The Prefect of La Réunion calls on hikers to be extremely vigilant on the Piton de la Fournaise massif due to the presence of uncooled and unstabilised flows in the prohibited zones, presenting a high risk of degassing harmful to the health. Security markup is non-existent or interrupted beyond authorized limits, greatly increasing the risk of getting lost. He also recalled that the volcano is a natural environment, subject to very rapid and sometimes violent weather changes. Recommendations for mountain safety apply in particular.
