The rains that were registered on Monday activated some of the most critical ravines that exist in the city of Arequipa.
This is the Chullo torrentera, which last Monday exceeded the level of flow at more than 4 meters high.
The activation of this gully, which crosses the Yanahuara district (between Calle Grande and Av. Metropolitana) caused the rupture of a drainage pipe in the Las Orquídeas urbanization. Likewise, it caused the concern of the neighbors for repeating once once more the misfortune that occurred in February 2020, following the entry of the mudslide that left several houses flooded and others to collapse.
The architect Ana Polanco Aguilar, responsible for the Operations module of COER Arequipa, told El Búho that the Chullo stream is considered one of the most critical ravines. This is due to the reduction in the width of the channel in the Primavera and Independencia sectors, she explained.

But it is not the only ravine that causes concern. Three other gullies that cross the city of Arequipa are also in this condition. These are: San Lázaro, Venezuela and Los Incas.
Although this time no incidents have been recorded so far in these three ravines. However, the specialist recalled that in 2013 the intense rains caused the dry riverbed of Venezuela to be activated, flooding dozens of homes and the El Palomar market. The emergency left four people dead.
While the entrance of the Los Incas torrentera flooded in 2020 the terrestrial terminal and terreport of Arequipa. And in 2020, the La Chavela bridge
Houses settled on bad soils
Regarding the emergencies registered in the upper part of the districts of Cayma and Alto Selva Alegre, Polanco Aguilar argued that the population built their homes in risk areas due to ignorance.
“People think that it is flat ground or without slope and that there is no danger. But the soils are volcanic deposits, they are not very compact but rather loose, stirred up”he expressed.
During the rainy season, natural drainage is formed and the houses that are in these areas end up affected, especially if the construction is not adequate either, he added.
The specialist called on the municipalities of Arequipa to apply contingency and prevention plans to prevent major disasters from occurring.
