Moderate yet deep 5.4 quake hits near Tomakomai, Tomakomai Shi, Hokkaido, Japan
5.4 quake 27 Jan 2:06 pm (GMT +9)
5.4 quake 27 Jan 2:06 pm (GMT +9)
A intermediate magnitude 5.4 earthquake was reported early afternoon near Tomakomai, Tomakomai Shi, Hokkaido, Japan.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Wednesday 27 January 2021 at 2:06 pm local time at an intermediate depth of 115 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.7.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Chitose (pop. 92,900) located 34 km from the epicenter, Tomakomai (pop. 174,800) 35 km away, Kitahiroshima (pop. 62,400) 49 km away, Ebetsu (pop. 134,000) 61 km away, Iwamizawa (pop. 85,100) 61 km away, Sapporo (pop. 1,883,000) 69 km away, Bibai (pop. 29,000) 72 km away, Muroran (pop. 96,200) 95 km away, and Obihiro (pop. 173,900) 99 km away.
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.
