The Full Story
The Novarupta eruption on the Alaska Peninsula in June 1912 was a massive VEI-6 event. It released an enormous volume of ash and pyroclastic material, forming the Valley of Ten Thousand Smokes. For decades, it was recognized as the largest eruption of the 20th century until Pinatubo was studied in more detail. The eruption transformed the surrounding landscape and had major scientific value for studying explosive volcanism. Novarupta remains a landmark in North American volcanic history.
