Microscopic Volcanic Crystals May Provide Insights Prior to Eruptions

Buzzline

Researchers have identified a common chemical signature in minute plagioclase crystals located in volcanic rocks throughout the Pacific Ring of Fire. This study indicates that these tiny minerals can retain records of elevated magma entering subterranean reservoirs, paving the way for a deeper understanding of the dynamics underlying volcanic activity. Learn how this discovery could eventually assist scientists in pinpointing volcanoes that warrant increased observation, and why it does not currently facilitate accurate eruption forecasts.

00:00Tiny crystals hidden inside volcanic rocks may reveal clues to an approaching eruption.

00:05Scientists have discovered a chemical signature in microscopic minerals

00:09found across volcanoes along the Pacific Ring of Fire.

00:13The mineral is called plagioclase, and it grows inside underground magma.

00:18Researchers examined volcanic rocks from seven volcanoes across the central Andes

00:23using powerful microscopes and chemical analysis.

00:26They found that the smallest crystals share a remarkably similar chemical signature.

00:31This signature points to hotter magma rising from deeper underground

00:35and entering cooler magma reservoirs.

00:38That process can destabilize the underground system and help trigger an eruption.

00:42The discovery could eventually help scientists identify seemingly quiet volcanoes

00:47that deserve closer monitoring.

00:49But there is an important limitation.

00:51These crystals cannot tell scientists exactly when an eruption will happen.

00:56Instead, they offer a new way to read the hidden history of volcanoes

01:00and better understand the conditions that lead to eruptions.

01:03Disclosure.
