There have been 108 earthquakes over 5.0 magnitude in the last 30 days, and now a 7.9 magnitude earthquake has struck Alaska, 75 miles south of Fairbanks. Scientists are struggling to understand how to predict quakes in time to provide effective warning, but so far they have only managed to get a few minutes' notice. They don't know why quakes seem to come in clusters or if an earthquake in one area will set off a quake somewhere else. Even the idea of earthquake clusters is controversial, because too little is know about how deep areas of the planet function to be certain if there even can be a connection between quakes in different parts of the world.
The Alaska earthquake struck Sunday afternoon, and could be felt throughout the state. There was much destruction, but there were none of the injuries that would have been expected if it had occurred in a more populated area or happened during the tourist season. It did cause major cracks in highways, including one 2 feet wide and 5 feet deep. Books seemed to jump off shelves and there were plenty of broken dishes.
It didn?t damage the trans-Alaska oil pipeline, which is designed to sustain a magnitude 8.5 quake. The oil pipeline crosses the Denali fault, where the earthquake happened. Geologist Kerry Sieh says engineers built the pipeline in a "zig-zag" pattern across the fault so that, in case of an earthquake, so it "would undo like an accordion, rather than break."
In 1964, an 8.4 magnitude earthquake struck Prince William Sound, about 75 miles east of Anchorage. The quake caused 115 deaths, most of them due to the resulting tsunami waves. It was the largest earthquake in North America and the second largest ever recorded. At 7.9, the current Alaska quake is not a record breaker, but was very, very strong.
