Short-period Seismometer at Mothra

Short-period seismometers provide real-time information on earthquakes at mid-ocean ridges. In 2003, an array of seismometers was deployed on the Endeavour Segment of the Juan de Fuca Ridge, north of Axial Seamount. The one shown here, was deployed inside a borehole in a pillow basalt in the Mothra Hydrothermal Field, providing better coupling to the seafloor. This project was funded by the W.M. Keck Foundation.
