That's an interesting theory and it might make sense if it were at least occasionally reliable.
However, six volcanologists along with three tourists lost their lives in 1993 when they ignored a series of earthquakes while exploring another currently active volcano, the Galeras Volcano in Colombia.
"Galeras volcano erupted in 1993 and killing 6 scientists and 3 tourists.
Tornillo earthquakes were measured prior to the 1993 Galeras eruption but they were not recognized by scientists as eruption precursors." John Seach Volcanologist
