According to Focus Taiwan, the intensity of the quake measured 4 on Taiwan’s 7-tier intensity scale in Tainan, Kaohsiung, and Chiayi County. The quake also registered an intensity of 3 in Chiayi City, Yulin County, Changhua County, and Taichung. There were no immediate reports of damage following the quake.

Wu Chien-fu, director of the CWA’s Seismological Center, told CNA that the earthquake was an aftershock of the January 21 earthquake in Chiayi County’s Dapu Township, which had a magnitude of 6.4. Wu noted that aftershocks with magnitudes above 5 may still occur in the Chiayi Dapu and Tainan Nanxi areas in the future. However, the frequency of larger earthquakes is decreasing as seismic energy is gradually being released.

Mos
t future aftershocks are expected to fall within the magnitude 4 to 5 or 3 to 4 range, following a standard pattern of attenuation based on statistical observations, Wu said.
