Excerpt:On September 16, 2023, an unusual seismic signal shook the world. It appeared like clockwork every 90 seconds and lasted for 9 consecutive days.
A month later, a similar signal reappeared and lasted for another week before disappearing.
Scientists have since determined that these seismic anomalies were triggered by 2 massive landslides which ripped through a remote fjord in east Greenland. The rock-ice avalanche generated mega-tsunamis which reached 200m high at points and even damaged an empty military base.
Researchers believed these massive waves triggered a “seiche” (pronounced saish) or standing wave, which sloshed back and forth within the ford beating on either side like a drum to produce the very long signals.
But a Danish military vessel surveying the Dickson fjord just 3 days into the first seismic event never saw such a wave. In fact, until now the only evidence came from analytical and numerical models.
