Moodus is a village in the town of East Haddam, Connecticut, United States. The village is the basis of a census-designated place (CDP) of the same name. The population of the CDP was 1,413 according to the census of 2010.
Prior to its purchase by English settlers in 1662, the area around Moodus was inhabited by Native American Algonquians, three of which tribes are known: the Wangunks, the Mohegans and the Nehantics. The name was derived from the Native American name for the area-- "Matchetmadosett" or "Matchitmoodus", the place of noises, possibly because of earthquakes. Numerous earthquakes were recorded in the area between 1638 and 1899. Loud rumblings, the “Moodus Noises,” could be heard for miles surrounding the epicenter of the quakes near Mt. Tom. The land, which is now the towns of Haddam and East Haddam, was purchased by settlers from the Indians during 1662 for thirty coats – worth about $100. The Native Americans worshipped the god of the dead in the land known as Matchetmadosett.
