Differential Uplift between BPRs at MJ03E & MJ03F


This page displays the Differential Uplift between two Bottom Pressure Recorders (NANO-BPRs) at OOI-RCA nodes MJ03E (Eastern Caldera) and MJ03F (Central Caldera) at Axial Seamount. It is calculated by simply subtracting the depth from the BPR at MJ03F (Central Caldera, which has the highest inflation rate) from the BPR at MJ03E (Eastern Caldera, which has the lowest inflation rate). This differential uplift is a clearer representation of the volcanic inflation signal, because it removes the "noise" of tidal residuals and oceanographic effects that are common to both stations, which are <5 kilometers apart. We then use the average rate of Differentail Uplift for the last 1 month on the Forecasting Method #2 page, the rate from the last 3 months on the Forecasting Method #3 page, and the rate from the last 6 months on the Forecasting Method #4 page to extrapolate into the future.
