Reply MiR Haider Ali on January 29, 2019 at 9:29 am Although Mauna Loa has historically been considered to be the largest volcano on Earth, in reality it is not the largest. By far the largest volcano in Earth is Shatsky ridge. Located in the Pacific Ocean floor east of Japan, it is an extinct volcanic complex the size of California.
