This handout picture taken by Pleiades satellite and released on September 27, 2013 shows a small island of mud and rock created by the huge earthquake that hit southwest Pakistan has fascinated locals but experts – who found methane gas rising from it – say it is unlikely to last long.

The island is about 60 to 70 feet (18 to 21 metres) high, up to 300 feet wide and up to 120 feet long and sits about 650 feet from the coast. (Photo by AFP Photo/CNES/Distribution Astrium Services)

“Igor Fyodorovich Stravinsky (17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian-born, naturalized French, later naturalized American composer, pianist, and conductor. He is widely acknowledged as one of the most important and influential composers of 20th century music. He was a quintessentially cosmopolitan Russian who was named by Time magazine as one of the 100 most influential people of the century. He became a naturalized French citizen in 1934 and a naturalized US citizen in 1945. In addition to the recognition he received for his compositions, he also achieved fame as a pianist and a conductor, often at the premieres of his works”. – Wikipedia
