Signal 15 is pretty much equal to a regular shutdown, except that if your shutdown script doesn't run, you may be left with lockfiles, pidfiles and the like.
A crash would most likely be visible in the logfile, and even if it isn't (machine loses power), your log should show innodb running a recovery procedure at startup.
