  • Torremolinos and Benalmádena are two towns affected and the study puts the subsidence down to local differences in ground sediments

An international team of experts, including researchers from the University of Malaga, has confirmed subsidence of up to 6.5 millimetres a year in two areas in Torremolinos and Benalmádena. In Torremolinos it is the La Colina area, to the east of the town, and in Benalmádena, the Puerto Marina leisure port that are both affected.

Data collected between 2015 and 2017 has been added to an original study that identified the problem between 1992 and 2009.

Experts are blaming the sinking of the land on the draining of natural water supplies from the underground channels flowing off the Sierra de Mijas mountains and increasing property development, both of which make the ground compact.

Dr Pablo Jiménez Gavilán of the university said that the earth compacting is a widespread phenomenon but is particularly pronounced in these two areas in Torremolinos and Benalmádena.

The team has asked the local councils of the two municipalities to provide information of any reported subsidence damage to buildings.

"Benalmádena showed some interest in collaborating but Torremolinos hasn't even replied," said Jiménez, adding that there was no need for any alarm.

Differences in the nature of ground sediments are believed to be behind variances in local subsidence rates.
