A new explosive eruption occurred at Bogoslof volcano that lasted for about 30 minutes and produced a cloud that rose as high as 20,000 ft and drifted northeast as seen in satellite images. Last night’s event was first detected by seismic stations on neighboring Umnak Island, and was also seen in more distant infrasound sensors.
As a result of the recent pattern of Bogoslof, the likelihood of continued eruptions remains high keeping the Aviation code at RED and Volcano Alert Level at WARNING. The explosive event was preceded by 4 ½ hours of elevated seismic activity from Bogoslof, providing some indication an explosive eruption was imminent. Other explosions during the eruptive sequence have started more suddenly with either subtle or no preceding increase in seismicity.
Because a local geophysical network does not monitor Bogoslof, the Alaska Volcano Observatory (AVO) is using seismic and infrasound (airwave sensors) on neighboring Umnak and Unalaska Islands to monitor activity. In addition, we are using satellite imagery and information from the Worldwide Lightning Location Network to identify volcanic lightning; lightning strikes in the erupted plume have been detected during the current eruptive sequence.
As a result of natural disasters occurring more often (no surprise for us paying attention), I find myself engaged in the onsite events more often, and less available to maintain my alternative ventures keeping SOC healthy. But thanks to my wife’s exorbitant creative thinking, I believe we found a way to stay on top.
Between now and January 1st 2017, by donating $10 you will be grandfathered into a full one year membership. Beginning January 1st 2017, we will be going back to our annual memberships starting at $34.95 per year. Yes, this is to say with just $10 you will have a full membership for the next full year of 2017.
For those of you who can do a bit more, we graciously appreciate when you can provide larger amounts – it truly goes a long way in keeping us alive and well.
Go to the following link which takes you to a page. On the right side of our home page under where it says “Science of Cycles Community Support” you will find a drop-down menu to choose your amount. Beginning next year we will have other methods for you to purchase a membership, for now please use PayPal. Remember, you do not have to join PayPal to use it. Just look for the tap that says Pay with Debit or Credit Card. No sign-up is necessary. Click Here
I have more breaking news I am sitting on right now, and will be posing and sending out over the holidays. Cheers, Mitch
