I've checked in
sys.triggers and I can't see anything related to what operation the trigger fires on.
sys.triggers table does not expose this data, instead we have two options:
Using the OBJECTPROPERTY metadata function we can return the action as a property as below:
OBJECTPROPERTY(object_id, 'ExecIsUpdateTrigger') OBJECTPROPERTY(object_id, 'ExecIsInsertTrigger') OBJECTPROPERTY(object_id, 'ExecIsDeleteTrigger')
This will return a simple bit value indicating whether the trigger fires on that particular action.

type is a foreign key to the
sys.trigger_event_types table -
type_desc seems to contain the
type_name column from the
This data can be returned using the following script:
SELECT [o].[name] ,[t].[type_desc] FROM [sys].[trigger_events] AS [t] INNER JOIN [sys].[objects] AS [o] ON [o].[object_id] = [t].[object_id] WHERE [o].[name] = 'TriggerNameHere';
