Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth’s surface.

What to do during an ash fall

1. Stay indoors.
2. Close windows and doors.
3. Do not run air-conditioning or clothes dryers.
4. Listen to the radio for advice and information.
5. If outside seek shelter; use a mask or handkerchief for breathing.
6. If possible do not drive, park your car under-cover or cover it.

Volcanic ash affects aircraft in a number of different ways. However, by far the most vulnerable part of an aircraft flying through a cloud of volcanic ash is its engines. When volcanic ash, which is usually already very hot, enters a jet engine, it heats can melt and stick together as clumps of molten material.

Volcanic ash ejected into the atmosphere by explosive eruptions has known damaging effects on aircraft. Ash particles can abrade forward-facing surfaces, including windscreens, fuselage surfaces, and compressor fan blades. Ash contamination also can lead to failure of critical navigational and operational instruments.

The ash contaminates fuel and water systems, can jam gears, and make engines flameout. Its particles have low melting point, so they melt in the engines’ combustion chamber then the ceramic mass sticks to turbine blades, fuel nozzles, and combustors—which can lead to total engine failure.

Yes. Jet engines and other aircraft components are vulnerable to damage by fine, abrasive volcanic ash, which can drift in dangerous concentrations hundreds of miles downwind from an erupting volcano. …

Radar data can be used to estimate concentration and the mean size of ash particles (e.g., Marzano et. Volcanic ash in the atmosphere can be detected and tracked with radars operating at various wavelengths. The S-band WSR-88D radars have been designed to monitor severe weather and to measure precipitation.

Volcanoes continue to erupt around the world, from Iceland to Ecuador and from Chile to Africa, causing disruption to air travel. Airspace monitoring and flight operational procedures have been put in place and commercial jet aviation has been operating safely in areas with volcanic eruptions.

No. If you were to fly through a relatively dense cloud of ash, like straight over the volcano itself, you could be in trouble. There have been cases of aircraft with engine outage situations but that is because the ash density has been quite high in those areas. It’s not just the engine.

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.

Consider using an indoor air cleaner or air conditioner, and prevent tracking ash into the house. Use an N95 mask to reduce exposure to ash if you need to be outside and especially during clean up. If ash is re-suspended by human activities, such as cleaning or driving, wear a dust mask during those activities.

Pneumonoultramicroscopicsilicovolcanoconiosis is a type of lung disease that is caused by inhaling very fine volcanic ash and sand dust, according to the Oxford dictionary. It was created by the president of the National Puzzlers’ League in 1935 during its annual meeting.
