Lava flows and a series of earthquakes have now been followed by large clouds of toxic fumes, emitting extremely dangerous particles, from Hawaii’s erupting volcano, Kilauea.
Authorities warned the public to stay away from the caustic plumes, caused by a chemical reaction when lava poured into the Pacific ocean.
Further eruptions and earthquakes have been forecast for weeks and months to come.
Here are the most complete guidelines from Ready.gov website.
A volcano is an opening in the Earth’s crust that allows molten rock, gases, and debris to escape to the surface. 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 100 mph, destroying everything in their path. Volcanic ash can travel 100s of miles and cause severe health problems. A volcanic eruption can:
- Contaminate water supplies.
- Damage machinery.
- Reduce visibility through smog and harmful gases that may threaten low-lying areas.
- Make it hard to breathe and irritate the skin, eyes, nose, and throat.
IF 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.
HOW TO STAY SAFE WHEN A VOLCANO THREATENS:
WHAT TO DO NOW: Prepare
- Know your area’s risk from volcanic eruption.
- Ask local emergency management for evacuation and shelter plans, and for potential means of protection from ash.
- Learn about community warning systems. The Volcano Notification Service (VNS) is a free service that sends notifications about volcanic activity. Sign up for alerts at https://volcanoes.usgs.gov/vns2/.
- Get necessary supplies in advance in case you have to evacuate immediately, or if services are cut off. Keep in mind each person’s specific needs, including medication. Do not forget the needs of pets.
- Consult your doctor if you have existing respiratory difficulties.
- Practice a communication and evacuation plan with everyone in your family.
- Have a shelter-in-place plan if your biggest risk is from ash.
- Keep important documents in a safe place. Create password-protected digital copies.
- Find out what your homeowner’s insurance policy will cover when a volcano erupts.
WHAT TO DO DURING: Survive
- Listen to alerts. The Volcano Notification Service provides up-to-date information about eruptions.
- Follow evacuation orders from local authorities. Evacuate early.
- Avoid areas downwind, and river valleys downstream, of the volcano. Rubble and ash will be carried by wind and gravity.
- Take temporary shelter from volcanic ash where you are if you have enough supplies. Cover ventilation openings and seal doors and windows.
- If outside, protect yourself from falling ash that can irritate skin and injure breathing passages, eyes, and open wounds. Use a well-fitting, certified facemask such as an N95. The Centers for Disease Control and Prevention (CDC) has a list of certified masks and the maker’s instructions on how to use the masks.
- Avoid driving in heavy ash fall. If you must drive, then turn off your vehicle’s headlights.
WHAT TO DO AFTER: Be Safe
Listen to authorities to find out when it is safe to return after an eruption.
- Send text messages or use social media to reach out to family and friends. Phone systems are often busy after a disaster. Only make emergency calls.
- Avoid driving in heavy ash. Driving will stir up volcanic ash that can clog engines and stall vehicles.
- If you have any breathing problems, avoid contact with ash. Stay indoors until authorities say it is safe to go outside.
- Do not get on your roof to remove ash unless you have guidance or training. If you have to remove ash, then be very careful as ash makes surfaces slippery. Be careful not to contribute additional weight to an overloaded roof.
