In the May 2 issue of The California Aggie,the article "UCD researchers aim to shed light on eruption frequency" states thatMt.Tambora had a major eruption in1812that had a devastating effect onNorthern Europe.This is incorrect.The volcano reached its seismological peak in1812,with a series of small eruptions.The major eruption,which led to what would be known as "The year without summer," occurred in1815.The Aggie regrets the error.
