Earth shook every 90 seconds for 9 days in 2023; scientists finally reveal the shocking reason

In 2023, a mysterious 90-second seismic pulse baffled scientists worldwide, traced back to Greenland’s Dickson Fjord. Researchers now attribute these rhythmic tremors to massive glacier-induced avalanches triggering seiches, giant oscillating waves within the fjord. This discovery, enabled by advanced satellite technology, underscores the escalating impact of climate change in remote Arctic regions, causing geological events with global seismic consequences.
