The discovery of an unexpectedly hot rock beneath Earth's surface is challenging scientists' understanding of how heat is ...

Mariana Islands earthquake M5.1 on October 5, 2026 triggered no tsunami and no advisory, because this Pacific subduction zone is formally classified as aseismic: the only plate boundary on Earth that ...

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, revealing that these ...

Large earthquakes nucleate at tectonic plate boundaries, and their occurrence within a plate’s interior remains rare and poorly documented, especially offshore. The two large earthquakes that struck ...

PM on September 30, 2026, a magnitude 5.9 earthquake occurred near Yonaguni Island, with a maximum seismic intensity of 3 observed in Yonaguni Town, Okinawa Prefecture.The focal depth was 20 km."The e ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...

The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates sinking back into the interior through subduction zones. Subduction is thus a key ...

Magmatic intrusions, eruptions and flank collapses are frequent processes of volcano dynamics, inter-connected at different space and time scales. The December 2018 recrudescent episode at Mt. Etna is ...

One longstanding enigma in geology is how one tectonic plate can break Earth's rock-hard shell and begin diving under another in the process known as subduction. "We now know how subduction nucleated ...
