Short summary
RHUM-RUM is a German-French project to record motion of the sea-floor caused by earthquakes around La Réunion. For this, 57 autonomous ocean-bottom seismometers were installed for one year in an area of 2000 × 2000 km around the island. These 57 were of two different types (Kiel-built LOBSTER and LCPO2000 from Scripps), whose performances are reviewed here. It was found that the LCPO2000-type is better suited for low frequencies, at the cost of higher power consumption and more difficult handling.
