Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Iya volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 January-14 January 2025 (Continuing Activity)

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported a decrease in seismicity at Iya during 5 November 2024-7 January 2025. Deep earthquakes indicating a magma presence continued to be recorded, and continuous tremor persisted but with a decreasing amplitude. In general, white emissions rose as high as 500 m above the summit and drifted in multiple directions, though emissions that rose 10-200 m above the crater rim during 1-7 January were characterized as white-and-gray. ...
