A magnitude 5.6 earthquake shook buildings in Taiwan on Thursday morning, as a series of temblors hit the island, causing little damage but possibly portending more seismic activity in the near future.

Last April, a magnitude 7.4 quake hit the island’s mountainous eastern coastal county of Hualien, killing at least 13 people, injuring more than 1,000 others, collapsing a hotel and forcing the closure of Toroko national park. That was the strongest earthquake in 25 years and was followed by hundreds of aftershocks.

Taiwan experienced a 6.4 magnitude earthquake on Tuesday. The quake struck near the city of Chiayi in Taiwan’s south, according to Reuters, and it shook buildings in Taipei. TSMC said it evacuated personnel from some buildings and the science park in Tainan,
