1. An avalanche triggering system including:
a portable unit configured to be carried by an operator, the portable unit comprising a gas storage device configured to store an oxidizing gas and a combustible gas,
an explosion unit which is configured to be launched by the operator and which is fluidly connected to the portable unit, the explosion unit including a flexible envelope which is configured to be at least partially filled with an explosive gas mixture formed by combustible gas and oxidizing gas coming from the gas storage device, the flexible envelope being deformable between a rest configuration in which the flexible envelope has a first inner volume and an inflated configuration in which the flexible envelope has a second inner volume which is greater than the first inner volume and is at least partially filled with the explosive gas mixture, the explosion unit further comprising an ignition device which is configured to trigger the explosion of the explosive gas mixture contained in the flexible envelope, and
a control unit which is configured to remotely control the ignition device.
