Ring O Fire Is!

The USGS new volcano site with world map sums it all up: the Ring of Fire is where the action is. Except for the always spewing big island of Hawaii, all of the activity is happening as the (mostly) Pacific plate is being subducted beneath the adjacent continents. The Kuril Islands and Kamchatka peninsula rumble on in the northwest Pacific, the Indonesia/New Guinea archipelago have several on the list and Popo outside Mexico City continues its current eruption cycle. The rest of the list are frequent visitors to the active list.
If your journeys take you to the Pacific rim, check out your planet in action. The active rock cycle and constant change of the largest of the terrestrial planet is likely a large part of why we are here. But, there is nothing but change so stay mindful of the fact that Earth is still very much in charge.
