How One Big Earthquake Triggers Another

How One Big Earthquake Triggers Another LiveScience Every so often, one large earthquake can trigger another. These "earthquake doublets" might happen because the first quake shifts stresses around in the Earth’s crust, triggering the second temblor, scientists say.

On Nov. 15, 2006 an 8.3 magnitude quake shook the Earth near the Kuril Islands, an archipelago off the southeast coast of Russia, and to the northeast of Japan. Within minutes, smaller quakes began shaking on the seaward side of the island chain. Then on Jan. 13, 2007 an 8.1 magnitude earthquake ripped through the upper portions of the Pacific plate to the east of the Kuril Islands.

Would only be logical but one thing we never here them saying is how does the earth being spherical can explain it.
