With the massive eruption at Bogoslov Volcano in the Aleutian chain near Alaska, air travel was restricted and still remains “hazardous”. Something similar happened in 2010 when air travel was restricted over Europe and an Icelandic volcano erupted. Now Steam vents are opening through the Greenland ice sheet and Katla is on yellow elevated warning with over 500 small quakes with a 50-50 chance of an eruption. This uptick in volcanic activity was predicted to go hand in hand with the intensification of the grand solar minimum. Here we go, ramp up from here.
Iceland Could Be About To Experience A Major Volcanic Eruption ..
Mathematical models developed by the USGS, UAF, and NOAA forecast various aspects of how a volcanic ash plume will interact with wind—where, how high, and how fast ash particles will be transported in the atmosphere, as well as where ash will fall out and accumulate on the ground. AVO runs these models when a volcano is restless by assuming a reasonable hypothetical eruption, in order to provide a pre-eruptive forecast of areas likely to be affected. During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available. All models use the same input parameters so they are comparable.
