For almost a year starting on 19 March 2020 when the Alert Level was lowered to 1, the bulletins of Phivolcs only reported the occurences of volcanic earthquakes. There were no other classifications of occurences.

Then on 14 February 2021, it included occurences of volcanic tremor episodes.

Then came occurences of hybrid events on 9 March 2021.

And now another kind of occurence which is low frequency earthquakes is being reported. If reported separately, then these are different from volcanic earthquakes, I supppose.

So, what other classifications are there? Better if Phivolcs lists them all and then tracks all of these. If there are no occurences for a particular classification, then they should just put 0 (zero).
