On 14 December 2020, significant rains occurred in the municipality of Presidente Get\u00falio, in the State of Santa Catarina in southern Brazil<\/a>. According to residents’ reports on the night of 17-18 December 2020, the rains intensified from about 10:30 pm to 11:30 pm, and widespread dangerous geological processes were triggered.<\/p>\n

There were 21 deaths in the region across three municipalities: 18 in Presidente Getulio, two in Rio do Sul, and one in Ibirama.<\/p>\n

The cumulative rainfall in the last 30 days before the disaster, indicates a total greater than 370 mm in the period, according to data recorded at the Jardim Otilene weather station of the National Center for Monitoring Natural Disasters (CEMADEN)<\/a>, which is located in the centre of the municipality:<\/p>\n

Most of the larger mass movements in the Presidente Get\u00falio region initiated as translational type landslides in the Palaeozoic sandstone escarpments. The dangerous geological processes identified in this event included landslides, rock falls, debris flow, floods and flash floods, mainly affecting the Rev\u00f3lver Creek valley in Presidente Getulio, and the Cobras Creek valley in the municipality of Rio do Sul. High-energy surface water flows, transporting logs, pebbles, sand, clay and debris, reached the lower portions of the valleys, causing destruction in rural areas and in the urban area of the city of Presidente Get\u00falio.<\/p>\n

Consequently, several roads and bridges were destroyed, houses were damaged or destroyed and agricultural and industrial activities were impacted, achieved by these geological processes of high destructive capacity.\u00a0 The images below show some these events:<\/p>\n
