“Fingerprinting” Volcanic Tremors May Help Forecast Eruptions
Volcano seismic waves produce distinct tremor patterns, or "fingerprints," shared by different kinds of volcanoes.

Volcanic tremors can mean that an eruption is imminent, or maybe not. When it comes to linking tremors with impending eruptions, researchers are still very much in the dark. In a new study, however, one team of volcanologists revealed the existence of distinct tremor patterns, or tremor “fingerprints,” as they call them, shared among different kinds of volcanoes. Observations of such fingerprints may provide a small advance toward improved eruption forecasting: If, in the future, a volcano produces a fingerprint already found to have preceded or accompanied other eruptions, volcanologists might be better able to say whether an eruption will occur.
