A pyroclastic flow is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F). Pyroclastic flows normally hug the ground and travel downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. They are a common and devastating result of certain explosive volcanic eruptions.
Birgit Schlosser specializes in spare, clean architecture photography, and that aesthetic is also in play in Volcanic Dreamscapes, a new series of works depicting the beauty of sparse volcanic ecosystems.

Scientific American created this helpful explainer of how the chain of Hawai’ian Islands formed. The tectonic plate is moving northwest over a magma hot spot in the earth’s mantle. In fact, there’s a new Hawai’ian island named Loihi forming underwater right now.
The field of data analytics is growing as fast as the internet itself.

Even with the help of powerful software like Python, it’s a highly skilled position. But those skills […]

Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
