Andean Crystals Reveal a Possible Eruption Mechanism

In this lesson: Evaluate the limits of a proposed eruption clue.

Read the story

A study published on November 9 identified a recurring chemical signature in small plagioclase crystals from Andean volcanoes, Queensland researchers reported.

Modelling points to hotter, deeper magma disturbing a shallow reservoir. The pattern could guide future monitoring research, but it is not an established timetable for predicting eruptions.

Read and practise

1. Which use is presented as possible rather than established?

   1. Providing a reliable eruption timetable
   2. Identifying a chemical signature in the studied crystals
   3. Guiding future monitoring research

2. What evidence was observed directly in the study?

   1. A test of every oceanic volcano
   2. A recurring chemical signature in crystals
   3. A guaranteed date for the next eruption

Your turn

Explain why the finding is promising without claiming it predicts eruption dates.
