Medium Power JBox and Seismometer Central Caldera

Medium Power JBox and Seismometer Central Caldera

A broadband seismometer and a low-frequency hydrophone are being placed on a flat basaltic plateau at the Axial Seamount Central Caldera Site, awaiting connection to medium power J-Box MJ03F. On a follow-on dive a 4.6-km cable will be installed. This area is of particular interest because the caldera floor is rapidly being uplifted, suggesting that melt is migrating into the magma chamber below.
