## Kīlauea Summit Erupts
Low-level lava activity returned to Kīlauea's summit overnight, continuing within Hawaiʻi Volcanoes National Park.
## South Vent Overflows
The south vent produced 15 small lava overflows starting at 10:16 p.m. HST, advancing less than 100 feet from the vent.
## High-Volume Overflow
By 5:10 a.m. HST, a high-volume overflow coated the area within 300 feet of the vent with pahoehoe lava in 10 minutes.
## Current South Vent Activity
South vent overflows began at 5:56 a.m. HST and continue, feeding multiple pahoehoe channels extending near a half mile from the vent.
## Seismic Activity
Twenty-one earthquakes were recorded overnight, mostly in the southern and eastern regions of Kīlauea's summit.
## Magma Pressure
The summit remains highly pressurized, with data showing continued inflation and possible changes in eruptive activity or location.
## Next Steps
HVO warns of possible new fountaining episodes or passive eruptions from existing weak crack systems in the summit region.
## Key takeaway

Kīlauea's south vent produced 15 small lava overflows overnight, advancing up to 300 feet from the vent by 5:10 a.m. HST.
