Answer 2

The island of Hawaii followed by Kodiak Island in Alaska

Answer 3

If land area is the criteria:

Greenland (belongs to Denmark, but is part of North America) at 840004 square miles.

Baffin Island (Canada, North America) at 195928 square miles.

Isla de Tierra del Fuego (Argentina and Chile, South America) at 18301 square miles.

And then measly little Hawaii (if, by America, you mean solely the United States) ... at 4071 square miles.

Answer 4

That would be Hawaii ( the island, not the whole state.) Kodiak Island, in southern Alaska, is the second largest.

Answer 5

Hawaii

Answer 6

The Island of Hawaiʻi (called the Big Island or Hawaiʻi proper) is one of eight main islands that make up the U.S. State of Hawaiʻi. It is said to have been named after Hawaiʻiloa, a legendary Polynesian navigator who first discovered the Hawaiian Islands. However, other accounts attribute the name to the legendary land or realm of Hawaiki, or Havaiki, a place from which the Polynesians originated (see also Manua), the place where they go in the afterlife, the realm of the gods. The Island of Hawaiʻi is larger than all the other Hawaiian Islands combined.

The Island of Hawaiʻi is administered under the County of Hawaiʻi. The county seat is Hilo. It is estimated that as of the year 2003, the island had a resident population of 158,400 persons.

Geology and geography
The Island of Hawaiʻi is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. These are (from oldest to youngest): Kohala (extinct), Mauna Kea (dormant), Hualālai (dormant), Mauna Loa (active, partly within Hawaiʻi Volcanoes National Park), and Kīlauea (very active; part of Hawaiʻi Volcanoes National Park). Interpretation of geological evidence from exposures of old surfaces on the south and west flanks of Mauna Loa led to the proposal that two ancient volcanic shields (named Ninole and Kulani) were all but buried by the younger Mauna Loa (MacDonald and Abbott, 1970). Geologists now consider these "outcrops" to be part of the earlier building of Mauna Loa.

In greatest dimension, the island is 93 miles (150 km) across and has a land area of 4,038 mi² (10,458 km²), representing 62% of the total land area of the Hawaiian Islands. Measured from its base at the sea floor, to its highest peak, Mauna Kea is the tallest mountain in the world, even taller than Mount Everest, according to the Guinness Book of Records. Traditionally, Hawaiʻi is known as the Big Island because it is the largest of the Hawaiian Islands and some confusion between Hawaiʻi Island and Hawaiʻi State can be avoided.

Because Mauna Loa and Kīlauea are active volcanoes, the island of Hawaiʻi is still growing. Between January 1983 and September 2002, 2.2 km² (543 ac) of land were added to the island by lava flows from Kīlauea volcano extending the coastline seaward. Several towns have been destroyed by Kīlauea lava flows in modern times: Kapoho (1960), Kalapana (1990), and Kaimū (1990).

Hawaiʻi is the southernmost island in the Hawaiian archipelago, and contains the southernmost point in the United States, (Ka Lae). The nearest landfall to the south would be in the Line Islands. To the north is the island of Maui, where East Maui Volcano (Haleakalā) is visible across the Alenuihāhā Channel (see photo at left).

18 miles (29 kilometers) off Hawaiʻi Island's southeast coast is the undersea volcano known as Lōʻihi. Lōʻihi is an actively erupting seamount that lies 3,200 feet (975 meters) below the surface of the ocean. It is thought that continued volcanic activity from Lōʻihi will cause the volcano to eventually breach sea level and later attach at the surface onto Kīlauea, adding even more land to Hawaiʻi's surface area. This "event" is presently predicted for a date several tens of thousands of years in the future. Hilina Slump or the Great Crack is an 8 mile long, 60 feet wide and 60 feet deep crack in the island, situated in the district of Kaʻū. The Great Crack is one of many series of cracks and rifts that was formed by eruptions and, in fact, is an extension of the southwest rift zone. Often these rifts are the sites of volcanic eruptions and occasionally a rift can be so deep and so fractured that it can cause a chunk of the island to fall into the ocean.

Some believe that the Great Crack is a result of the south flank of the Big Island moving away from the rest of the island. Speculation abounds that someday, perhaps soon, a major chunk of the island will break away and fall into the ocean, along with the resulting huge tsunami and earthquake. This actually does happen every ten thousand years or so, so it is not outside the realm of possibility. Others believe the Great Crack is not a fault that will break the island apart, but instead was created (probably thousands of years ago) as a result of the crust moving apart slightly due to magma forcing itself into the rift zones. The Great Crack has been measured and is tracked and there is no indication that it is enlarging in any way or that the island is shifting near this point. Furthermore, the walls of the crack have been shown to fit together perfectly, thus proving that the crack was a widening of once joined ground.

One can find trails, rock walls, and archaeological sites from as old as the 12th century around the Great Crack. Much of these finds are on the park side of the fence. About 1,951 acres of private land beyond the fence was purchased during the Clinton administration specifically to protect the various artifacts in this area as well as to protect the habitat of the turtles. However, near the end of the crack is an area of land between the fence, the crack and the ocean which is not part of the park land and does have many archaeological artifacts on it.

In 1823 a very fluid flow of lava came out of a 6 mile portion of the crack and made its way to the ocean.

On April 2, 1868, an earthquake in this area with a magnitude estimated between 7.25 and 7.75 on the Richter scale rocked the southeast coast of Hawaiʻi. It triggered a landslide on the slopes of Mauna Loa, five miles north of Pahala, killing 31 persons. A tsunami claimed 46 additional lives. The villages of Punaluʻu, Nīnole, Kawaʻa, Honuʻapo, and Keauhou Landing were severely damaged. According to one account, the tsunami "rolled in over the tops of the coconut trees, probably 60 feet high ... inland a distance of a quarter of a mile in some places, taking out to sea when it returned, houses, men, women, and almost everything movable." This was reported in the 1988 edition of Walter C. Dudley's book, "Tsunami!" (ISBN 0824811259).

On November 29, 1975, a 60 kilometer (37 mile) wide section of the Hilina Slump plunged 11 feet (3 m) into the ocean, widening the crack by 26 feet. This movement caused a 7.2 magnitude earthquake and a 15 meter (48 ft) high tsunami. Oceanfront properties were washed off their foundations in Punaluʻu. Two deaths were reported at Halapē, and 19 other persons were injured.

The northeast coast of the Big Island has also suffered tsunami damage from earthquakes that triggered waves from Chile and Alaska. Hilo was severely damaged in 1946 and 1960, with many lives lost. Laupāhoehoe alone lost 16 school children and 5 teachers in the 1946 tsunami.
