Is there a way to add a function that will get run after a blog is created?

Is there a way to have a function run after a blog is created in WP MU? I think I would need to add a filter or something but I’m not as familiar with the procedure.

Do I set something up like this:

EXAMPLE!!!
add_filter('new_blog_created', 'my_function');


function my_function() {
    // do something
}

So far I’m calling wpmu_create_blog() to create a new blog successfully if that helps.

Here is my code which is inside a function:

function create_site() {
    // some code
    $meta = apply_filters( 'add_signup_meta', $meta );

    $result = wpmu_create_blog( $domain, $path, $blog_title, $current_user->ID, $meta, $wpdb->siteid );

}
