Earthquakes.
Frequent shallow earthquakes
Earthquakes and tsunamis.
Earthquakes and eruptions.
Shallow focus earthquakes are associated with divergent and transform plate boundaries. These earthquakes typically occur within the top 70 kilometers of the Earth's crust and are caused by the movement of tectonic plates against each other.
Earthquakes and volcanoes! Also earthquakes can in turn cause tsunami.
Magma is generally associated with volcanoes
Earthquakes and volcanoes. Earthquakes may also cause tsunami.
Earthquakes are usually associated with the shifting of tectonic plates beneath the Earth's surface. The sudden release of energy due to this shifting causes seismic waves to radiate outwards, resulting in ground shaking. Earthquakes can also be associated with volcanic activity or human activities such as mining or reservoir-induced seismicity.
