The Burridge-Knopoff model is a system of differential equations used to model earthquakes using
points on a straight line, each of mass , that interact with each other via springs, and in which all
masses are subject to a force that is proportional to the distances of the masses from their equilibrium position and to
a friction force ,
where
is the velocity,
