Greenland Landslide: Unusual Global Seismic Signal and Climate Change Impact - Technology

unusual global seismic signal associate to Greenland Landslide

An extraordinary global seismic signal that last for nine days has been associate to a massive avalanche in eastern Greenland . The event , which take topographic_point stopping_point September , was cause by a landslide trip by glacial thaw due to Climate Change . The signal , know as the Unidentified Seismic Object ( USO ) , catch the attention of research_worker worldwide , with 68 expert from 15 state collaborate to investigate the phenomenon.

 The USO label is an informal term some seismologist use when they semen across a seismic signal they ca n't explain,

state Kristian Svennevig , the lead writer of the report particularization the unusual signal . initial analysis uncover that the signal was not the consequence of an earthquake but rather a alone happening cause by a massive avalanche in Greenland.

The avalanche that light-emitting_diode to the seismic signal involve the collapse of a mountaintop above the Dickson fjord , sending over 25 million cubic meter of rock and ice into the water . The volume of material displace was equivalent to filling 10,000 Olympic - size swimming pool , harmonize to the research_worker . The result tsunami reach a height of 200 meter ( 656 foot ) and make a phenomenon know as a seiche , where the water splash back and forth in the fjord.

 As scientist dig into the research , they detect that the seismic signal resonate for nine days as a consequence of the trap energy in the rocky fjord , causing the water to hover with a frequency of 11.45 millihertz.

The decelerate amplitude decay and frequency of the signal were nearly identical to the oscillation form detect in the seiche phenomena.

The research_worker warn that similar event could happen in the future due to the effects of climate change , with an increase frequency of landslide and tsunami expect in the Arctic region . The deduction of this event serve as a wakeup call to the scientific community and highlight the need for foster research into how the planet is adapt to change environmental conditions.

 Kristian Svennevig stress that the event supply valuable penetration into the impact of climate change on natural phenomenon and underscore the importance of ongoing research in this field.

The unprecedented nature of the global seismic signal serve as a reminder of the unpredictable consequence of climate change and the pressing need for proactive measure to extenuate its effects.
