How to Survive a Tsunami, According to Science


You’re on a beach. Not a worry in the world. The sun bronzing your skin, sand trickling between your toes, the sound of waves… wait, what? Better act quickly;
in a matter of minutes, you may be underwater. Here’s how to survive a tsunami, Tsunamis are triggered by
intense underwater activity, usually an earthquake, or
an underwater volcanic eruption. These events displace
huge volumes of water, pushing it up from the
ocean’s floor to its surface. But when gravity pulls it back down, all this built up energy
is released outwards, forming deadly waves
that grow stronger as they ripple across the ocean. A tsunami’s waves can be
100 km (62 miles) long, and sometimes taller
than 30 meters (100 ft)! They can travel across
whole oceans, moving at the speed
of a jet airplane. Even in a tsunami hazard zone,
you can still survive, if you know what to do. The Pacific ocean is home to
volatile tectonic activity, In most cases, an earthquake
comes before a tsunami. So if you’re near the coast,
and you experience an earthquake, protect yourself from that first. But once the shaking stops, move to higher ground
as quickly as possible. An early sign of an impending tsunami
is that water along the coast will recede. It pulls back and
exposes the sea floor. You’ll only be putting yourself at risk
for when the water surges back. Instead, head in the
opposite direction. Try to get as far as 3.5 km (2 miles)
from the ocean, or 30 metres (100 feet) above sea level
to ensure your safety. Tsunamis travel quickly, and you may not have enough
time to clear the hazard zone. In this case, look for a tall building,
with a sturdy concrete foundation. If you see one nearby, run inside and get to the
roof as quickly as possible. If you can’t make it
to a building in time, Though that might not
sound very practical, hold the eye-roll for a moment. In the 2004 Indian Ocean tsunami, an Indonesian woman
was finally rescued after holding onto a
palm tree for 5 days straight. While it isn’t ideal, if you can’t
get to higher ground in time, you need to find something
to hold on to. As the tsunami moves inland, it will
sweep tons of debris along with it. This can be very dangerous, as the accumulation of debris,
traveling at high speeds, become fatal obstacles for anyone
who’s been caught in the current. However, many tsunami victims
have been saved by climbing onto detached roofs or holding on tightly to floating cars
or other large objects. A tsunami isn’t one wave,
but a series of waves, known as a tsunami wave train. Waves may be anywhere from
5 minutes apart, to an hour apart. And be aware that the first wave
that hits isn’t always the strongest. So even when you think it’s over, stay where you’re safe
until you hear from local officials. It goes without saying,
tsunamis are terrifying. And when a 30 meter (100 ft) wave
is hurtling towards you at 800 km an hour (500 mph), you’re probably feeling pretty helpless. But, have faith in science,
trust empirical research, and you’ll see there’s
always a way out. We’ll keep showing you,

  1. Omg I’m so scared bc I live in New Zealand but I was like is New Zealand that dares and I looked at the news Spence Australia is only 2 hours away Australia is only close to Africa and afriaca is rare to a sunamiess so I’m safe for now but I live in France for a year in Paris Paris has no beaches but I’ll travel
