The latest round-up of volcano news, including the potential spotting of a dome growing at Sarychev Peak, rumblings in El Salvador and small ash plumes at Anak Krakatau.
Its not every day that a new geyser appears out of the blue, but that is exactly what appears to have happens in Kamchatka, as the Prikolny (“Peculiar”) Geyser has appears near Uzon caldera.
Two volcanoes headed in opposite directions: the Alert level was raised at Mayon in the Philippines, while 24/7 staffing of the AVO operations center has ceased now that Redoubt seems to have quieted down.
Water and volcanism! Read what I have to say about this and other matters in my interview in ‘The Reef Tank’.
If the activity at Mayon continues to increase, over 75,000 people could be evacuated from the region near the volcano. As usual, there are also those who don’t want to believe the volcano is a threat.
Every once in a while, the Astronomy Picture of the Day throws in a volcano with all the space imagery. July 13’s image was one of the best. Plus, oil production will resume next month in the Cook Inlet, Alaska.
The weekly USGS/SI volcano report is out, with some eyewitness description of the recent eruption in Ethiopia, Shishaldin in the Aleutians going on Yellow Alert and two volcanoes in Guatemala making noise.
The thermal anomaly at the crater on Shishaldin in Alaska appears to be increasing in intensity and now there appears to be some indications that seismicity is following suit. Is something up?
A look at “folk volcano monitoring” in the Philippines, Kilauea takes out another piece of the doomed Royal Gardens subdivision and another great images of an active volcano from NASA.

Did an Eruptions reader find a volcanic eruption before anyone else? Maybe so for the new eruption going on at Manda Hararo in Ethiopia.
The glow at Halema’uma’u Crater on Kilauea’s summit has been blocked by a rockfall that has clogged the vent with debris. Now, the question is what caused the rockfall and what effect it might have activity at the summit of the volcano.
The alert level hasn’t been changed, but increasing signs of activity at Mayon in the Philippines is cause for concern.
More activity in Ecuador and Indonesia. Also, check out how a major airline deals with volcanic eruptions.
Five hundred meter lava fountains in Ecuador, webcams for all (well, some) in Kamchatka and the rise/fall of lava at Kilauea, all in this week’s USGS/SI weekly report.
Icy volcanoes on other planets are kind of salty, too. That along with a 3-D image of the Sarychev Peak eruption and another eruption in Alaska.
I tackle questions from you, the Eruptions audience. In this mailbag: what makes Chaiten so special, what is the volcanic legacy of the Appalachians and where did all this magma come from anyway?
What happens when you drill into an active magma body? Well, not as much as you think, but it is still awesome, nevertheless (especially when your officemate does it).
The ongoing growth of the dome(s) at Shiveluch are continuing to produce some impressive ash columns.
They’re not calling it the end, but the activity at Redoubt seems to be waning significantly over the last month.

Sarychev Peak is now the number “sulfur dioxide” event of 2009, with a plume reaching out eastward over the Pacific. Meanwhile, the ash is causing many an unhappy air traveler over the last few days.
The eruption appears to be waning and NASA has released possibly the most stunning volcano image I’ve seen in years.
