Insight: Volcanoes of Great Beauty and Danger

The city of Seattle sits within the ‘Ring of Fire,’ an area of volcanoes that have the potential to erupt at any time.

Local tribal mythology tells the story of a pair of warriors, Wyeast and Pahto, who fought each other for the love of a beautiful maiden.

Their monumental battle involved earthquakes and firing volleys of rock and flames across the Columbia River. To settle the dispute, the gods transformed the warriors into mountains along the Cascade Chain: Wyeast became Mount Hood and Pahto became Mount Rainier.

Seattle sits on the Pacific Rim, where 850 active volcanoes in mountain ranges on all sides of the Pacific Ocean form a ‘Ring of Fire.’ This includes the Cascade Range, a 700-mile (1,130km) chain of mountains that runs north-south through the state of Washington. The most recent major volcanic eruption in the Cascades occurred in May 1980, when Mount St Helens gave a powerful demonstration of the natural forces that created much of the Northwest landscape. The eruption of ash and molten lava transfigured the hillsides and sent a gray cloud across the state. Repercussions were said to have been felt as far away as Europe.

As many as 60 people died, as well as 7,000 big game animals (deer, elk, and bear). Many small animals survived, however, because they were below ground level or the water surface.

Mount St Helens Eruption

On May 18, 1980, skies darkened as far away as Seattle as Mount St Helens, in southwestern Washington state, literally blew its top. The explosion took a cubic mile off the summit, reducing the mountain’s elevation from 9,677ft (2,950 meters) to 8,364ft (2,550 meters).

The volcano had shown signs of activity well before the blast, and although the region had been evacuated, the death toll reached as many as 60, as lava and mudslides flattened 230 sq miles (595 sq km) of forest. There was extensive damage to wildlife, and the ash-covered slopes and fallen trees serve as modern reminders of the day. The mountain continued to shudder with minor eruptions into the 21st century.
