USS Arizonaâs entire band was lost in the attack. Almost half of the casualties at Pearl Harbor occurred on the naval battleship USS Arizona, which was hit four times by Japanese bombers and eventually sank. Among the 1,177 crewmen killed were all 21 members of the Arizonaâs band, known as U.S. Navy Band Unit (NBU) 22.
Are the three major plates that border the South American Plate. The Nazca Plate is subducting under the South American Plate. The boundary between the African Plate and the South American Plate is a divergent boundary. The South American Plate is moving at more than 15 cm/yr. 1. The center of the South American Plate is the city of Brazilla, in Brazil.
Plate-boundary zones Not all plate boundaries are as simple as the main types discussed above. In some regions, the boundaries are not well defined because the plate-movement deformation occurring there extends over a broad belt (called a plate-boundary zone). One of these zones marks the Mediterranean-Alpine region between the Eurasian and African Plates, within which several smaller fragments of plates (microplates) have been recognized.
