"I felt it" reports:
Academia Sinica, Nangang, Taipei / MMI VI (Strong shaking): Loud rumbling noise. Saw the room "move". The earthquake equivalent of "wash, rinse, repeat". Felt the first quake from the fourth floor. By the time I type this, at least three quakes felt. Same feeling, same impact. In one 24 hour period in Taiwan I have felt more quakes than in 30 straight years in California, from 1970 to 2000.
