The equivalent is Hangup. Channel lifetimes are marked by "Newchannel"
and "Hangup".

Really, it's just an artifact of historical AMI. The interface has
always indicated a new channel using "Newchannel", and its termination
with "Hangup". Bridges - as a first class citizen - are new in 12+,
and hence have a slightly different convention that follow a more
familiar nomenclature.

While we renamed a decent chunk of AMI events in 12+, "Newchannel" and
"Hangup" are so ubiquitous that renaming those two - in particular -
would have hurt a lot of implementations. Hence we opted to keep the
names the same.
