An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network...

Melt burst events in a dominantly amagmatic lithosphere at Gakkel Ridge in the Arctic Ocean

Abstract Alternation of magmatic and amagmatic seafloor along the slow and ultraslow spreading ridges is common. Yet, temporal variation is obscured by sediments blanketing oceanic basement away from spreading centers. Here we analyze aeromagnetic data covering zero age to ~35 Ma...
