In an unprecedented event that unfolded quietly yet dramatically along Greenland's east coast, a colossal mega tsunami, towering at 650 feet, emerged near a popular cruise ship route last year.
This extraordinary occurrence went unnoticed in real-time, but the relentless pursuit of scientific inquiry has since unveiled its mysteries. The phenomenon came to light through the detection of seismic waves reverberating over a span of nine consecutive days in September, presenting a puzzle to the scientific community.
Kristian Svennevig, a geologist with the Geological Survey of Denmark and Greenland, took on the challenge of deciphering these signals. Unlike typical earthquake tremors, these waves featured a distinctive oscillating pattern with 92-second intervals between peaks and persisted with remarkable strength for an extended period.
The source of this unusual seismic activity was eventually traced back to eastern Greenland. Here, satellite and ground-based observations revealed that an immense section of mountaintop—soaring nearly 4,000 feet above Dickson Fjord within the expanse of Northeast Greenland National Park—had catastrophically collapsed.
Scientists deduced that the glacier nestled at the mountain's base had succumbed to melting, unleashing a staggering volume of rock and ice into the fjord below—equivalent to the contents of 10,000 Olympic-sized swimming pools. On September 16th, this massive displacement generated a wave reaching heights equivalent to a 65-story building.
What ensued in the narrow confines of Dickson Fjord was not merely a transient wave but rather a persistent oscillation known as a seiche. This phenomenon saw the colossal wave ricochet back and forth within the fjord's boundaries—an observation mirrored by the unique seismic signature that had initially puzzled researchers.
Stephen Hicks, a seismologist at University College London observed, "We've never witnessed such an extensive movement of water persisting for such duration."This mystery was unraveled through concerted efforts spanning disciplines and borders alike—a testament to collaborative scientific endeavor. According to Svennevig, lead author of the groundbreaking study published in Science magazine involving 68 scientists from 41 different research institutions worldwide. This multidisciplinary approach underscored climate change's integral role in triggering such catastrophic natural events by melting glaciers—a harrowing reminder that further erosion of polar ice could precipitate more devastating landslides.
Fortunately, there were no human casualties from this monumental tsunami; however, it wreaked havoc on infrastructure valued at approximately $200,000 at an Ella Island research station. This incident serves as both a marvel and warning—highlighting nature’s formidable power unleashed as unintended consequences of climate change become increasingly apparent across our planet’s most remote landscapes.
