Because some poor countries don't have safe buildings whereas rich countries do.
Landslides and other big impacts like volcanic eruptions cause mega tsunamis
Valleys
Yes, Tsunamis are usually triggered by earthquakes. More rarely they can be cause by landslides and volcanic eruptions.
Japan lies in the earthquake zone where four plates come together. As the plates push against each other, they cause violent earthquakes and volcanic eruptions.
Lava gets cooled by water and becomes land... Other than that I can't think of anything else that's good about a volcanic eruptions
Two types of volcanic eruptions are explosive eruptions, characterized by the violent ejection of lava, ash, and gases, and effusive eruptions, which involve the slow release of lava flows. Explosive eruptions are typically more destructive and can create volcanic ash clouds that pose hazards to aviation and human health. Effusive eruptions, on the other hand, can lead to the formation of lava plateaus and shield volcanoes.
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
landslides, earthquakes and volcanic eruptions
A tsunami can happen when there is a sudden movement in the ocean thatâ??s caused by a landslide or earthquake. The other cause of tsunami is volcanic eruptions or meteorite impact.
Tsunamis are most commonly caused by underwater earthquakes, where tectonic plate movements displace a large volume of water, creating a wave. Other causes can include volcanic eruptions, landslides, or asteroid impacts.
Plate interactions can cause earthquakes, volcanic eruptions, and the formation of mountains. These interactions occur at plate boundaries where plates are either moving apart, sliding past each other, or colliding.
