A remote_control landslide produce a tsunami stopping_point calendar_month at Kenai Fjords National Park near Seward . No injury or fatality were report , but the wave cause child damage to a privately - own boardwalk . harmonize to the National Park Service , the Aug. 7 landslide sprinkle down into the upper_berth part of Pedersen Lagoon about 20 mile southwest of Seward , produce a wave about 55 foot high . Then it traverse over a ridge and flow into the lower_berth part of the lagoon , hit the shore at a height of about 3 foot . Chad Hults , the Park Services regional geologist for Alaska , state the slope above the water is unstable . As a consequence , the landslide and tsunami did nt semen as a surprise . The landslide give manner during a very significant rain event that happen that week , I believe it was around 15 inch of rain that hide that week , Hults state . Hults state the region has see several landslide within the stopping_point few old_age , and that heavy rain and cutting glacier are devising them more park . people should be careful about travel and understand when there second heavy rain event , those are times when landslide can be trip , and they can hit the water and generate tsunami , he state . The Park Service recommend visitor to Pedersen Lagoon return precaution for the possibility of other landslide or tsunamis.
polar icecap thaw has been towards the top of the concern list of the climate - conscious for old_age . ocean degree have rise an inch and a one-half ( 3.8 centimeter ) in the stopping_point decade alone as ten of million of gallon of fresh_water thaw into the ocean each year . scientist have recently warn that thaw might be just one of our concern as megatsunami wave can give 330 - foot - plus ( 100 - meter - plus ) rise to the ocean in a matter of minutes . tsunami are massive wave cause by the sudden supplanting of water from landslide , vent , earthquake , etc . They can range speed over 500 miles_per_hour ( 800 kilometer / hydrogen ) and travel across stallion ocean before reach land and causing unprecedented destruction and implosion_therapy to anything in their way . Megatsunamis are especially large tsunami , generally trip by huge ball of fall ice , rock , or soil into the ocean causing massive wave . Unlike convention wave that are on the surface and cause by wind , tsunami are hanker wave_form that affect the stallion ocean , from the surface to the sea floor as they travel along their destructive way . With global temperature on the rise , glacier are thaw and receding , expose unstable mud and rock below . And with the Earth 's tectonic home_plate ever - shift , topographic_point like Greenland are experience considerable megatsunamis as huge ball of ice and Earth interruption away and fall into the ocean from the steep coastal cliffs.
On September 16 , 2023 , a mass of rock the size of a football stadium suddenly interrupt away from about 200 foot ( 60 meter ) up , transport debris and glacial ice over 1,000 foot ( 300 meter ) down the 40 slope before crash into the ocean causing a splash over 650 foot ( 200 meter ) high before turn into a roughly 200 - foot ( 60 - meter ) tall wave 6.2 mile wide ( 10 kilometer ) within the Dickson Fjord in eastern Greenland . The wave splash back and forth for over a week . seismology equipment 3,106 mile ( 5,000 kilometer ) away felt the event as well as the aftereffect of the splash seiche for a week . tsunami early warning system have make an impact in economy life . company have even travel so far as to physique floating tsunami survival pod and " tsunami - proof " house . Even Army_Intelligence hour_angle some skin in the game with rogue wave detection ... which technically are n't tsunami , but the technology is there . Army_Intelligence has also been use to predict flood way from these powerful waves.
