35.4 km NNE of epicenter [Map] / Moderate shaking (MMI V) : There was a noise that preceded the shaking. The shaking was the biggest I've felt here. I'm a geologist, and I can feel most earthquakes in my home. This time, windows rattled, my back door shook, my mask fell off the table. Could feel both P and S waves distinctly. | 8 users found this interesting.
Aurora Reykjavik, Grandi, Reykjavik 101 (35.8 km NNE of epicenter) [Map] / Light shaking (MMI IV) : Was inside, but felt like the building may have been hit by a vehicle, and got up to check, before I realized what it was- upon hearing the building groan.
35.6 km NE of epicenter [Map] / Very weak shaking (MMI II) : I saw a bottle of water on the table moving / shaking, while no one and nothing was touching the table. Vesturbær, Reykjavík.
Reykjavik (34.9 km NE of epicenter) [Map] / Light shaking (MMI IV) : Noticeable rumbling for a few seconds. Somewhat more than the usual "moving furniture upstairs" sensation of a typical minor quake around these parts.
