Yes, You Did Feel An Earthquake In Cape Town Last Night

You weren't imagining it - there was an earthquake, and people across the city felt the tremors in the early hours.

Earthquakes are rolling in on a monthly basis now.

There were tremors in September and October, measuring between 2,5 and 3,0 on the Richter Scale respectively.

On October 1, folks in Gauteng felt a shake that was confirmed to be a 2,8-magnitude tremor. The epicentre was around 5km south-east of Randfontein, in the West Rand of Johannesburg.

The one in September, which started as a 6,2 earthquake strike around 1 600 kilometres south-east of South Africa, was followed by a second, weaker earthquake (tremor) at 2,5 on the Richter scale, in far closer proximity to Cape Town.

That stirred up some anxiety because it was a little too close for comfort to the Koeberg nuclear power station.

The latest one happened at around 12:25AM on Tuesday, November 17 (this morning).

Per Cape Town Etc, shortly after the rumbling, the US Geological Survey (USGS) confirmed that it registered as a 3,5-magnitude earthquake.

According to the Earthquake Event Page, the quake hit 41km south of Saldanha, at a depth of 5km.

Residents from Paarl, all the way to Tokai and Hout Bay said they felt the shake for at least 10 seconds.

This is probably the most exciting thing to happen in Saldanha since someone set a pile of tyres alight at the harbour over 20 years ago. I was there – we all were.

No damage has been reported, and per The South African, we’re waiting for more information about whether or not it will affect tidal patterns and ocean waves.

The  community intensity map from the USGS shows where the earthquake was most acutely felt by residents in the Cape:
