Question: Typhoon Nanmadol was derived from the name of a ruined city that was the capital of the Saudeleur Dynasty until when?

 It is in the present day Madolenihmw district of Pohnpei state, in the Federated States of Micronesia in the western Pacific Ocean.  The city, constructed in a lagoon, consists of a series of small artificial islands linked by a network of canals. Nan Madol is an archaeological site adjacent to the eastern shore of the island of Pohnpei that was the capital of the Saudeleur Dynasty until about 1628.  The site core with its stone walls encloses an area approximately 1.5 km long by 0.5 km wide and it contains nearly 100 artificial islets—stone and coral fill platforms—bordered by tidal canals. <SEP>  It was the eleventh named storm, the seventh severe tropical storm and the fourth typhoon of the 2011 Pacific typhoon season.  Nanmadol made a total of three landfalls killing 26, and causing widespread damage worth US$26,464,591. Typhoon Nanmadol, known in the Philippines as Typhoon Mina, was the strongest tropical cyclone in 2011 to hit the Philippines and also the first of the year to directly impact Taiwan and the rest of the Republic of China (ROC).  The name "Nanmadol" is derived from Nan Madol, a ruined city that lies off the eastern shore of the island of Pohnpei that was the capital of the Saudeleur dynasty until about AD 1500. <SEP> Typhoon Nanmadol, known in the Philippines as Typhoon Yoyong, was the last of four consecutive tropical cyclones to strike the Philippines in 2004.  A quickly moving system, Nanmadol brought heavy rainfall and strong winds over the same regions impacted by the previous storms, exacerbating flood conditions in Luzon and surrounding regions.  Together Nanmadol and these systems accounted for around 1,000 deaths in the Philippines.  The typhoon later became the first December tropical cyclone to strike Taiwan since record keeping began, bringing along with it heavy rain, which also affected nearby regions of eastern China.  As an extratropical storm, Nanmadol brought gusty winds and rain to Japan. <SEP> Ji (蓟/薊 Jì), Jicheng or the City of Ji (蓟城/薊城 Jìchéng) was an ancient city in northern China, which has become the longest continuously inhabited section of modern Beijing.  Historical mention of Ji dates to the founding of the Zhou Dynasty in about 1045 BC.  Archaeological finds in southwestern Beijing where Ji was believed to be located date to the Spring and Autumn period (771-476 BC).  The City of Ji served as the capital of the ancient states of Ji and Yan until the unification of China by the Qin Dynasty in 221 BC.  Thereafter, the city was a prefectural capital for Youzhou through the Han Dynasty, Three Kingdoms, Western Jin Dynasty, Sixteen Kingdoms, Northern Dynasties, and Sui Dynasty.  With the creation of a Jizhou (蓟州) during the Tang Dynasty in what is now Tianjin Municipality, the City of Ji took on the name Youzhou.  Youzhou was one of the Sixteen Prefectures ceded to the Khitans during the Five Dynasties.  The city then became the southern capital of the Liao Dynasty and then main capital of the Jin Dynasty (1115-1234).  In the 13th Century, Kublai Khan built a new capital city for the Yuan Dynasty adjacent to Ji to the north.  The old city of Ji became a suburb to Dadu.  In the Ming Dynasty, the old and new cities were merged by Beijing's Ming-era city wall.
