A supervolcano is like a regular volcano on steroids.
If it erupts, it would kill 100,000 people in an instant.
And expel over a thousand times more material than a regular volcano.
It would send so much ash and dust into the atmosphere that it could
make an entire continent uninhabitable. Oh, and then there are the toxic gases
and landslides that come along with the eruption, but we'll get to those later.
Here’s How to Survive a Supervolcano There are about 20 supervolcanoes on Earth,
with one of the most famous being found in Yellowstone National Park in the United States.
It's had three massive eruptions in the last 2 million years,
and scientists suggest that the fourth could be right around the corner.
So you better be ready if it or another geological monster like it decides to blow.
Step 1. Recognize the Signs Once lava bursts out of the volcano, it’ll
destroy everything in its path. At the same time, tephra, the pieces of magma that get blasted into
the air, can crush houses, cars and block roads. So you’d need to put as much distance between you
and the volcano before the destruction begins. Usually, volcanoes give off warning signs hours
before an eruption. These can include temperature changes and earthquakes.
Step 2. Turn Off the Air Conditioning
While burning hot lava scorching everything it touches sounds like the worse thing that can
happen, you shouldn’t underestimate the ash. Falling ash can turn into a thick pile 3
m (9.8 ft) deep, even 1 km (.62 mi) away from the eruption.
If you’re within that range, you need to protect your respiratory system. Wear a face mask,
preferably that N-95 you still have lying around from the COVID pandemic.
When you’re finally safe from the lava flow, turn off your car. The ash can clog engines and stall
vehicles. It might also be hot with the windows rolled up, but don't use your AC or fans. That
will only bring more ash into your car. Step 3. Prepare for the Worst
Whether you live in an area at risk for a volcanic eruption or you're just in the
wrong place at the wrong time, you need to plan for the imminent danger ahead of you.
Check social media for evacuation and shelter plans. You'll also need to see if there are
protective measures in place against the ash. Fill a bag with non-perishable food and water
for several days in case you're ordered to evacuate immediately.
Take into consideration that emergency clinics might be overloaded after the eruption, so grab
bandages, disinfectant wipes and hand sanitizer to take care of basic cuts and bruises. Even that jar
of honey in your cupboard can help heal wounds. Step 4. Stay Indoors
Just in case the toxic gas and falling ash are keeping you from leaving the disaster zone,
the eruption could also form lahars you need to watch out for. These are highly destructive
landslides that can devastate large areas. If you found shelter, stay inside. Make
sure you close all windows and doors. The most important thing to do is listen
to local officials and experts. Never try to do anything that they warn you against.
Step 5. Be Ready for Chaos Just like any apocalyptic
scenario, the aftermath of an eruption of a supervolcano like Yellowstone's would make
finding food and water extremely difficult. Global temperatures could drop for years,
destroying crops, killing animals and wreaking havoc with water supplies.
Even if you're stocked up on supplies, these will eventually run out. What would you do next?
How could you stay alive without food or water? Here’s a clue. You'll need to memorize
the life-saving rules of three theory. We'll tell more about that here, on How to Survive.
