Officials are monitoring increased seismic activity at Kīlauea volcano within Hawaiʻi Volcanoes National Park, which has prompted temporary closures of parts of the Halemaʻumaʻu Trail and Byron Ledge Trail due to safety concerns. Over 200 shallow earthquakes were recorded beneath the summit last week, with a magnitude-3.4 quake causing rockfalls along the caldera's north wall. The USGS has issued an orange aviation color code warning about potential hazards from volcanic activity, including gas emissions and skin and eye irritation from small glassy fragments.

Story summary
Kīlauea volcano at Hawaiʻi Volcanoes National Park experienced renewed spattering at two vents following recent seismic activity beneath its summit, leading the U.S. Geological Survey (USGS) to issue a volcanic activity notice earlier this week. On Wednesday, the National Park Service (NPS) announced temporary closures of 1.3 miles of trails, including parts of Halemaʻumaʻu Trail and Byron Ledge Trail due to increased seismic activity and concerns over rockfalls. Over 200 shallow earthquakes were recorded beneath Kīlauea's summit during the past week, with a magnitude-3.4 earthquake on September 30 causing small rockfalls along the caldera's north wall. As of Thursday, Kīlauea remained at an ORANGE aviation color code, indicating heightened volcanic activity and potential eruption risks, though limited hazards to aviation currently exist.

Kīlauea remained at an ORANGE aviation color code, the second-highest level on the USGS' four-tier scale, as of Thursday.
asserted
Kīlauea → remain → Thursday
The designation indicates heightened volcanic activity and the potential for an eruption, or an eruption underway with limited hazards to aviation.

The intrusion, which occurred from Sept. 30 to Oct. 1, is believed to have caused new cracks along the caldera floor, according to scientists.

Scientists said they cannot forecast when — or if — the volcano's 55th episode of lava fountaining will occur.
asserted
episode → say → fountaining
"Forecast windows for episode 55 fountaining can no longer be modeled due to changes in conditions," the USGS advisory said.

Officials also outlined several hazards for residents and visitors, including potentially dangerous gas emissions and small, glassy volcanic fragments that can cause skin and eye irritation.
asserted
that → outline → irritation
"Small glassy volcanic fragments may be remobilized during windy conditions following recent eruptive episodes," the statement added.
uncertain
statement → remobilize → episodes
"Residents and visitors should minimize exposure to these fragments, which can cause skin and eye irritation.
asserted
which → minimize → irritation

Visitors must also stay out of closed areas and away from unstable cliff edges, which can collapse without warning, according to the NPS.

Eruptive activity was nearly continuous along the volcano's East Rift Zone from 1983 to 2018, a 35-year stretch that ended amid significant eruptive activity and a collapse at the summit, the agency said.
asserted
