Red and blue waves triggered by a magnitude 4.6 earthquake rippled outward from the Anchorage area and fizzled out after 45 seconds. Except in Cook Inlet basin, where the waves were trapped for another half-minute, bouncing back and forth, up and down, within the 7.5-kilometer-thick sedimentary basin.

“It’s like throwing a rock in the pond. Except water is a homogeneous material. In the solid earth you have basins and mountains and other variations,” said Carl Tape, a seismologist and assistant professor at the University of Alaska Fairbanks.
Science Potpourri celebrates 20 years of fun and science
Lester’s Forbidden Experiment. Screaming Gummy Bears. Blowtorch in a Beaker. The three are among a host of activities on the roster for the University of Alaska Fairbanks’ 20th annual Science Potpourri Saturday, April 13 from noon to 3 p.m. The College of Natural Science and Mathematics hosts the free event, which will be in the Reichardt Building on the UAF campus.

Around midnight on January 4, Kathleen Brandt felt an earthquake at her home in Sitka. As framed pictures trembled and then fell from the walls, she started counting.
Southeast residents show savvy after large earthquake
Natalia Ruppert spoke to about 170 people in both Sitka, pictured here, and Craig. After her presentations, a few people shared their earthquake experiences and told of moving to high ground to escape a possible tsunami.

Seismologist visits Southeast in wake of large earthquake
Seismologist Natalia Ruppert prepares to fly from Ketchikan to Thorne Bay in a DeHavilland Beaver floatplane. The Fairbanks seismologist traveled to small communities in Southeast Alaska in response to a large earthquake in the area a few weeks prior.

CRAIG — In this cozy Southeast Alaska community that smells of red cedar chips used to power a boiler that heats both the school and the pool, seismologist Natalia Ruppert responded to an hour of questions from more than 150 people who gathered in the auditorium of the Craig High School.

Science for Alaska 2013
Mark your calendars for Science for Alaska 2013! Our 21st year of the popular lecture series will experience some changes. Lectures will take place in Schaible Auditorium on the UAF campus and occur on Saturdays throughout January. We're hoping the smaller space and the coffee to follow each of the lectures will lead to a more intimate exchange between our line-up of lecturers and the community.
