no matter where you live, a city always issue a warning siren, you should familiarize the sirens used for emergencies. they should give you a warning, and in this case, move to a higher ground. theres no time to drive yourself off the area, keep a presence of mind, and be optimistic.
it will make a even bigger tsunami
One tsunami would be the 2004 Indian Ocean tsunami.
They are about the same, but if I had to say: Tsunami.
no because it would take to long and the tsunami would have caught up with you
Niether. In the unlikely event that a tornado and a tsunami met, the tornado would go right over the tsunami and neither would be significantly affected.
Its still called a tsunami. There was a big Tsunami there in 1861/62
That would depend on where the tsunami struck and how big it was. Much of Australia's coastline is very sparsely populated, but a tsunami hitting one of the coastal towns or cities would wreak havoc.
There are no atmospheric conditions that portend a tsunami because a tsunami is just a wave, not at all tied to the atmosphere.
Yes. All manners of marine animals can be brought on shore by a tsunami. Note, though that a shark brought on shore by a tsunami would be stressed enough that it would not be interested in eating.
tsunami
expected a few hours after the original tsunami.
What you're probably thinking of is the ML scale which measures "potential energy" of the tsunami. Don't get this confused with electrical potential (or voltage). they are not the same. the "potential energy" of a tsunami, I would assume, would be measured in joules.
