Seismic recordings with bell ringing signals in four European locations to mark the passage of time: Lunas (France), Riolos (Greece), Sta. Marيa de Montmagastrell (Spain) y Oriolo (Italy). Each plot corresponds to one day. Each trace represents the same minute at every hour on that day. Time scale is in seconds. (Image: Jordi Dيaz, ICTJA-CSIC)

A schematic summary of the effect of the convergence rate. Upper image shows a slow convergence rate allows thermal difussion and a derived reduction of slab's density (positive buoyancy). Lower image shows how a faster convergence rate increases the slab's density promoting the negative buoyancy. Credit: Kittiphon Boonma, Scientific Reports
