DBE/2022 EXTRACT 1 EXTRACT 2 In a single day on Earth, thousands of eafthquakes may occur, but it is the big/éarthquakes that are usually of interest to people. (An earthquake is considered to be big if it has a magnitude of 7.0 or greater on the Richter scale.) These quakes can cause major damage and loss of life. On average worldwide, about 18 earthquakes per year qualify as big. [Source: https://www.usgs.gov/natural- hazards/earthquake-hazards/earthquakes] ‘Wobble’ may precede some great earthquakes New research shows that in the months before the strongest earthquake in the country's recorded history, a 2011 earthquake with a magnitude of 9 on the Richter scale that killed more than 15 500 people, the land masses of Japan shifted from east to west to east again. Those movements that researchers call a ‘wobble’, may have the potential to alert seismologists to a greater risk of future large subduction-zone earthquakes. These destructive events occur where one of Earth's tectonic plates slides under another one. This underthrusting jams up or binds the earth, until the jam is finally torn or broken and an earthquake results.

Graaff-Reinet is the main centre of the Camdeboo Municipality (population in 2002, 44 354) and is built in an area known as ‘the horseshoe’ where the Sundays River makes a loop almost encircling the old town. The town is 750 metres above sea level. Few towns have conserved their historic townscape as well as Graaff-Reinet, with the result that the town has more protected buildings than any other in South Africa. In Graaff-Reinet, the summers are hot; the winters are short, cold, dry and windy; and it is mostly clear year round. Over the course of the year, the temperature typically varies from 5 °C to 33 °C and is rarely below 2 °C or above 39 °C.
