How do volcanic eruptions affect air travel?

When a volcano erupts the ash cloud it produces can pose a threat to aircraft flying in the area. This is because volcanic ash is hard and abrasive and can damage propellers and turbocompressor blades as well as scratching cockpit windows which impairs visibility.

How do volcanoes affect aviation?

In the high atmosphere where commercial aircraft circulate volcanic ash can cause engine malfunction damage turbine blades or Pitot electronic probes. Commercial jet airplanes are the ones that suffer the most serious damage when they fly through clouds that contain debris and gases produced by volcanic eruptions.

Why is Mt St Helens active?

Scientists from the U.S. Geological Survey Oregon State University and the University of Canterbury in New Zealand found that the mountain is sitting right on top of the spot where two tectonic plates were welded together millions of years ago. That created a weak point where magma can rise up through the crust.

Why did Mt St Helens erupt?

The landslide exposed the dacite magma in St. Helens’ neck to much lower pressure causing the gas-charged partially molten rock and high-pressure steam above it to explode a few seconds after the landslide started. Explosions burst through the trailing part of the landslide blasting rock debris northward.

What does an active volcano do?

Active volcanoes have a recent history of eruptions they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock called magma collects.

Which volcano is not showing any activity?

Dormant: Now things get a little dicier. The USGS defines a dormant volcano as any volcano that is not showing any signs of unrest but could become active again. California’s Shasta is a dormant volcano by that definition (although could be considered “active” by some because it has erupted in historic times.)
