I agree with BlueString19, and it's even not possible to have earthquakes at all rings of fire at once. As earthquakes are generated by two neighbouring tectonic plates moving in different directions, this would require all tectonic plates to go in circles. The magma tectonic plates float on is so far not known to move in circles.
