Ash Fall 1
Ash Fall 1 : Explosive volcanic eruptions produce fine material called volcanic ash, which is carried upwards in a buoyant eruption column before it settles out downwind to form ash fall. Ash falls can blanket the entire landscape for kilometres around a volcano, and may even reach nearby islands. Close to the eruption vent, ash may be thick enough to collapse buildings and destroy vegetation. Ash can cause aircraft, ship and car engines to malfunction. Ash can also be very dangerous to the health of people and animals since ash may cause serious respiratory problems if inhaled. Ash falls can be particularly damaging to livestock as small amounts of ash can lead to fluorosis if ingested. This hazard from ash fall may persist long after the eruption itself has ended
