Because of the way Google Earth work, volcanoes are almost always amazing to view inside of it. 3D terrain combined with high-resolution imagery makes for some stunning views, as we explained a while back in our “A to Z” post about Volcanoes.
The NASA Earth Observatory recently posted an image and article about “lava flows”, seen here:
From their article:
Streams of molten rock that ooze from gaps or vents in the Earth’s surface are called lava flows, and they can pose a hazard to everything in their paths. These rivers of rock can take many shapes and move at very different rates depending on the viscosity of the magma, the slope of the land, and the rate of an eruption.
While viscous lava flows are defined by steep flow fronts and pressure ridges, low-viscosity lavas tend to move faster and create longer, narrower shapes. They also tend to have smaller flow fronts and levee-like structure along their edges. Many characteristics of a low-viscosity lava flow are visible in this image of Zhupanovsky and Dzenzursky volcanoes on Russia’s Kamchatka Peninsula. The image was acquired by the Operational Land Imager (OLI) on the Landsat 8 satellite on September 9, 2013.
