Yes, an EF5 tornado is survivable, but survival is statistically rare and highly dependent on circumstance. While these tornadoes are capable of inflicting complete destruction, leaving virtually nothing standing in their path, understanding the factors that influence survival can significantly increase your odds. Key elements include having access to appropriate shelter, heeding warnings promptly, and possessing a clear understanding of tornado safety protocols. Remember, while EF5 tornadoes are incredibly powerful, they are also rare, and preparedness is the best defense.
Understanding EF5 Tornadoes
What Makes an EF5 Tornado So Dangerous?
The Enhanced Fujita (EF) Scale rates tornadoes based on the damage they cause, correlating that damage to estimated wind speeds. An EF5 tornado is the highest rating, indicating estimated winds exceeding 200 mph. At this intensity, structures are not only damaged but often completely destroyed, with homes leveled, vehicles tossed, and debris becoming airborne missiles. The immense power of these storms makes any exposure extremely perilous.
The Role of Chance in Survival
It’s crucial to acknowledge that even with the best preparations, survival during an EF5 tornado involves a degree of chance. Freak accidents can occur, and the sheer force of the wind can overcome even seemingly robust structures. However, focusing on risk mitigation and informed decision-making can significantly shift the odds in your favor.
Key Factors Influencing Survival
The Importance of Shelter
- Underground Shelters: The most effective protection against an EF5 tornado is an underground storm shelter or a properly constructed basement. These locations offer the greatest shielding from wind and flying debris. FEMA-compliant shelters are designed to withstand extreme forces and offer the best chance of survival.
- Interior Rooms: If an underground shelter isn’t available, seek refuge in a small, interior room on the lowest floor of a sturdy building. Stay away from windows, doors, and exterior walls. Bathrooms and closets can provide some degree of protection, but reinforce these spaces if possible.
- Community Shelters: Many communities in tornado-prone areas have public storm shelters. Know the location of these shelters in advance and have a plan for getting there quickly when a tornado warning is issued.
Heeding Warnings and Staying Informed
- Tornado Watches vs. Tornado Warnings: Understand the difference. A tornado watch means conditions are favorable for tornadoes to develop. A tornado warning means a tornado has been sighted or indicated by weather radar, posing an imminent threat.
- Reliable Information Sources: Monitor local news, the National Weather Service, and weather apps for the latest updates and warnings. Have a NOAA Weather Radio on hand, as it can provide critical information even during power outages.
- Act Quickly: When a tornado warning is issued, take immediate action. Don’t hesitate or delay seeking shelter. Every second counts.
Preparing Your Home and Property
- Reinforcing Structures: Consider reinforcing vulnerable areas of your home, such as garage doors and windows. Storm shutters or impact-resistant glass can offer added protection.
- Securing Outdoor Items: Before a storm, secure or bring inside any loose outdoor items that could become projectiles, such as patio furniture, trash cans, and tools.
- Creating a Disaster Kit: Assemble an emergency kit with essential supplies, including water, food, medications, a first-aid kit, a flashlight, and a battery-powered radio.
Debunking Myths About Tornado Safety
The Southwest Corner Myth
The idea that the southwest corner of a basement is the safest is a myth. Tornadoes can approach from any direction. The best place to be is under a sturdy table or workbench, away from windows and exterior walls.
Opening Windows to Equalize Pressure
Opening windows during a tornado is not only ineffective but also dangerous. It won’t prevent the house from being damaged, and it exposes you to flying debris and strong winds.
Psychological Preparedness
Facing Fear and Panic
The psychological impact of a tornado can be significant. Prepare yourself mentally by practicing your safety plan and visualizing what to do in an emergency. Knowing you have a plan can reduce fear and panic during a real event.

After the Tornado: Staying Safe
Even after the tornado has passed, dangers remain. Stay informed about potential hazards, such as downed power lines, damaged structures, and debris. Be cautious when entering damaged areas, and wear protective gear, such as sturdy shoes and gloves.
EF5 Survival: A Matter of Mitigation, Preparation, and Luck
While the raw power of an EF5 tornado makes survival a challenge, a combination of preparation, informed decision-making, and a degree of luck can significantly increase your odds. By understanding the risks, taking appropriate safety measures, and staying vigilant, you can minimize your vulnerability and enhance your chances of weathering the storm.
Frequently Asked Questions (FAQs)
1. What is the survival rate of an EF5 tornado?
While statistically definitive survival rates for EF5 tornadoes are challenging to pinpoint due to the rarity and variability of these events, anecdotal evidence and general assessments suggest that even in violent tornadoes, the survival rate can be relatively high, often cited as 99% or greater for all tornadoes. This seemingly high percentage is somewhat misleading because this includes all levels of tornadoes, but survival drops drastically within the direct path of an EF5. However, keep in mind that this is a broad average. Survival is highly dependent on proximity to the tornado’s core and the availability of adequate shelter.
2. Has there ever been an F6 tornado?
The original Fujita scale did theoretically include an F6 rating, but it has never been officially used. Some tornadoes were initially considered for that rating, but later downgraded to F5. The Enhanced Fujita Scale doesn’t even have an F6.
3. How bad is an EF5 tornado?
An EF5 tornado is the most devastating type of tornado, characterized by estimated wind speeds exceeding 200 mph. It can completely destroy well-built structures, toss vehicles, and turn debris into dangerous projectiles. The scale is used mostly in North America.
4. Is there an F7 tornado?
No, an F7 tornado is hypothetical and doesn’t exist on either the original Fujita scale or the Enhanced Fujita scale. The concept is based on extrapolating beyond the known limits of observed tornado intensity.
5. Is a 40 mph tornado bad?
A 40 mph tornado is classified as an F-0 tornado, which causes light damage. This might include damage to chimneys, broken tree branches, and shallow-rooted trees being pushed over.
6. What are the rarest tornadoes?
EF-4 and EF-5 tornadoes are among the rarest and most destructive. They constitute a very small percentage of all tornadoes, but account for a significant portion of the damage and fatalities.
7. Is tornado alley shifting?
Yes, there’s evidence that tornado activity is shifting eastward, with an increase in tornadoes in states like eastern Missouri, Arkansas, western Tennessee, Kentucky, northern Mississippi, and Alabama.
8. How rare is an EF4?
EF4 tornadoes are quite rare, making up only about 1% of all tornadoes. They are characterized by three-second wind gusts of 166 to 200 mph.
9. Is a brick house safer in a tornado?
Brick houses offer better protection than homes made of lighter materials, but they are not tornado-proof. Brick can withstand higher wind speeds and impact from debris, but an EF5 tornado can still cause significant damage.
10. Is a 12-mile-wide tornado possible?
A tornado 12 miles wide is not possible based on current understanding. The widest tornado on record was the El Reno, Oklahoma tornado of May 31, 2013, which reached a maximum width of 2.6 miles.
11. Can a house survive an EF5?
It is highly unlikely for a standard house to survive an EF5 tornado intact. These tornadoes can level and blow away almost any above-ground structure. The primary objective is to seek shelter.
12. Can you survive an F5 tornado in a storm shelter?
Yes, properly constructed and FEMA-compliant storm shelters are designed to withstand the forces of an EF5 tornado, offering a high probability of survival.
13. How do you survive an EF5?
Survival during an EF5 tornado depends on:
- Seeking immediate shelter: Ideally in an underground storm shelter or a reinforced interior room.
- Protecting yourself from debris: Using blankets, mattresses, or helmets.
- Having emergency supplies: To sustain yourself after the storm.
14. When did the last EF5 happen?
The last EF5 tornado in the U.S. occurred on May 20, 2013, when a devastating tornado struck Moore, Oklahoma.
15. What was the scariest tornado?
The Tri-State Tornado of March 18, 1925, is considered one of the scariest and deadliest in U.S. history. It traveled through Missouri, Illinois, and Indiana, killing approximately 695 people and injuring over 2,000.
