Bottom Pressure and Tilt

Bottom Pressure and Tilt sensors are designed to measure the inflation and deflation of the seafloor using a precision pressure sensor that enables detection of the seafloor’s rise and fall (i.e., “breathing”) as magma (molten rock) moves in and out of underlying magma chambers. A very precise tilt meter (measures in micro-radians) records the “tilting” of the seafloor as it deforms in response to melt migration.
