AB: Slope instability is presented each year in Colima State during rain season ( May to November). Here we show description and analysis of the principal factors that originate risk to the population that live especially in the North part of the Colima state due to these geological phenomena. The hydrology of the region will be presented to calculate the hydrological balance. Analysis of the topography and erosion of the state will be described here to present a zonification of the areas where the instability risk will be dangerous to the population of the state. Colima state is located in the central western part of Mexico limited by the Pacific Ocean on South and it is surrounded by the Jalisco and Michoacan States. It is located between the Trans Mexican Volcanic Belt and the Sierra Madre del Sur Provinces. The Colima Volcano is located in the northern part of the state. Physiographical the state is characterized to have 50.5 % Mountain range, 23.4 % Plain, 14.6 % Valley, 9.3 % Hill and 2.4 % Plateau. More than 600,000 inhabitants are living in an area of about 5,542.74 km2. The weather is influenced principally by the mountain range relief which is covered at North and West of the state where the high precipitation occurred, high elevation and cold temperature is found there. These factors contribute to accelerate the instability of materials deposits in the North part of Colima as here presented.
