23 Jul 08 – “Note that not only is
the caldera double the size of the one erupting in Chili,” says reader
Charles P., “but that a sister volcano, outside the caldera, began
erupting as well.”

The Alaska Volcano Observatory says that Okmok Volcano's six-mile-wide
caldera has several vents erupting simultaneously.
Billowing ash clouds are reaching heights of up to 20,000 feet as
seismic activity continues to fluctuate.
Geologists say they have been very busy trying to monitor not only the
Okmok eruption, but also the erupting Cleveland Volcano nearby.
'I can't remember the last time we
managed two eruptions at once, especially two so closely spaced on the
volcanic arc,' said Tina Neal with the Alaska Volcano Observatory.

Put the Okmok eruption together with the Chaitén
eruption, and I fear that we could have a problem.

20 Jun 08 - The last time Chaitén blew, the evidence indicates it vented
continuously for several months, which is why it is compared to the Tambora
1815 event, which created the “Year Without a Summer.”
