Plate spreading rate
The ridge is a medium rate spreading center, moving outwards at a rate of approximately 6 centimetres (2.4 in) per year. Tectonic activity along the ridge is monitored primarily with the U.S. Navy's Sound Surveillance System (SOSUS) array of hydrophones, allowing for real time detection of earthquakes and eruptive events. The Juan de Fuca Plate is being pushed east underneath the North American Plate, forming what … WebbWhat would have to happen in Earth's core to stop plate motion? if there were no residual heat left and radioactive decay of elements in the core would have to end The spreading …

Webb17 sep. 2024 · Spreading rate is computed both as a full spreading rate (values reported in this study), which calculates spreading velocities between two sets of isochrons at the time of crustal accretion, and a half spreading rate, which is calculated relative to the mid-ocean ridge and takes into account spreading asymmetry. WebbAs the plate spreading rate decreases from 4.3 cm yr-' at the 16-17 ON area to 2.7 cm yr-' at the 22-23 ON area, axial ridge topography changes from higher than the thermal isostatic equilibrium position to lower than the isostatic position. The low axial topography at the 22-23"N area can be explained by the existence of a low
