How to determine why the remove event of backbone collection is triggered?

Remove event on backbone collection is triggered when the model has been removed from the collection.

But I need to differentiate whether destroying the model triggers the remove event on collection or just removing the model from collection triggers the remove event on collection.

There's no easy way to differentiate those two cases. My recommendation would be to override the remove method yourself and have it trigger your own event(s):

var YourCollection = Backbone.Collection.extend({
    remove: {
        this.trigger('aboutToRemovedViaRemoveMethod');
        // Call the original remove
        var removeResult = Backbone.Collection.prototype.remove.apply(this, arguments);
        this.trigger('removedViaRemoveMethod');
        return removeResult;
    }
});

And then of course destroy you can already listen for separately, as it has its own event.
