Argentina regularly receives cold air from the south that can reach low latitudes owing to the influence of the Andes. Cold waves are often accompanied with severe snow storms or extremely cold conditions that can have a devastating impact on its economy.
The Richter Scale measures the magnitude of an earthquake which is  another way of describing the energy released in the earthquake.
The Richter Scale measures magnitude, the amount of energy released by an earthquake by measuring how big a shock wave is. Each number on the scale is 10 times more powerful than the number below it. A magnitude 3 earthquake is ten times greater that a magnitude 2 and is easily felt. An earthquake that registers 6 or more is considered a major quake.
