The most dense layer of the atmosphere is the troposphere is the most dense layer because it is at the bottom of the atmosphere. The troposphere is where all our weather happe â¦ ns. It also has the highest air pressure. But more specifically, the earths atmosphere is most dense at the surface.
Earthquakes on faults like these may cause tsunamis in the Puget Sound region. 'Deep' faults Deep faults can occur where two tectonic plates collide and one of the plates is forced beneath the other.
Generally the danger of a tsunami occurring exists where earth-and lake-quakes are possible, in areas where tectonic plates collide with each other, drift past each other or collide, as well as in other areas with geological faults. Mostly beaches and coastlines are affected by tsunamis.sunamis arise from the sudden displacement of gigantic water masses due to earthquakes on the seabed, volcanic eruptions above and under water, landslides or meteorite impacts. About 86 % of all Tsunamis result from so-called seaquakes.
