Specific geochemical precursors precede a repeated Lake Toba super eruption
the verdict
SUPPORTED
the evidence backs this
confidence 87/100
Geochemical and isotopic analyses of minerals and magma reservoirs indicate that specific precursors, such as volatile influxes and the assimilation of altered roof material, precede Lake Toba super-eruptions.
