  • New research estimates probability of mega-earthquake in the Aleutians

    A team of researchers from the University of Hawai'i at Mānoa (UHM) published a study this week that estimated the probability of a Magnitude 9+ earthquake in the Aleutian Islands--an event with sufficient power to create a mega-tsunami especially threatening to Hawai'i. In the next 50 years, they report, there is a 9% chance of such an event. An earlier State of Hawai'i report has estimated the damage from such an event would be nearly $40 billion, with more than 300,000 people affected. Earth's crust is composed of numerous rocky plates. An earthquake occurs when two sections of crust suddenly...

    A powerful earthquake in Alaska sent towering waves up to 30 feet (9 meters) tall crashing down on Hawaii about 500 years ago, leaving behind fragments of coral, mollusk shells and coarse beach sand in a sinkhole located on the island of Kauai, new research finds. The quake, likely a magnitude 9.0, sent the mighty waves toward Hawaii sometime between 1425 and 1665, the study found. It's possible that another large Alaskan earthquake could trigger a comparable tsunami on Hawaii's shores in the future, experts said. The tsunami was at least three times the size of the damaging 1946 tsunami,...

    Semisopochnoi Island, from space, from sea level This image came up a few days ago in the Earth Observatory. Clicking it here will go to the full image from space, which isn't labeled. I wondered if they were any images of the Semisopochnoi volcanoes from sea/ground level or aircraft. There are. Below are two pictures of the Fuji-esque Sugarloaf Peak. Second is clickable, first isn't.

  • Alaska's Rat Island apparently rid of its namesake pest

    Yahoo News ^ | Mon Aug 24, 6:00 am ET | Erika Bolstad
    WASHINGTON — After two centuries of an epic infestation, Alaska's Rat Island finally may merit a name change. The island, part of a national wildlife refuge in the sprawling Aleutian chain, appears to be pest-free for the first time since rats overran it after a Japanese sailing ship wrecked there in the late 1700s. Scientists stopped by in early August to check on the progress of the $3 million eradication. So far, "no sign of rats whatsoever," said Steve MacLean , the polar marine program director for The Nature Conservancy in Alaska , one of the partners in the rat-ridding...

Shawn Dahle, and the National Oceanic and Atmospheric Administration, National Marine Mammal Lab August 2: Janet Schaefer, Alaska Volcano Observatory / Alaska Division of Geological & Geophysical Surveys. August 3: Jessica Larsen, Alaska Volcano Observatory / University of Alaska Fairbanks, Geophysical Institute. Something completely different; one of my books has a picture of the largest crystal of "burmite", Burmese transparent amber, in the word. I hunted around and found an Internet picture of it. It's in the UK Natural History Museum,...

  • CA: Hungry geese a peck of trouble for Humboldt Bay ranchers

    EUREKA, Calif. (AP) - Honk if you're glad the geese are gone. Humboldt Bay ranchers are overjoyed that hungry hordes of the messy fowl are finally on their way north to nest. Ravenous Aleutian cackling geese have been eating up their pasture. The Aleutian geese, once an endangered species, now number at least 60,000 and many like to feast on the sweet spring grasses of the Humboldt Bay bottomlands. They'll nest in the wind-chilled Aleutian Islands - then eventually head back to the land of the worried ranchers to fortify themselves again. A survey last month found 10,000 of the...
