Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
The upper limit for humans is considered to be 18 kHz. The upper and lower limits of elephant hearing are the lowest measured for any animals aside from the pigeon. [10] By contrast, the average best frequency for animal hearing is 9.8 kHz, the average upper limit is 55 kHz. [10]
Avalanches can be triggered spontaneously, by factors such as increased precipitation or snowpack weakening, or by external means such as humans, other animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees.
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .

Some animals have been thought to perceive the infrasonic waves going through the earth, caused by natural disasters, and to use these as an early warning. An example of this is the 2004 Indian Ocean earthquake and tsunami. Animals were reported to have fled the area hours before the actual tsunami hit the shores of Asia.
Every year tens of millions of people take part in a massive earthquake drill called the Great ShakeOut, which teaches people what to do and how to respond in case of a ground-rattling temblor.
