Submarine landslides are one of the most dangerous tsunami sources. They can displace huge amounts of sediments from the continental slope into the deep ocean. Due to their long period signal, landslides can not be easily detected and recognized by common seismological methods. Here we present a method of detecting huge submarine landslides by means of tiltmeters, as a possible tool in future tsunami early warning systems. The dislocation of several hundred cube kilometers of sediment produces an elastic response of the earth. We analyze this response with a mathematical model and calculate the theoretical tilt signal. Further we describe an inversion routine providing the slide volume as well as the maximum slide velocity.
