Iceland volcano eruption, part deux?

Via Modern Survival Blog, comes this news:

On May 17, 2010 08:32 UTC, The Iceland Met office indicates that a small earthquake has occurred at the Katla location. In what could be an early indication of the event that is expected to occur (an eruption of Katla), a small earthquake is reported at the site. Although a single earthquake is not a precursor of an eminent eruption, it could be the first ’sigh’ of the awakening powerful giant.

Historically, Katla has erupted after the eruption of it’s close neighbor, Eyjafjallajokull, which first erupted on April 14, 2010 and is ongoing at this moment. Magma channels beneath the two volcanoes are thought to be interconnected. A Katla eruption would likely be about ten times as powerful at the Eyjafjallajokull eruption and could cause worldwide disruption while expelling huge volumes of volcanic ash into the stratosphere which would circle the globe potentially for years, depending upon the magnitude of the eruption. [emphasis added] ...

If such a large eruption does occur, expect food prices to large, as harvest yields plummet. Some more info on Katla's previous eruptions is available here. How's that food storage plan coming along?
