It creates an empty repository in the path specifies by repo_path. Subversion has two types of backend for the repository: BerkleyDB and FSFS. In the first one an embedded Berkley DB database stores the versioned data; in the second the data is stored in flat files using a custom format. As of Subversion 1.2 the default type is FSFS and the type can be changed using -fs-type:
# svnadmin create --fs-type bdb <repo_path>
