A magnitude 5.9 earthquake struck in the sea off of Hualien at around 3 a.m. on Oct. 11. This was the 55th earthquake with a magnitude of over 5 so far this year.
A security camera inside a person's home shows the moment the earthquake struck. The sudden shaking startled a puppy. The magnitude 5.9 tremor struck at 3:24 a.m. on Oct. 11 off the coast of Hualien. It was felt across Taiwan, with an intensity level of 4 in Hualien County's Heping Village. Many people were shaken awake.
Hualien County Resident: “I got up to take a look. (Did it feel really intense?) The shaking lasted for quite some time.”
The Central Weather Bureau's Seismological Center said this earthquake and the 918 earthquake are unrelated, and has an independent earthquake sequence. It was caused by the subsidence of the Philippine plate into the Eurasian plate. A magnitude 6.0 earthquake occurred in January, and this region is an earthquake-prone region. Taiwan has already entered into a seismically active period, with 55 earthquakes with a magnitude of 5 or above so far this year.
Chen Kuo-chang, Director, Seismological Center, CWB: “I said on Jan. 3 that the earthquake activity this year will continue to be quite active.”
Chen Wen-shan, Retired Professor, Dept. of Geosciences, NTU: “There's no need to worry if there are successive earthquakes but they are limited to that small region. What we should worry about is that region to the south. This seismic zone in Japan extends to Miyako Island. A study that Japan completed 10 years ago said that this area could potentially experience tsunamis.”
Experts say what's of concern is the area to the south of where this earthquake occurred. It hasn't experienced any earthquakes in the past decade. It extends to Miyako Island and tsunamis could occur here. Relevant units are urged to actively understand the risks by investigating active faults on land or deploying seismometers onto the seabed.
