  abstract = {{B}oth laboratory experiments and dynamic simulations suggest that earthquakes can be preceded by a precursory phase of slow slip. {O}bserving processes leading to an acceleration or spreading of slow slip along faults is therefore key to understand the dynamics potentially leading to seismic ruptures. {H}ere, we use continuous {GPS} measurements of the ground displacement to image the daily slip along the fault beneath {V}ancouver {I}sland during a slow slip event in 2013. {W}e image the coalescence of three originally distinct slow slip fronts merging together. {W}e show that during coalescence phases lasting for 2 to 5 days, the rate of energy (moment) release significantly increases. {T}his observation supports the view proposed by theoretical and experimental studies that the coalescence of slow slip fronts is a possible mechanism for initiating earthquakes. {S}low slip events are commonly observed on natural faults all around the world and are suggested to precede large magnitude and/or high frequency earthquakes. {T}he authors here identify merging phases of slow slip events using continuous {GPS} measurements and define areas and periods at risk of large earthquake occurrence.},
