Kīlauea South Vent Erupts Vigorous Lava Flows as Summit Pressurization Persists
The south vent at Kīlauea volcano produced multiple lava overflows overnight on October 16, 2026, marking a shift from low-level activity to vigorous flow. The USGS Hawaiian Volcano Observatory reports that the summit remains highly pressurized, with magma likely originating from the same shallow chamber that fueled previous fountaining episodes. While no major fountaining has occurred since August, the current activity suggests the magma system is near the surface and capable of generating new flows or potential future episodes.
