Note that the Kamchatka Peninsula has Earthquakes synchronous and antipodal with South Sandwich Islands EQ’s. Just as EQ’s in the Vanautu, Loyalty, Kermadec and New Zealand region are synchronous and antipodal to Mt. Etna and Greek EQ’s. And, as Central Indian Ridge EQ’s are synchronous and antipodal to the NMSZ!!!
