The parabolic Anderson model is the Cauchy problem for the heat equation on the integer lattice with a random potential ξ. We consider the case when {ξ(z) : z ∈ Z d } is a collection of independent identically distributed random variables with Weibull distribution with parameter 0 < γ < 2, and we assume that the solution is initially localised in the origin. We prove that, as time goes to infinity, the solution completely localises at just one point with high probability, and we identify the asymptotic behaviour of the localisation site. We also show that the intervals between the times when the solution relocalises from one site to another increase linearly over time, a phenomenon known as ageing.
