The Krafla Fires — Screaming Voices from Beneath the Earth

Krafla Volcano, North Iceland

When Krafla erupted in 1724, witnesses reported human shapes moving within the lava flow and voices screaming from below the ground — not the sound of volcanic gas, but something that stopped when you spoke to it.

The Krafla volcanic system in North Iceland entered a period of intense activity in 1724 that lasted — with pauses — until 1729, a period known as the Mývatn Fires. The eruptions reshaped the landscape around Lake Mývatn dramatically, burying farmland under lava and forcing the evacuation of the surrounding district. The documentary record from the Mývatn Fires includes, alongside the practical accounts of crop loss and livestock death, a cluster of witness reports that the authorities of the time did not know what to do with and therefore left largely intact. Farmers watching the lava advance from high ground reported seeing human-proportioned shapes moving within the flow. Not above it — within it. The shapes moved at the speed of the flow, not against it. They were not described as struggling. Witnesses who described them consistently said the shapes were oriented in the direction of travel, as if being carried somewhere intentionally. Separately: in the weeks after the main eruptions, workers clearing debris from the margins of the lava flow reported hearing voices from beneath the ground. These were not the sounds of volcanic gas — which is hissing, uniform, and continuous. The sounds described were intermittent, variable in pitch, and ceased when the listener addressed them directly. Then resumed after a silence. Lutheran Iceland in 1724 had a theological category for this: the unquiet dead displaced by catastrophe, seeking acknowledgement before they could proceed. A minister was sent to the site. He performed a rite. The sounds were not reported after that. The Krafla system remains active. The next eruption is considered probable within decades.
