KArlsruhe BroadBand Array (KABBA)

KABBA is a broadband seismometer array which is capable of measuring seismic waves with high precision anywhere on our planet. The array currently consists of 38 broadband sensors and corresponding recording equipment. Broadband indicates the wide range of frequencies which the instruments can measure. Sensors from the KABBA array are deployed for temporary seismic experiments all over the world.
