4.9 quake 12 km west of Hualien City, Taiwan, 26 May 12:48 am (GMT +8)
The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 4.9 quake in Taiwan near Hualien City, Hualien, Taiwan, only 15 minutes ago. The earthquake hit after midnight on Wednesday 26 May 2021 at 12:48 am local time at a shallow depth of 19 km. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from Indonesia's Meteorology, Climatology, and Geophysical Agency which listed the quake at magnitude 4.7.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Hualien City (pop. 350,500) located 12 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Puli (pop. 86,400) located 53 km from the epicenter, Zhongxing New Village (pop. 25,500) 82 km away, Nantou City (pop. 105,700) 84 km away, Taichung (pop. 1,040,700) 85 km away, Yuanlin (pop. 124,700) 93 km away, Yilan (pop. 94,200) 94 km away, and Douliu (pop. 104,700) 100 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Taipei (pop. 7,871,900) located 122 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
