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 severity of an earthquake is called its magnitude. Various scales were proposed to measure the magnitude of earthquakes until 1935, when the Richter Scale was developed by a seismologist named Conrad Richter to measure the intensity of the seismic waves.
