Query: Earthquakes and Thurston's boundary for the Teichm\"uller space of the
  universal hyperbolic solenoid   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 $ML(\S)$.
