Data associated with 'Real-time prediction of rain-triggered lahars: incorporating seasonality and catchment recovery'

The rainfall and rain-triggered lahar record of the Belham River Valley, Montserrat between April 2010 and April 2012. The rainfall record comprises 0.1 mm resolution hourly precipitation data recorded at the Montserrat Volcano Observatory helipad gauge between Feb 2010 and Feb 2011, the St. George's Hill gauge between March 2011 and May 2011, and the maximum of the St. George's Hill and Windy Hill gauges between May 2011 and Feb 2012. The lahar database is compiled from visual inspection of seismic records and visual observations, and lahars are categorised based on magnitude (small, medium or large). Lahar signals were cross referenced to visual observations and carefully excluded from signals associated with primary volcanic activity and other seismic noise (such as construction vehicles).
