Thunderstorm Protection Guide
- The best defense against thunderstorms is to stay inside a sturdy building or shelter that can protect you from deadly lightning, large hail, damaging winds, flooding rain, and tornadoes.
- Once in a shelter, stay away from windows and avoid electrical equipment and plumbing.
- Postpone outdoor activities until the storms have passed.
- If caught outside, take shelter in a sturdy enclosed building or hard top automobile immediately. Avoid open spaces, isolated objects, high ground, and metallic objects.
- Get out of boats and away from bodies of water. Remember, if you can hear thunder, you are close enough to the storm to be struck by lightning.
- If a tornado is spotted, act quickly and move to the lowest basement level of your shelter, putting as many walls between yourself and the outside as possible.

Landslide Protection Guide
- Know the landslide risk in your area.
- Learn about the types and signs of landslides common in your area.
- Know your community's landslide evacuation plans.
- Gather supplies in case you have to leave immediately or if services are cut off. Keep in mind each person's specific needs, including medication.

Tsunami Protection Guide
- All earthquakes do not cause tsunamis, but many do. When you know that an earthquake has occurred, stand by for a tsunami emergency message.
- An earthquake in your area is one of nature's tsunami warning signals. Do not stay in low-lying coastal areas after a strong earthquake has been felt.
- Tsunamis are sometimes preceded by a noticeable fall in sea level as the ocean retreats seaward exposing the seafloor. A roar like an oncoming train may sometimes be heard as the tsunami wave rushes toward the shore. These are also nature's warning signals.
- A tsunami is not a single wave, but a series of waves carrying a massive volume of water that can flood and inundate land for hours. The first wave may not be the largest. Stay out of danger areas until an "all-clear" is issued by a recognized authority.
- A small tsunami at one point on the shore can be extremely large a few kilometers away. Don't let the modest size of one make you lose respect for all.
- All warnings to the public must be taken very seriously, even if some are for non-destructive events.
- All tsunamis are potentially dangerous, even though they may not damage every coastline they strike.
- Never go down to the shore to watch for a tsunami. When you can see the wave, you are too close to outrun it. Most tsunamis are like flash floods full of debris. Tsunami waves typically do not curl and break, so do not try to surf a tsunami.
- Sooner or later, tsunamis visit every coastline in the Pacific and all oceans. If you live in a coastal area, be prepared and know nature's tsunami warning signals.
- During a tsunami emergency, your local civil defense, police, and other emergency organizations will try to save your life. Give them your fullest cooperation.
Volcano Eruption Protection Guide
Before the eruption
- Know your area's risk from volcanic eruption.
- Ask local emergency management for evacuation plans, and for potential means of protection from ash.
- Learn about community warning systems.
- 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.
- Keep important documents in a safe place.
During the eruption
- Listen to alerts. 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 well-fitting, certified facemask.
- Avoid driving in heavy ashfall.
After the eruption
- Listen to authorities to find out when it is safe to return after eruption.
- Send text messages or use social media to reach out to family and friends. Phone systems are often busy after a disaster.
- 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.
