In SharePoint you can only view alerts per site. That means you cannot see all your alerts at once.

View my alerts on a site

At the top of the site, click User name , and then click My Settings, click My Alerts.

View alerts for other people on a site

As a Site Administrator you can view alerts of other users on your site through Site Actions -> Site Settings -> Under Site Administration -> User Alerts select the person whose alerts you want to view and select Update.

View all my alerts

There are several solutions for this, CodePlex and other SharePoint companies have some.
Outlook to the rescue! If you are using Exchange your Exchange mailbox will keep track of all your alerts and where these are subscribed from.
Choose Rules and Alerts.. select the Manage Alerts tab.
