Subtle Seismic Movements May Help Forecast Large Earthquakes

by JoAnna Wendel 1 February 20166 October 2021

Where a plate of Earth's crust slides under another and when frequent episodes of plate slippage occur without noticeable earthquakes, large temblors will more likely strike, a new study finds.

UAE-Oman Mountains Give Clues to Oceanic Crust and Mantle Rocks

by S. Pilia, M. Y. Ali, A. B. Watts and M. P. Searle 9 December 20157 October 2021

When oceanic plates meet continental plates, the continental plates usually come out on top. Cases where this is reversed provide valuable access to oceanic crust and mantle materials.
