Iwo Jima earthquake 2026: a magnitude 5.5 event struck the Volcano Islands region on July 16, drawing a USGS PAGER green ...

Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs.

Here’s everything you’ll learn when reading this story: Scientists have long known that volcanic island arcs contain relatively high concentrations of gold, but the reason isn’t clear. A new study ...

Convergent plate boundaries, where one lithospheric plate descends beneath another, drive subduction and ultimately lead to arc-continent collision. In classical subduction settings, the downgoing ...
