On page 15 of the text, the date given when the Aviation Color Code and Volcano Alert Level were lowered to GREEN and NORMAL, respectively, for Shishaldin Volcano is incorrect. Originally, this date was shown as April 16, but this was the date previously given for the lowering of the volcano’s status to YELLOW and ADVISORY on page 14. The correct date and time when the Aviation Color Code and Volcano Alert Level were lowered to GREEN and NORMAL—June 24 at 20:00 UTC (12:00 AKDT)—has been revised on page 15 in this current version.
