( CNN ) -- A 6.4-magnitude earthquake jolted southern Taiwan on Thursday morning , according to the U.S. Geological Survey . There were no immediate reports of injuries or deaths but some damage has occurred to buildings and major bridges , and power was cut off near the epicenter . The quake struck at about 8:20 a.m. ( 7:20 p.m. Wednesday ET ) in a mountainous region about 25 miles northwest of Taitung , on the southeast coast , and 40 miles east of Tainan and Kaohsiung on the southwest coast . The region , which includes Maolin National Scenic Area , is recovering from a direct hit by Typhoon Morakot that killed hundreds in August . The typhoon dumped more than two feet of rain , causing serious mudslides in the south , including one that buried the village of Shiao Lin under 50 feet of mud . Thursday 's quake was followed by several aftershocks , the largest reaching 4.8 . The initial 6.4 quake rumbled to the surface from 14 miles deep . Were you there ? Did you feel it ? The Taiwan Ministry of Interior and the National Fire Agency said electricity was cut off near the epicenter but had no further information . Residents in southern Taiwan reported cracks in some buildings and major bridges . Train service was also disrupted in some areas , Taiwanese media reported . Albert Yu , communications manager of the humanitarian organization World Vision , told CNN he was about halfway through a 90-minute trip via high-speed train from Taipei to Tainan when the quake struck . Passengers did not feel the quake , he said , but operators stopped the train and announced what had happened . More than an hour later , the train had not resumed its journey . `` The operator is examining the train and the tracks , '' he said , adding that there was a concern about the stability of the area , particularly after the typhoon . `` Inside the train , people are calm and are waiting it out -- opening laptops , starting to work and chatting with people around them . '' Yu said World Vision `` has already been on high alert responding to the quakes in Haiti and Chile , so we 're closely monitoring reports in the earthquake in southern Taiwan . '' Residents in the capital Taipei , 155 miles to the north , also felt the shaking . Earthquakes are not uncommon in the 13,892-square-mile island -- about the size of the U.S. states of Maryland and Delaware combined -- which sits across the juncture of the Eurasian and Philippine tectonic plates . A 6.4-magnitude earthquake struck the same general region in December . The island took a double hit on December 26 , 2006 , when earthquakes of 7.1 and 6.9 magnitude hit eight minutes apart . The largest recorded quake to strike Taiwan was an 8.0-magnitude quake in 1920 , but the worst earthquake disaster stemmed from a 7.1-magnitude quake in 1935 that killed more than 3,200 people -- followed by a 6.5-magnitude quake that killed more than 2,700 people three months later . More recently , a 7.6-magnitude earthquake killed more than 2,400 people in 1999 . CNN 's Christine Theodorou and Journalist Andrew Lee contributed to this report .
