The time lag between intrusion of fresh, hot magma and an ensuing
eruption is of critical importance in both understanding the
triggering and mitigating the consequences of volcanic eruptions.
This work looks at material erupted during 1925-28 at the Nea
Kameni volcanic center in Santorini, Greece, to determine this
time scale. By exploiting Fe-Mg diffusion in olivine crystals,
we constrained the intrusion-to-eruption time lag to between
3 and 10 weeks. These techniques have potential application
at many volcanic centers; previously erupted material can be
used to calibrate records of the short-time scale processes
common to many volcanic centers.
