Center of Hot Spot 0.004 Loihi The Hawaiian Islands are the result of the Pacific Plate moving over a "hot spot" in the Pacific Ocean. The hot spot is assumed to be stationary within the mantle. Since the southeastern portion of the Big Island of Hawaii still has active volcanoes, and Loihi (a submerged volcano located southeast of the Big Island) is active, let's assume the center of the hot spot is located as shown on the map above. Table 1 below gives the names of the volcanoes associated with their age (in millions of years) in the map above. 1. Using the map scale, measure the distance to each of the volcanoes from the center of the hot spot and record your results in column three of the table. Table 1. 1. Volcano 2. Age in millions of 3.
