New Delhi: Scientists have warned that the melting of Alaska glacier could prompt an uprecedented ‘mega-tsunami’. The researchers claimed that the catastrophic event may take place within the next 12 months if the melting glaciers trigger landslides.
According to scientists, if such an event does not take place within the next 12 months, then the mega tsunami is likely to occur within the next 20 years.
The researchers had warned about the potential disaster in May this year and also wrote an open letter to the Alaska Department of Natural Resources (ADNR) in this regard.
Scientists say they are worried about an area called Prince William Sound that falls along the south coast of Alaska in the United States. Prince William is a remote region but its surrounding water is frequented by boats and cruise ships.
The region has witnessed glacier retreat leading to instability on the slopes of a mountain in Barry Arm above the Barry Glacier.
In the open letter, the researchers wrote, “We, a group of scientists with expertise in climate change, landslides, and tsunami hazards, have identified an unstable mountain slope above the toe of Barry Glacier in Barry Arm, 60 miles east of Anchorage, that has the potential to fail and generate a tsunami. This tsunami could impact areas frequented by tourists, fishing vessels, and hunters (potentially hundreds of people at one time).”
The letter further said, “We believe that it is possible that this landslide-generated tsunami will happen within the next year, and likely within 20 years.” Images taken by satellites reveal that the melting of the glacier has left a large rocky area exposed.
The climate change experts also said that the slow movement of the landslide is already taking place but if large part of the mountain slope melts then it could have disastrous consequences.
