What is the difference between State of Alarm and State of Emergency?

The Spanish constitution includes some limitations of constitutional rights and freedoms when exceptional circumstances make it advisable, as is the current case we are living. The constitution includes three states of emergency, the current "State of Alarm" being the least restrictive in terms of the limitation of rights and freedoms, followed by the state of exception and siege, the latter being the most restrictive and detrimental to the exercise of fundamental rights and freedoms (Art. 116 C. E.).
