Most mountains in Sendai are dormant volcanoes , much older than the more famous Mount Zaō and Naruko volcanoes in nearby municipalities . However , many hot springs can be found in the city , indicating hydrothermal activity . The Miyagi Oki earthquake occurs offshore Sendai once every 25 to 40 years . The 7.2 magnitude 2005 Miyagi earthquake , which occurred on August 16 , 2005 had an epicenter close to the '' Miyagi Oki '' earthquake area . However , the Headquarters for Earthquake Research Promotion concluded that it was not the '' Miyagi Oki '' earthquake , saying " ... the recent event is not thought to be this earthquake . This is because the magnitude of the earthquake was small , and the source area , which was estimated from the aftershock distribution and seismic waves , did not cover the whole expected source region . Although , the recent event ruptured a part of the focal region of the expected earthquake . " In 2011 , the 9.0 magnitude 2011 Tōhoku earthquake occurred offshore Sendai , resulting in a devastating tsunami
