Two aftershocks were felt in the Cape on Sunday morning.

When the earth begins to relax after an earthquake, there are almost always aftershocks.

It is dead normal and the aftershocks are usually in orders lower than the original tremor.

If one looks at the tectonic plates of the earth where the plates touch each other and move against each other, then it is not at all surprising that there are now, even in stable areas like the Cape, earthquakes.

One simply thinks back to Tulbagh.

The earth’s tectonic plates.

The original earthquake was far out to sea and we must also remember – and this is very important – that the Richter scale is a logarithmic scale. The further the scale climbs to strength 6.0, these tremors become severe.

So far, these aftershocks have been felt:

• Saturday night, an aftershock was felt at 8:41 p.m. The strength was 2.5.
• Sunday morning another aftershock was felt at 09:12. The strength was 2.3. There was another quake shortly afterwards, but it has not been recorded yet.
