Short summary
Sediments containing hydrates dispersed in the pore space show a characteristic seismic anomaly: a high attenuation along with increasing seismic velocities. Recent major findings from synchrotron experiments revealed the systematic presence of thin water films between quartz and gas hydrate. Our numerical studies support earlier speculation that squirt flow causes high attenuation at seismic frequencies but are based on a conceptual model different to those previously considered.
