European and Chinese people with the majority being between Portuguese and Chinese people. These unions between Chinese men and Portuguese women resulted in children of mixed parentage, called Chinese-Portuguese. For two years to June 30, 1933, 38 of these children were born; they were classified as pure Chinese because their fathers were Chinese. Curiously, these marriages are in marked contrast to the situation in Macau, where very few Han Chinese married Portuguese settlers; instead, the Portuguese mixed with indigenous Tanka people, leading to the Macanese people. Capelinhos Volcanic Eruption and the Azorean Refugee Act of 1958 In 1957–58, the Capelinhos volcano erupted on the Azorean island of Faial, causing massive destruction from lava and smoke. In response, then Senators John F. Kennedy and John Pastore co-sponsored an Azorean Refugee Act. President Dwight Eisenhower signed the legislation in 1958, making 1,500 visas available to the victims of the eruption. An extension was enabled in 1962, providing opportunities for even more immigrants. According to the United States Census from 2000, there were 1,176,615 Portuguese-Americans, the majority being of Azorean descent. This led to the passing of the 1965 Immigration Act, which stated if someone has legal or American relatives in the United States, they could serve as a sponsor and, therefore could be a legal alien. This act dramatically increased Portuguese immigration into the 1970s and 1980s.
