How to Survive a Tsunami (RE-CUT)

you're on a beach not a worry in the world the Sun bronzing your skin Sam trickling between your toes the sound of waves wait what where did all the water go did you see it going out now what better act quickly in a matter of minutes you may be underwater here's what you can do 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 oceans 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 tsunamis waves can be 100 kilometres long and sometimes taller than 30 metres they can travel across whole oceans moving at the speed of a jet airplane so with such speed strength and stamina how does anyone stand a chance even in a tsunami hazard zone you can still survive if you know what to do the first step to survival is to be able to identify the early signs of a tsunami the Pacific Ocean is home to volatile tectonic activity which explains why 75% of the world's volcanic eruptions and 90% of the world's earthquakes occur in the Pacific these geological disturbances are the reason why 85% of all tsunamis happen in the Pacific Ocean in most cases an earthquake comes in for a tsunami so if you're near the coast and you experienced an earthquake protect yourself from that first but once the shaking stops move to higher ground as quickly as possible the beach will grow bigger run the other way an early sign of an impending tsunami is that the water along the coast will receive it pulls back and exposes the seafloor do not go to the beach to investigate you'll only be putting yourself at risk for when the waters is back instead head in the opposite direction try to get as far as three and a half kilometers from the ocean or 30 meters above sea level to ensure your safety get to the highest elevation possible 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 your best bet is to grab on to something and hold on 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 on to a palm tree for five 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 caught in the current however many tsunami victims have been saved by climbing on two detached roofs or holding on tightly to floating cars or other large objects of course if you've made it this far your troubles aren't over yet a tsunami isn't one wave but a series of waves known as a tsunami wave train waves may be anywhere from five 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 wave is hurtling towards you at eight hundred kilometers per hour 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 one episode at a time on how to survive [Music] you
