Mount Rainier eruption could severely disrupt flights around Seattle

Volcanic eruptions can cause prolonged disruptions to air travel. The Eyjafjallajökull eruption led to two weeks of flight cancellations across Europe, costing the aviation industry billions. If Seattle-Tacoma International Airport were affected by an ash cloud from Mount Rainier, it could lead to similar financial losses and extensive flight cancellations.

Volcanic ash is hazardous for aircraft as it can damage jet engines and impair visibility. Historical incidents like British Airways Flight 9 highlight these dangers when flying through volcanic ash clouds.

Efforts to improve detection and tracking of volcanic ash clouds have advanced since past eruptions. A collaboration between NASA and NOAA allows for near real-time detection using satellite technology, enhancing safety measures for airlines operating near active volcanoes.

If Mount Rainier were to erupt today, modern technology would enable faster responses compared to past events like Eyjafjallajökull's eruption. However, given its proximity to the volcano, Seattle-Tacoma International Airport might still face significant operational challenges.

The Armero tragedy in Colombia serves as a grim reminder of lahar dangers; over 20,000 people perished due to mudslides following a volcanic eruption in 1985. With more glaciers than Nevado del Ruiz had at that time, Mount Rainier presents an even greater risk if it erupts.

Scientists remain vigilant about Mount Rainier's activity due to its potential for widespread destruction both in terms of human life and economic impact on aviation industries globally.
