The Environmental Prosecutor's Office in Las Palmas has opened investigative proceedings to clarify the extent of the damage to the Arguineguín ravine in Gran Canaria, caused by the heavy rains from Storm Therese between March 18 and 24, 2026. Sources close to the ongoing investigation have confirmed the commencement of these actions.

This initiative follows a complaint filed by the Citizen Platform Save Chira Soria and Arguineguín Ravine. The group requested the Prosecutor's Office to investigate the alleged commission of four offenses related to the breach of emergency regulations during the management of the meteorological crisis. According to the platform, these anomalies reportedly led to the isolation of approximately 3,000 people and endangered lives, necessitating rescues due to strong currents in the ravine that borders the municipalities of Mogán and San Bartolomé de Tirajana.

The provincial Environmental Prosecutor has requested documentation from all involved administrations, particularly the Insular Water Council. The aim is to ascertain whether potential alterations to the ravine, resulting from the construction of the Salto de Chira hydroelectric power plant, may have intensified the risk to the settlements along the ravine.

The plaintiff platform believes that the negligent management of hydraulic infrastructures could constitute a crime of catastrophic risk due to gross negligence. They also point to potential offenses against natural resources and the environment for discharges and actions damaging ecosystems, administrative prevarication by omission in fulfilling legal duties for prevention and alerts, and omission of the duty of assistance or professional negligence due to the failure to activate alerts and disregard for population risks.
