I found this article that explains why all the smaller quakes are showimg now.

"The absence of tremor in the signal in turn allows to detect tiny quakes of magnitudes below 2, which leads to an increase in the number of total detected quakes - IGN reported 129 events, but only 5 of them were at least of magnitude 3 and none above 3.2, which is among the lowest-by-energy combined values counts since the beginning of the eruption."
