The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami. Those are […]
A study of two powerful earthquakes in adjacent areas of the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade along the fault. The research was published Wednesday in the journal Science Advances in a paper jointly led by University […]
Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research published this month. The finding, published April 2 in the journal Geosciences, discusses the distribution of hadrosaurids and ceratopsids — the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago. The work […]
Hydrogen and oxygen ions escaping from Earth’s upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical Institute scientists. The work led by UAF Geophysical Institute associate research professor Gunther Kletetschka adds to a growing body of research about […]
