Never a Dull Moment on Planet Earth

There’s something about the way this eruption plume from Cleveland volcano is piercing the cloud deck that really caught my attention.

Rising 5,676 feet right up from the sea in the Aleutian Island chain, the volcano experienced an explosion at 5:00 AM local time on May 4, and then began erupting at a low level. The plume seen in this image is streaming to the east.

The image was captured by NASA’s Terra satellite. For another view, captured by the Suomi NPP satellite, check out this post at the Cooperative Institute for Meteorological Satellite Studies.

Here’s a beautiful photo of Cleveland shot from an airplane a couple of years ago:

Meanwhile, just a bit to the East:

A line of spiraling clouds called a Von Karman vortex street formed on May 4 downwind of the high terrain of the Aleutian Islands, just east of Cleveland volcano.  As with the top image, this one was captured by NASA’s Terra satellite. For an explanation of the phenomenon, along with a pretty cool animation showing how the vortices form and propagate, click here.
