HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Friday, July 21, 2017, 9:13 AM HST (Friday, July 21, 2017, 19:13 UTC)


KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō continues to enter the ocean at Kamokuna. Surface flows are active above the pali, with continued activity on the coastal plain. These flows pose no threat to nearby communities. There have been no significant changes in seismicity levels across the volcano. At the summit, there was no significant change in ground tilt and the lake level was measured at around 26 m (85 ft) below the Overlook crater rim this morning.

Summit Observations: There was no significant change in ground tilt over the past day, and the level of the lava lake was measured at about 26 m (85 ft) below the Overlook crater rim. Webcam views of the lava lake can be found at this webpage: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html. Summit tremor continues to fluctuate in response to variations in lava lake spattering and earthquakes occurred at normal, background rates. Summit sulfur dioxide emission rates remain high.

Puʻu ʻŌʻō Observations: Webcam images continue to show persistent glow from long-term sources at Puʻu ʻŌʻō. Seismic activity is at background levels, and ground tilt measurements were affected by rain over the past day. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. Several large cracks have developed in the lava delta, running parallel to the coastline and spanning the width of the delta. These cracks increase the likelihood of a large delta collapse.

Surface flows continue on the upper portion of the flow field above the pali. Minor breakouts on the coastal plain continue, roughly 2 km (1.2 mi) upslope from the gravel emergency route.

Ocean Entry Hazards: The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō continues to enter the ocean at Kamokuna. Surface flows are active above the pali, with minor activity on the coastal plain. These flows pose no threat to nearby communities. There have been no significant changes in seismicity levels across the volcano. Inflationary ground tilt continues at the summit. Yesterday afternoon, the summit lava lake level was measured at 36 m (118 ft) below the Overlook crater rim.

Summit Observations: Inflationary tilt continues at the summit this morning. The level of the lava lake has risen in concert with the tilt, and was measured at about 36 m (118 ft) below the Overlook crater rim yesterday afternoon. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php. Summit tremor continues to fluctuate in response to variations in lava lake spattering and earthquakes occurred at normal, background rates. Summit sulfur dioxide emission rates remain high.

Puʻu ʻŌʻō Observations: Webcam images continue to show persistent glow from long-term sources at Puʻu ʻŌʻō. A nearby tiltmeter recorded inflationary tilt over the past day, mirroring the summit tilt. There was a small increase in seismic activity on the East Rift Zone early yesterday, but activity has returned to background levels. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. Several large cracks have developed in the lava delta, running parallel to the coastline and spanning the width of the delta. These cracks increase the likelihood of a large delta collapse.

Surface flows continue on the upper portion of the flow field above the pali. Field observations from Thursday observed minor breakouts on the coastal plain within about 1 km (0.6 mi) of the base of the pali and 2.2 km (1.4 mi) from the gravel emergency route. Web cam views show continued activity in these areas.

Ocean Entry Hazards: The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Activity Summary: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō continues to enter the ocean at Kamokuna. Surface flows are active above the pali, with minor activity on the coastal plain. These flows pose no threat to nearby communities. The summit lava lake level has risen slightly over the past day. There have been no significant changes in seismicity levels across the volcano. Yesterday evening, Inflationary tilt began at the summit.

Summit Observations: The deflationary ground tilt recorded over the past several days switched to inflationary tilt early yesterday evening, in the most recent deflation-inflation (DI) event. The level of the lava lake has risen in concert with the tilt, but is still more than 30 m (98 ft) below the Overlook crater rim. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php. Summit tremor continues to fluctuate in response to variations in lava lake spattering and earthquakes occurred at normal, background rates. Summit sulfur dioxide emission rates remain high.

Puʻu ʻŌʻō Observations: Webcam images continue to show persistent glow from long-term sources at Puʻu ʻŌʻō. A nearby tiltmeter recorded no significant change in ground tilt over the last day, however, the long term inflationary tilt trend recorded during 2017 continues. There was no significant change in East Rift Zone seismicity. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. Several large cracks have developed in the lava delta, running parallel to the coastline and spanning the width of the delta. These cracks increase the likelihood of a large delta collapse.

Surface flows continue on the upper portion of the flow field above the pali. Field observations from Thursday observed minor breakouts on the coastal plain within about 1 km (0.6 mi) of the base of the pali and 2.2 km (1.4 mi) from the gravel emergency route. Web cam views show continued activity in these areas.

Ocean Entry Hazards: The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water. Also, the lava delta is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Activity Summary: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō continues to enter the ocean at Kamokuna. Surface flows are active above the pali, as well as on the coastal plain, within about 1 km (0.6m) of the base of the pali. These flows pose no threat to nearby communities. The summit lava lake was about 30 m (98 ft) below the Overlook crater rim when measured this morning. There have been no significant changes in seismicity levels across the volcano. Early this morning, sharp deflationary tilt began at the summit.

Summit Observations: Sharp deflationary ground tilt has been measured at the summit since early this morning. The level of the lava lake dropped slightly, and was measured at 30 m (98 ft) below the Overlook crater rim. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php. Summit tremor continues to fluctuate in response to variations in lava lake spattering and earthquakes occurred at normal, background rates. Summit sulfur dioxide emission rates remain high.

Slight deflationary tilt was recorded by a nearby tiltmeter, mirroring the summit ground tilt. There was no significant change in East Rift Zone seismicity. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. Yesterday evening, the National Park reported delta collapse activity. Several large cracks had developed in the lava delta, running parallel to the coastline and spanning the width of the delta. These cracks increase the likelihood of a delta collapse.

Surface flows continue on the upper portion of the flow field, above the pali, as well as on the coastal plain. Observations from Monday's overflight, noted breakouts on the coastal plain within about 950 m (0.6 mi) of the base of the pali and 2.2 km (1.4 mi) from the gravel emergency route. Webcam images suggest similar conditions persist.

Ocean Entry Hazards: The ocean entry is a hazardous area. Hazards include walking on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris from sudden explosive interaction between lava and water.
