History. 1  A soldier carries an early example (1945) of mobile synchronous radio communication. 2  A basic chat box allows quick communication, but with too many people can be frustrating. 3  All those red flags are messages I've ignored, a pitfall of asynchronous communication.
Earth's Largest Volcano-Mauna Loa,Hawaii. The largest volcano in the world is Mauna Loa on the island of Hawaii. There have been references to Yellowstone as the largest volcanic system in North America, but most, if not all, scientific organizations recognize Mauna Loa as the largest single volcano.
Mauna Loa, meaning Long mountain in English, is the largest subaerial volcano in both mass and volume. It is one of the five volcanoes that form the Island of Hawaii in the Pacific ocean. Historically, Mauna Loa has been considered the largest volcano on the Earth. The volume of Mauna Loa is estimated at approx 18,000 cubic miles. It is an active shield volcano with its peak at the height of 120 feet which is lower than its neighbor Mauna Kea. The lava of Mauna Loa is tended to be non-explosive, silica-poor and very fluid.
