What recent eruptions reveal about persistent volcano misconceptions

A new review examines 18 common misunderstandings and uses seven recent volcano events to explain the hazards more clearly.

Editorial illustration — not from the study.

The authors group the misconceptions into six themes: seismology; volcanoes and climate; volcanic systems and structures; hazards; timescales; and photographs and footage. Each discussion includes key takeaways and summaries of recent research intended to help explain volcanic processes, hazards, impacts and risks.

The paper then presents case studies from Mount Agung in Indonesia, Mount Etna in Italy, Kīlauea in the United States, Tajogaite in Spain, La Soufrière in St. Vincent, Taal Volcano in the Philippines and Yellowstone caldera in the United States. These examples show how inaccurate information was shared and how it was countered.

The misconceptions examined

The researchers identify 18 misconceptions commonly encountered by volcanologists working with the public and media. They organize them into six themes, including misunderstandings about the “Pacific Ring of Fire,” “supervolcanoes,” “mega-tsunamis,” eruption forecasts, volcanic ash versus smoke, and magma “chambers.”

The paper also describes seven recent eruption or volcano case studies in which incorrect information was widely shared and then countered. The authors provide takeaway points and research summaries for each misconception to support clearer public explanations.

Why clear explanations matter

Volcanic information can spread rapidly during an eruption, but the paper notes that rumors can spread just as quickly. Correcting basic misunderstandings can help volcanologists and non-specialists communicate more accurately about what volcanoes do, how hazards develop, and the difference between hazards, impacts and risks.

Evidence and limits

This is a review and communication-focused article, not a report of a new experiment or a single observational study. Its evidence consists of summaries of recent research, explanations of 18 misconceptions and seven case studies drawn from public and media discussions around named volcanoes. The abstract does not provide quantitative measurements of how widespread the misconceptions were, how effective the corrections proved to be, or whether the communication approaches changed public behavior.

Thunderstorms reveal weak zones beneath an urban area

Researchers used seismic signals produced when thunder’s sound waves enter the ground to image the shallow subsurface beneath an urban karst setting. The method identified several previously undetected weak zones, some of which matched surface deformation and independent underground surveys.

Amazon droughts intensify wildfire pollution and estimated health risks

Amazon droughts were linked to stronger wildfire pollution during the dry season, according to a study covering 2010 to 2015. The researchers estimate that fire-related exposure to fine particles and ozone raised premature mortality more in drought years than in other years.

Arsenic and mercury risks varied sharply across Iranian cereal products

A study of 13 cereal-based products from Arak, Iran, found that estimated health risks varied widely between brands. Mercury drove the highest risk estimate for Tak pasta, while arsenic was the main factor for Zhik pasta; Zar, Mak and Jahan had much lower estimates.
