On 30 and 31 August 1923, when violent earthquakes destroyed a large part of the cities of Tokyo and Yokohama, Japan, the Commander in Chief of the Asiatic Fleet, Admiral Edwin Anderson, Jr., dispatched all available vessels to that area with emergency supplies to render assistance. "Sicard" arrived in Yokohama harbor on 11 September and acted as dispatch boat to Tokyo and transported refugees from the city. From 25 September to 3 October, she was stationed in Nagasaki harbor as relay ship, since all radio communications to Yokohama and Tokyo were out of commission. The prompt action of "Sicard" and other units of the Asiatic Fleet helped save thousands of lives and earned the thanks of the Japanese government. Between 26 April and 30 June 1924, "Sicard" again saw special duty, in connection with the flight of four United States Army airplanes around the world. The destroyer cruised from Hong Kong to Rangoon, Burma, and Calcutta, India, guarding the flight and maintaining radio communications. During the next few years, "Sicard's" patrols in Chinese waters became more frequent due to the fighting which accompanied Chiang Kai-shek and the Kuomintang prevailing over warlords. On 22 July 1929, having been relieved by another squadron, "Sicard" and her squadron sailed from Yokohama, Japan, for the United States and arrived at San Diego on 17 August.
