A Spanish judge is intensifying the investigation into the handling of the October 29 storm that caused 227 deaths in Valencia.

Judge Nuria Ruiz Tobarra has tasked the Guardia Civil with examining the emergency coordination center's video surveillance and communication systems.

The inquiry focuses on why a critical mobile alert was delayed until hours after the disaster began.

The judge is also seeking records of staff present at the center and details of the emergency flood plan.

Accusations of negligence have been raised against key officials, with claims that earlier action could have saved lives.

The investigation continues to uncover potential lapses in crisis management.
