Ester Quakes


Alaska sits on a pretty fascinating part of the globe geologically speaking. We sit at the northern extent of the Ring of Fire which tectonically speaking provides the state with volcanic activity and earthquakes. If you've been paying attention to Alaska's local news over the last few months you would have noticed Mount Redoubt's series of rumblings and volcanic eruptions southwest of Anchorage. It's not uncommon for earthquakes to be felt somewhere in the state once or twice a year either. Normally it does not make the news unless it's rather large. About a week ago Becky and I were shaken awake around 5am by a 3 something tremor. It was short and not to bad so we thought nothing of it. It's a pretty fascinating thing to feel every once in a while. Over the next week we felt another six moderate tremors (maybe it was 5 or 7, I've lost count). A tremor once or twice a year is par for the course but to feel one almost every day for a week is unusual for around here. I just happen to work with a few inquisitive GIS savvy geologist that also happen to be our neighbors. They were aware the epicenters for the quakes were within miles of Fairbanks so they got the data from their sources and plotted it on a satellite image. The image above is the result.......It's our neighborhood. We live on the small kink in the road directly below the two largest yellow dots. Most of the tremors have been large enough to feel but all have been too small to cause damage. Mother Earth never fails to amaze. (I have not ruled out the notion that one of my neighbors is in cahoots with North Korea and top secret nuclear testing is taking place just down the street from us).
