Maarten de Moor would like to clear up a few things about the dramatic, weeks-long eruption of Hawaii’s Kilauea volcano.

Kilauea’s spectacular explosions won’t set off earthquakes on America’s West Coast. They won’t cause a tsunami, either. They won’t trigger a bigger, more catastrophic eruption like the one of Mount Pinatubo, in the Philippines, in 1991. “Not gonna happen,” de Moor, a volcanologist, said. And even though Kilauea is emitting lots of carbon dioxide, it won’t worsen global warming to any meaningful degree. “That one,” he said, “is just not based on any facts at all.”

Each of these myths about Kilauea have spread on the internet in one form or another since the volcano began spewing lava on May 3. They’ve been largely debunked thanks to scientists like de Moor, who monitors volcanic emissions for the Deep Carbon Observatory and the Volcanological and Seismological Observatory of Costa Rica. The Associated Press, for example, corrected its May 13 story that wrongly stated that Kilauea was part of the “Ring of Fire,” a belt of severe seismic activity that surrounds the Pacific Ocean. The popular-science publications Earther and National Geographic have also published extensive articles refuting most of these claims.

But one of these myths has been especially persistent.

“I would say they are all equally egregious, because in all cases we have scientific data and observations that refutes them,” said volcanologist Simon Carn, as associate professor at Michigan Tech. “However, the climate change myth is most persistent as it comes up after every significant eruption.”
