Hawaii

The Big Island (officially named Hawaii) is the largest island in the United States. Within Volcanoes National Park, there are 2 active volcanoes, Kilauea and Mauna Loa. Covering 4,028 square miles, the Big Island (or the “Orchid Isle”) is the youngest and largest of the Hawaiian Islands — twice the size of all the other major Islands combined. And with two of the five volcanoes that created the island still active, it continues to grow: Kilauea Caldera is the longest continuously erupting volcano in the world, its present eruptive phase dating back to 1983; Mauna Loa, meanwhile, last erupted in March of 1984, sending lava to within a few miles of East Hawaii’s Hilo town. Of the remaining three volcanoes on the island, Mauna Kea and Kohala are extinct, while Hualalai is considered to be dormant, having last erupted in 1801.hough the average temperature on the Big Island ranges from 71 to 77 degrees Fahrenheit in the coastal regions (with temperatures in the low 70s October through April), the summits of Mauna Kea and Mauna Loa are often blanketed with snow. The population is 186,738 (2011).
