Rivadavia c. 1914–15, possibly on a speed trial

The two Rivadavia-class battleships were constructed for Argentina as a part of a wider South American naval arms race. To counter Brazil's two Minas Geraes-class dreadnought battleships, Argentina began seeking bids for at least two of their own in 1908. Over the next two years, multiple shipbuilders from five countries vied for the contracts, complemented by efforts from their respective governments. Argentina's choice in early 1910 of the Fore River Shipbuilding Company, based in the United States, shocked the European bidders, but could partly be explained by the American steel trust's ability to produce steel at a lower cost than any other country. Amid increasing tension in Europe that would lead to the First World War, newspapers speculated that the Argentine dreadnoughts would be sold to a European nation. Under diplomatic pressure, the Argentines decided to keep the ships; after numerous delays, they arrived in the country in February and May 1915. The dreadnoughts were modernized in the 1920s, and in the latter half of their life were frequently employed as training ships and diplomatic envoys. Both were sold for scrap in the late 1950s.

Alpine Fault

Snow delineates the escarpment formed by the Alpine Fault along the Southern Alps' northwest edge, near the South Island of New Zealand's west coast, in a satellite image showing the aftermath of a blizzard that hit the island in July 2003. This geological fault, which forms a transform boundary between the Pacific Plate and the Indo-Australian Plate, has experienced numerous earthquakes over the past millennium, including four which reached magnitude eight on the Richter scale.
