Earthquake South of Diomede, No Injuries Reported
A magnitude 5.0 earthquake struck about 20 miles south of Little Diomede on February 3, 2025, with residents in the region feeling the tremor but reporting no injuries. Seismic events along the Bering microplate have happened before, although they’re not common. The largest on record was a magnitude 7.3 earthquake near Huslia in 1958.

Polar bear with cub visits Diomede School
John Ahkvaluk , 56, a polar bear guard revealed that this is not a good sign for the village. It’s the first time in several years that bears come at this time of the year. “It’s a warning that they got no food out there and they came looking for it here,” he said.
After the incident, Luchie Manlangit, the school principal, and I invited John Ahkvaluk to talk to the kids and to share some protocols if polar bear will come around again.

Russian tanker passes through Bering Strait in the midst of winter
Last week, a 908-foot Russian tanker carrying liquified natural gas passed south through the Russian side of the Bering Strait, with two more to follow. The ships are traversing the northern coast of Siberia, called the North Sea Route, in the middle of January with no icebreaker escort, an unprecedented event that may hint at the future of the region as climate change alters global commerce.

Wales lost shorefast ice early in the season. Ice along the shore has been crushed and broken. This is a very unusual event for Wales as many of our hunters rely on great ice conditions for whale and other sea mammal catch for food.

NOAA survey shows shocking lack of thermal barrier between northern and southern Bering Sea
The “thermal curtain” is another expression for “cold pool” that acts as a barrier to keep some species—pollock and Pacific cod, for example — from migrating across the eastern Bering Sea shelf and northward toward the Bering Strait. For the first time in 37 years of surveying the Bering Sea, we could not find the cold water barrier.

No Sea Ice Yet
By this time of the year, we usually have 2-3 miles of shore-fast ice that sticks to our beach. We as a village have not done our winter harvest of seals and walrus, and we are worried that we will not be able to bowhead whale hunt.
