Earthquakes and Thurston's boundary for the Teichmüller space of the universal hyperbolic solenoidAbstract: A measured laminations on the universal hyperbolic solenoid $\S$ is, by our definition, a leafwise measured lamination with appropriate continuity for the transverse variations. An earthquakes on theuniversal hyperbolic solenoid $\S$ is uniquely determined by a measured lamination on $\S$; it is a leafwise earthquake with the leafwise earthquake measure equal to the leafwise measured lamination. Leafwise earthquakes fit together to produce a new hyperbolic metric on $\S$ which is transversely continuous and we show that any two hyperbolic metrics on $\S$ are connected by an earthquake. We also establish the space of projective measured lamination $PML(\S)$ as a natural Thurston-type boundary to the Teichm\"uller space $T(\S)$ of the universal hyperbolic solenoid $\S$. The (baseleaf preserving) mapping class group $MCG_{BLP}(\S)$ acts continuously on the closure $T(\S)\cup PML(\S)$ of $T(\S)$. Moreover, the set of transversely locally constant measured laminations on $\S$ is dense in $ML(\S)$.
