Tsunamis can vary greatly by length in terms of their size. The largest tsunamis last for a few days while regular ones last just a few hours.
Tsunamis that are triggered by volcanic eruptions
They cause tsunamis
this happens when the earth's tectonics plates have rubbed together for a long time on a fault line over a long time this pressure builds then suddenly releases and this a displacement of water ties to spread out, and this causes tsunamis it they happen to reach land and they are big. This is what I learnt
Tsunamis hit Japan regularly due to its location on the Pacific Ring of Fire, but they do not occur every year. Japan has a long history of tsunamis, with major events occurring every few years or decades. The country is well-prepared with early warning systems and evacuation procedures in place.
Unfortunately there is nothing we can do to prevent tsunamis.
the tsunamis can carry jellyfish along
Yes, of course, India can have tsunamis.
