With an incredible duration of 1,774 days, the Mauna Ulu eruption of Kilauea Volcano in Hawaii spread across five years. At the time, it was Kilauea’s longest running eruption and produced about 460 million cubic yards of lava. From 1969 to 1974, the astonishing eruption was readily viewable to the public via observation platforms, and produced some incredible natural phenomena rarely seen during these volcanic events.
The US Geological Survey recently posted an image taken in 1969 by photographer J.B. Judd, which shows a rare dome fountain. Measuring about 65 feet (20 meters) high, the symmetrical dome fountain was one of twelve fountaining events that occurred during the first year of the eruption. The outward spread of lava during the fountaining events was so heavy that it spilled into the ocean 7.5 miles away.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
