Hawaii hotspot
Hawaiian volcanoes are characterized by frequent rift eruptions, their large size (thousands of cubic kilometers in volume), and their rough, decentralized shape. Rift zones are a prominent feature on these volcanoes, and account for their seemingly random volcanic structure. The tallest mountain in the Hawaii chain, Mauna Kea, rises above mean sea level. Measured from its base on the seafloor, it is the world's tallest mountain, at ; Mount Everest rises above sea level. Hawaii is surrounded by a myriad of seamounts; however, they were found to be unconnected to the hotspot and its volcanism. Kīlauea has erupted continuously since 1983 through Puʻu ʻŌʻō, a minor volcanic cone, which has become an attraction for volcanologists and tourists alike.
Upolu Point
Upolu Point is the most northern point on the island of Hawaii in the Hawaiian Islands. It is an extruding landform created by cooled lava from an old eruption from Kohala volcano. The main town on the extrusion is Hawi, Hawaii about 2 miles (3 km) inland. The main road is Akoni Pule Highway t(Hawaii state route 270) which starts at the Hawaii Belt Road in Kawaihae, along the west coast of the point, and then through the towns of Hawi and Kapaau, ending at Pololū Valley. Upolu Point also overlooks Mahukona Harbor.
