Tsunamis are long wavelength waves. With this in mind the wavelengths of tsunamis can be in the hundreds of miles. Half the length of the wavelengths is how far down the water column waves effect the water. So basically no, swimming down 30 feet would not help you and you would still be swept up/hit by the wave.
thus, Is a lava tsunami real?
During eruptions, volcanic tsunamis can be caused by underwater explosions and shock waves caused by large explosions – even ones that occur above the waterline. Shock waves coupling with sea waves can produce tsunamis up to three meters in height.
Besides, Can you survive a tsunami with a life jacket?
They remained afloat and the heads were higher than the water level. As our experiments demonstrated, it can be concluded that when people are engulfed within tsunami waves, PFDs will provide them with a higher chance of survival because they will remain on the surface of tsunami waves and are still able to breathe.
then Where is the safest place to be during a tsunami? Should a tsunami occur and you cannot get to higher ground, stay inside where you are protected from the water. It’s best to be on the landward side of the house, away from windows. Often tsunamis occur in multiple waves that can occur minutes apart, but also as much as one hour apart.

Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees. Remarkably, only two fatalities occurred.
What happens if a tsunami hits a volcano? Having this happen would cause a lot of smoke and ash to rise into the air and affect our oxegen. It would also cause damage to the nearby area.

If you are faced with a breaking tsunami wave, diving to the bottom will be of no benefit. Climb something likely to withstand the power of the water. Don’t go to sea unless you can get to deep water (600 feet) before the wave hits.
How far inland would a 1000 Ft tsunami go?
Tsunamis can travel as far as 10 miles (16 km) inland, depending on the shape and slope of the shoreline. Hurricanes also drive the sea miles inward, putting people at risk. But even hurricane veterans may ignore orders to evacuate.
How long do you have after a tsunami warning?
Experts believe that a receding ocean may give people as much as five minutes’ warning to evacuate the area. Remember that a tsunami is a series of waves and that the first wave may not be the most dangerous. The danger from a tsunami can last for several hours after the arrival of the first wave.

Can a volcano cause lightning?
What is volcanic lightning? … During an explosive volcanic eruption, ash, rock, lava, and sometimes water collide, creating electrical charge in the eruption plume, and if the charge build up is high enough, lightning occurs. Not all volcanic eruptions produce lightning.
Can a volcano cause a hurricane?
According to their findings, large tropical volcanic eruptions can affect hurricanes by shifting the Intertropical Convergence Zone, a region that circles the Earth near the Equator and greatly influences rainfall and hurricane activity. … These changes can last for up to four years following the eruption.
How does a volcano cause a tsunami for kids?
The lava flowing out of the volcano displaces the water around it. That water can turn into a large wave. If the earthquake or volcano is very big, then the wave can be very big, too. Big tsunamis usually begin in the deep ocean, where a large volume of water can be displaced.

Can you survive a tsunami in a submarine?
2. The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.
