No, Diamond Head is not an active volcano. It is classified as a dormant volcano, meaning that it has not erupted in a very long time and is not currently active.
Diamond Head, known locally as Le’ahi, is located on the island of Oahu in Hawaii. It last erupted approximately 200,000 years ago. Since that time, it has been extensively eroded, which is characteristic of dormant volcanic craters. Although it is not likely to erupt again, it offers a stunning view and is one of the most famous landmarks in Hawaii.
