Static stress change models for known or hypothesized faults in the Hispaniola and Puerto Rico subduction segments due to (a) slip on a patch of the Puerto Rico subduction zone, and (b) slip on a patch of the Hispaniola subduction zone. An open arrow denotes slip direction and the patches are marked by dashed rectangles.

USGS research geologist Curt Storlazzi installs an instrument package on the seafloor of Maunalua Bay, Oʻahu. The platform, called a MiniPROBE, hosts six upward-looking acoustic Doppler current profilers (ADCP), seven conductivity and temperature (CT) sensors, and eight self-logging optical backscatter sensors (SLOBS).

USGS scientists from the Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California deploy an instrument called the poking eyeball. The system, developed by PCMSC, was designed to take repetitive microscopic images of the seabed from a tripod on the seafloor.
