Is it possible to restart restarted erlang applications automatically?

Question

I have my_app application. He has other applications on which it depends.

my_app.app:

{application, my_app,
 [ {description, "My App"},
   {vsn, "0.0.1"},
   {registered, []},
   {applications, [some_dep1,
                   some_dep2]},
   {mod, {my_app_app, []}},
   {env, []}
 ]}.

If it is impossible to start some_dep1or some_dep2, it my_appalso will not start. So far so good.

However, if something goes wrong while the system is running and some_dep1explodes (takes supervisors to the whole tree), erlang will eventually destroy the application some_dep1; however my_app is not killed and it will not be notified (what can I find)

Is there any way to handle this? Ideally, I would like it to restart (just like supervisors handle reboots, with thresholds, etc.) Or, alternatively, they kill any applications that depend on it.
