Geosonnet 69
An accidental drilling in the deeps
Reveals a sleeper agent- felsic melt
Invisible to seismic, magma sleeps
Until basaltic trigger card is dealt.
Diffraction limits fuzz the chamber’s sides
Viscosity impedes acoustic tests
A covert, dried out dacite simply hides
Above basaltic plumbing, long at rest.
Three hundred years, this hidden magma sleeps
Until it’s poked by hydrothermal drill.
Old pumice, cuttings from the drilled-out deeps
Show magma lurking, poised to blast and kill.
Basaltic dykes wake sleepers from their doze
Do not ignore the hazard this can pose!
