Seismic activity that accompanied the effusive and explosive eruptions during the 2004-2005 period at Volcán de Colima, Mexico

► Families identified from cross-correlation, stay during the whole period of activity and indicate repetitive sources. ► Occurrence of LP families identified as early warnings of vulcanian explosions. ► The use of the material failure forecasting method (FFM) in LP swarms, to obtain the approximate time of vulcanian explosions. ► Monochromatic LPs occurred during this period, some of them just some hours before an explosion.
