On Tisha B’av itself, if there is no event located in your location, you can watch online programs applicable to the day.
Possibly on this site, and others, there will be a livestream of lectures pertaining to the day. Use google to find Tisha B’av programs.
There are also programs presented by the Chofetz Chaim Heritage Foundation, and Project Inspire, in many locations throughout the world. If none are near you, you can probably watch them online for a fee.
Again, use google to find Tisha B’av programs video.
I hope that helps.
