Recovering after a disaster can be overwhelming. Check out what resources the Red Cross has to offer.
Before, During, and After an Earthquake
Explosive volcanoes blast hot solid and molten rock fragments and gases into the air. As a result, ashflows can occur on all sides of a volcano and ash can fall hundreds of miles downwind. Dangerous mudflows and floods can occur in valleys leading away from volcanoes. If you live near a known volcano, active or dormant, be prepared to follow instructions from your local emergency officials. Learn about your community warning systems and emergency plans.
Be prepared for the hazards that can accompany volcanoes:. In case family members are separated from one another during a volcanic eruption a real possibility during the day when adults are at work and children are at school , have a plan for getting back together. Make sure everyone knows the name, address, and phone number of the contact person. Get a pair of goggles and a throw-away breathing mask for each member of the household in case of ashfall.
Contact your local emergency management office or American Red Cross chapter for more information on volcanoes. Effects of a volcanic eruption can be experienced many miles from a volcano. Mudflows and flash flooding, wildland fires, and even deadly hot ashflow can reach you even if you cannot see the volcano during an eruption.
Avoid river valleys and low lying areas. Trying to watch an erupting volcano up close is a deadly idea. If you have a respiratory ailment, avoid contact with any amount of ash.
Stay indoors until local health officials advise it is safe to go outside. Remember to help your neighbors who may require special assistance — infants, elderly people, and people with disabilities.

Before Evacuation Although it may seem safe to stay at home and wait out an eruption, if you are in a hazardous zone, doing so could be very dangerous. Stay safe. Hot ash or lava from a volcanic eruption can rapidly melt snow and ice at the summit of a volcano.
The melt water quickly mixes with falling ash, with soil cover on lower slopes, and with debris in its path. This turbulent mixture is dangerous in stream channels and can travel more than 50 miles away from a volcano. Also intense rainfall can erode fresh volcanic deposits to form large mudflows.
If you see the water level of a stream begin to rise, quickly move to high ground. If a mudflow is approaching or passes a bridge, stay away from the bridge.

Puyehue Volcano in Chile, which last erupted in June causing the evacuation of 4, people, is once again showing signs of activity. Major roads, as well as crop areas, were covered by thick layer of ashes. In this situation, the health sector response has been swift. Health facilities assist the population during extended hours and the national authorities have already sent to the area , masks, eye drops, chlorine tablets and water purification equipment. Health recommendations in these cases are aimed to ensure quality control of air and drinking water, to prevent diseases caused by volcanic ash and to maintain sanitary conditions in shelters and waste disposal, among others.
A volcano is a rupture in the crust of a planetary-mass object , such as Earth , that allows hot lava , volcanic ash , and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging , and most are found underwater. For example, a mid-oceanic ridge , such as the Mid-Atlantic Ridge , has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates.
Official websites use. Share sensitive information only on official, secure websites. Alaska, Hawaii, California, and Oregon have the most active volcanoes, but other states and territories have active volcanoes, too. A volcanic eruption may involve lava and other debris that can flow up to mph, destroying everything in their path. Volcanic ash can travel s of miles and cause severe health problems.
Did you know there are more than active volcanoes in the United States and its territories? Nonetheless, millions of Americans live, work or vacation in places that could be affected by volcanic activity. An erupting volcano can blast ash, lava, solid rocks and gases into the air, creating hazards that can kill people, disrupt air travel and destroy property many miles away.
