TIJUANA, Mexico At least 23 dwellings were destroyed over the weekend by landslides in the northwestern Mexican border city of Tijuana, but no injuries were reported, emergency management officials said.
We have a 20-meter (65-foot) slope and there are many factors that may have initiated this, but from what we can see this is a natural phenomenon, Tijuana emergency management office director Jose Rito Portugal said Sunday.
Residents of the Reforma district have been detecting cracks in the walls of their homes for two weeks, but they did not notify authorities until last Friday, when the cracks widened, the emergency management official said.
Emergency management office inspectors took preventive measures, posting warning signs on 11 houses at risk of collapse and warned residents of the danger if they remained in the structures.
On Saturday, officials placed warning signs on nine additional houses and evacuated the residents, while the city government set up a mobile emergency operations center.
A few hours later, four houses collapsed and 18 other dwellings were destroyed on Saturday afternoon and night. On Sunday, another house was destroyed.
