Volcano watch 2006

Mt. Colima shot a column of ash 1 mile high today.

Western Mexico's Volcano of Fire sent a towering column of ash and gas more than a mile into the air Thursday, authorities said.

Winds blew a 7,150-foot column of ash toward the west. No communities were affected, said authorities in Jalisco state.

The dome at Montserrat Volcano partially collapsed today, sending clouds of ash over the sea.

"Today's collapse is the result of a high amount of seismic activity at the volcano," Loughlin said.

The partial-dome collapse, which started at about 1 p.m. local time (1800 GMT) and lasted for 20 minutes, followed two earthquake swarms in recent days in which the observatory's seismic network recorded 1,236 small earthquakes at the Soufriere Hills volcano during a roughly weeklong reporting period, she said.

Fast-moving bursts of hot gases and rock fragments shot down the eastern flank of the volcano into the Caribbean during the collapse. Nearly all the gray plumes of ash spread over the sea with a small amount coating inhabitable areas, Loughlin said.

Magnitude is an estimate of the energy release or size of an earthquake. Magnitude estimates are calculated from the amplitude of wave energy on a seismograph adjusting for the distance of the seismograph station from the earthquake (seismic waves spread out and are absorbed during propagation and thus generally become smaller at greater distances from the earthquake epicenter) and the amplification of the signal by the seismograph.

Again this is what I find so very odd. For all of the seismic activities on the Aleutean Island. The “further” we go away from the epicenters the “greater” the amplitude of the wave energies become. So instead of the wave energies being absorbed during propagation, every time I post these seismograms for quakes, they become greater the further away we go from the epicenters.

One thing odd yet again is that this is only true as I check seismographs to the West of these epicenters. Never East. Propagation does appear the further East of the epicenters I go on these island seismograms.

This can easily be confirmed by going to the very top link for the AVO. Here is yet another set of seismograms that show what I mean. It goes against everything that the website “Explorations in Earth Science” suggests as the rule.

We can't forget the world's most famous volcano... Yellowstone

June 2006 Yellowstone Seismicity and Deformation Summary

Seismicity Summary:

During the month of June 2006, 196 earthquakes were located in the Yellowstone region. The largest of these shocks was a magnitude 2.4 on June 13, 2006 at 2:05 AM MDT, located about 5 miles south southwest of Madison Junction, Wyoming. No earthquakes in this period were reportedly felt. Over half of the earthquakes were related to two small swarms in the northwest part of the caldera and further northwest near Hebgen Lake.

Earthquake activity in the Yellowstone region is at background levels.

Ground Deformation Summary: Through June 2006, continuous GPS data show that most of the Yellowstone caldera continued moving upward at the same relative rates as the past year. The maximum measured ground uplift over the past 22 months is ~11 cm at the White Lake GPS stations. An example can be found at: www.mines.utah.edu...

The general uplift of the Yellowstone caldera is scientifically interesting and will continue to be monitored closely by YVO staff.

An article on another recent uplift episode at Yellowstone and discussion of long-term ground deformation at Yellowstone and elsewhere can be found at: volcanoes.usgs.gov...

This is the official bulletin from the Yellowstone Volcano Observatory
Source URL: volcanoes.usgs.gov...

The uplift is plugging along nicely and strange things are happening at the park. At what point to we start to ask more questions? Not to say there is a conspiracy or anything to keep information a little more difficult to find but I used to be able to find that bulletin by going to Google and typing "yellowstone earthquake activity" and getting the result to be like one of the first few entries on the first page. I went through five pages and couldn't find it. Fortunately I knew where to look for this information.

Colombian volcano spews ash, people evacuated

BOGOTA, Colombia, July 12 (Reuters) - The Galeras volcano in southwest Colombia shot rocks, gas and ash in a Wednesday eruption that prompted the government to evacuate about 10,000 nearby residents.

Television images showed thick clouds of ash hanging over the town of Pasto in Narino province. No injuries were immediately reported.

"The negative health effects could be serious and this could be only the beginning of a series of eruptions," government disaster response coordinator Eduardo Gonzalez told reporters.

btw thank you to all the members who keep these updates going. Indy for the Yellowstone info

Yet another one in the "ring of fire" stirring.

MANILA, Philippines - The Mayon volcano erupted Friday, a day after ejecting ash amid swarms of earthquakes, the Philippines‘ chief volcanologist said.

"A hazardous eruption is possible. We don‘t know when, maybe within weeks," Solidum said.

The government maintains a 3 3/4-mile "permanent danger zone" around the volcano‘s crater, but many residents still live or farm on its slopes. There was no immediate word on evacuations.

If you want a detailed earthquake map of yellowstone, this is the best I can find. It even includes an outline of the most recent Caldera:

looks like this one in Ecuador is kicking up a fuss

PINGUE, Ecuador, July 15 (Reuters) - The Tungurahua volcano spewed ash, gas and melted rocks for the second day straight on Saturday, sending hundreds of Ecuadorean villagers crowding into schools and churches seeking refuge.

I can't imagine living with something like that in my back yard.

With another 7.2 magnitude earthquake near the super-volcano Toba, on the Sumatra Island, will it increase his activity? Any signs of a wake up from the super-volcano?

Mt. Etna is starting to erupt again. Last major activity was in 2002.

Mount Etna, the largest active volcano in Europe, threw fire and rocks more than 800ft into the air yesterday.

The explosions are coming from two holes near to the top of the volcano, creating a lava field more than a mile long which is flowing at a rate faster than 90 cubic feet a minute. Even though the eruption has continued for three days, scientists said it had lost little of its force.

It perhaps would do, if its magma chamber was close to full when it was about to go, but last time was 75,000 years ago. Yellowstone has had eruptions of similar size and it takes 600,000 years before it goes again, on average.

Of course a smaller eruption of perhaps VEI 5 or so could happen, but not a VEI 8, ie a super eruption.

This is the second eruption since July 17. About 4000 villagers are now evacuated.

MANADO, Indonesia (AP) - Thousands of villagers were evacuated after a volcano on an island in eastern Indonesia started spewing lava and hot clouds, officials said Friday. There were no reports of casualties.

Nearly 4,000 people were evacuated from five villages, said Iskandar Gobel, a North Sulawesi provincial official, and police in the area said more would likely leave in coming days.

The status of the 1,784-metre Mount Karangetang, one of the country's most active mountains, was raised to the highest level more than one week ago, said Saut Simatupang, chief researcher at the government's volcanological agency.

this is interesting and a little scary too

New Volcano Type Found in Pacific?

A new type of volcano may be heating up the floor of the western Pacific Ocean.

Scientists suspect the new volcanoes occur at a crack in tectonic plates caused by stress as the plates slide past each other.

The group of small volcanoes, called petit spot volcanoes, was discovered far from the tectonic-plate boundaries (such as mid-oceanic ridges) that often spawn volcanoes, earthquakes, and other geologic activity

20,000 people have been evacuated from the areas surrounding Mayon Volcano in the Philippines fears of a major eruption in days or hours has been raised as Government moves quicky to move people away from the Active volcano after a series of major Ash Explosions Monday Morning in Manila.

According to the PHIVOLCS

Seismic activity and gas output at Mayon (13.2576°N, 123.6856°E) over the past 24-hours declined anomalously. The number of volcanic quakes decreased from the previous 109 to only 21 events since six (6) o’clock yesterday morning. The Sulfur Dioxide (SO2) emission rate also decreased from a high of 12,745 tonnes per day (t/d) measured on 07 August to 7,829 t/d yesterday. These changes or large swings in activity, along with the recent explosions, are indicators of the variability of the conditions of the magma system inside the volcano, and also reflect the high prevailing unrest.

Seems it is going to erupt soon.

With the full moon tonight, it will erupt tonight.

Hope we have greats pictures.
