Vik, a small Icelandic town of just 300 people, where residents still recall stories from their relatives of Katla volcano's last eruption in 1918, sits under a blanket of cloud in this Sept. 27, 2011 photo. If Iceland's air-traffic paralyzing volcanic eruption in 2011 seemed catastrophic, just wait for the sequel. That's what many experts are saying as they nervously watch rumblings beneath a much more powerful Icelandic volcano - Katla - which could spew an ash cloud dwarfing eruption that cost airlines $2 billion and drove home how vulnerable modern society is to the whims of nature.
Remember when Eyjafjallajökull, that Icelandic volcano with the impossible name, erupted in spring 2010, disrupting air traffic all over the world and costing airlines and the global economy billions?

Child's play, The Associated Press reported over the weekend, if seismic activity from another Icelandic volcano with a history of nasty tantrums leads to an eruption.

Seismologists in Iceland are wary of an increasing number of small, 3- to 4-magnitude earthquakes under the volcano Katla, whose last eruption in 1918 proved deadly.

That eruption produced a noxious cloud that literally blacked out the sun, killing off crops and livestock, the AP reported.
