot

Now that is very interesting. I thought the lava level was falling. I also have the before shots - but take look at my shot from last night which is the same camera angle (they have changed it since the 'before' shots). That is one heck of a drop!

This 02:45 UTC

I have been trying to find a seismo that is still on line with real-time data however within the past few months ALL the Hawaiian seismos are taken OFF the real-time data list.

If I was not a rational person I would shout conspiracy!!!

The most recent data available is only a few days before and including ordinal day 54 and we are now in ordinal day 65. It is as if the 11 days in between have simply been removed since normally there is between 14 and 18 days of data and now there is 5.

I will see if I can get anything on Vase but I doubt it.

I have found one. PAU. It is rubbish as it has been off line most of last night but does appear to be functional now.

PAU.HV..HHZ.2011.065

I will see if I can get anything from it.



I managed to get the last part from 09:39 approx. There is no HT audible but lots of quakes. This is the frequency analysis at 50x speed. The tall spikes are the quakes.

It is a very big drop, lovely shot. I wish I had kept monitoring it. I did until the end of January when It looked as if all activity had slowed. I had a crude system of watching the rise and fall but had nothing dramatic.

Alright folks... I'm posting this in a few different threads, as I believe it is relevant and important to share. So if you see it here, and then another, you were warned. LOL

It is published in the journal Nature dated 3 March 2011. A magma chamber is a large reservoir of molten rock (magma) located several kilometers beneath a volcano, which it feeds with magma. But what happens to the magma chamber when the volcano is not erupting? According to volcanologists, it cools down to an extremely viscous mush until fresh magma from deep inside Earth 'reawakens' it, in other words fluidizes it by heating it through thermal contact. The large size of magma chambers (ranging from a few tenths to a few hundred cubic kilometers) explains why, according to this theory, it takes several hundred or even thousand years for the heat to spread to the whole reservoir, awakening the volcano from its dormant state.

However, according to the mathematical model developed by Burgisser and his US colleague, reheating takes place in three stages. When fresh hot magma rises from below and arrives beneath the chamber, it melts the viscous magma at the base of the reservoir. This freshly molten magma therefore becomes less dense and starts to rise through the chamber, forcing the rest of the viscous mush to mix. It is this mixing process that enables the heat to spread through the chamber a hundred times faster than volcanologists had predicted. Depending on the size of the chamber and the viscosity of the magma it contains, a few months may be sufficient to rekindle its activity.
