Seismic monitoring of a glacial outburst flood initiated by the drainage of an ice-dammed lake. Seismic stations were installed on the glacier, whereas sensors were sunk about three meters into the ice. In total five stations were set up, whereas three stations were equipped with 3-component borehole sensors and two stations with tripartite arrays. The used sensors were 4.5Hz geophones (GS-11D), sampled with 500Hz.
