Signs of Impending Volcanic Eruptions and Safety Measures.

  Safety Measures when : Before, During, After I F YOU ARE UNDER A VOLCANO WARNING: Listen for emergency information and alerts. Follow evacuation or shelter orders. If advised to evacuate, then do so early. Avoid areas downstream of the eruption. Protect yourself from falling ash. Do not drive in heavy ash fall. Cloth masks help prevent the spread of COVID-19, but they will not adequately protect you from inhaling ash for longer periods of time like a  respirator  will. Respirators, like an N-95, are not meant to fit children. Due to COVID-19, it may be difficult to find respirators, such as N-95s. Reduce your ash exposure by doing the following: Limit your time outdoors and use a dust mask or cloth mask as a last resort. Avoid areas downwind and river valleys downstream of the volcano. Take temporary shelter from volcanic ash where you are. Cover ventilation openings and seal doors and windows. Avoid driving in heavy ash. If you must drive, keep the windows up and do not use the air

  Signs of Impending Volcanic Eruption The  importance of  studying warning  signs  can help prevent potential human loss. By examining clues, scientists can develop a course of action and evacuation plan for people that live within the vicinity of an  impending volcanic eruption . 1. Increase in the frequency of volcanic quakes with rumbling sounds; occurrence of volcanic tremors. 3 .Crater glow due to presence of magma at or near the crater. 4. Ground swells (or inflation), ground tilt and ground fissuring due to magma intrusion. 5.Localized landslides , rockfalls and landslides from the summit area which not attributable to heavy rains. 6.Noticeable increase in the extent of drying up of vegetation around the volcano’s upper slopes. 7. Increase in the temperature of hot springs , wells crater lake near the volcano; 8. Noticeable variation in the chemical content of springs , crater lakes within the vicinity of the volcano; 9. Drying up of springs/wells aroun
