Alicudi, Italy Marriage records after 1910

Hi, I've looked everywhere I can think of to find marriage records for my great grandparents on my paternal side and have hit a roadblock as I cannot find marriage records for Alicudi after 1910 and all my data shows them marrying around 1920.

Can you advise if there are any such records available online and how to find them or how I can go about obtaining this information to continue my tree.

Thanks in advance.
