Answer:
A - Earthquakes
Step-by-step explanation:
Earthquakes are the only common natural event for the west coast...
-Earthquakes can appear anywhere.
-Hurricanes are normally in the South east (around Florida)
-Blizzards are normally northern, for instance you can see a blizzard in New York (New York is in the North east of the USA)
-Volcanos, volcano eruptions are normally rare, but there are active volcanos in the U.S.A such as in Hawaii (Hawaii isn't actually on a coast... it is a chain of islands to the south of the USA) (But this doesn't mean there isn't volcanos in or near the west coast, there is but most are not active, and they don't really do much)
-In conclusion Earthquakes is the correct answer
I hope you have a good day!
