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 Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake, and is distinct from the moment magnitude M w {\displaystyle M_{w}} usually reported for an earthquake (sometimes misreported as the Richter magnitude), which is a measure of the energy released. The intensity of an earthquake is not entirely determined by its magnitude.
