HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, June 26, 2017, 8:54 AM HST (Monday, June 26, 2017, 18:54 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: No significant change. Kīlauea Volcano continues to erupt at the summit and at Puʻuʻōʻō vent on the East Rift Zone. The episode 61g lava flow from Puʻuʻōʻō is entering the ocean at Kamokuna. Surface flows are active above the pali, but pose no threat to nearby communities. The summit lava lake level is rising in concert with inflationary tilt. The lake surface is about 30 m (100 ft) below the floor of Halemaʻumaʻu this morning. There have been no significant changes in seismicity levels or ground deformation trends across the volcano.

Summit Observations: Tiltmeters at Kīlauea's recorded continuing inflation, and the lava lake level rose to about 30 m (100 ft.) below the rim of the Overlook Vent. Webcam views of the lava lake can be found at: http://hvo.wr.usgs.gov/cams/region_kism.php. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high.

Puʻuʻōʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The tiltmeter near Puʻuʻōʻō crater recorded modest inflationary tilt 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. Park visitors reported that a portion of the lava delta at the ocean entry collapsed yesterday around noon. Near Puʻuʻōʻō, flows continue on the upper portion of the flow field. These flows do not pose any threat to nearby communities at this time.

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. This occurred most recently on May 3. 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.

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: No significant change. Kīlauea Volcano continues to erupt at the summit and at the Puʻuʻōʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻuʻōʻō is entering the ocean at Kamokuna. Surface flows are active above the pali. These lava flows pose no threat to nearby communities. The summit lava lake surface is approximately 22 m (72 ft.) below the floor of Halemaʻumaʻu this morning. Tilt at the summit has turned to deflation so we expect that the lava level will be dropping today. There have been no significant changes in seismicity levels or ground deformation trends across the volcano.

Summit Observations: Tiltmeters at Kīlauea's summit recorded a switch from DI inflation to deflation this morning at about 6 AM. The lava lake surface was measured at approximately 22 m (72 ft.) below the rim of the Overlook Vent this morning. Webcam views of the lava lake can be found at: http://hvo.wr.usgs.gov/cams/region_kism.php. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high.

Puʻuʻōʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The tiltmeter near Puʻuʻōʻō crater has been recording tilt that mimics summit tilt, with a delay; it has not yet switched to deflationary tilt as of 8:45 am. 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. The new lava delta is approximately 3.2 acres in size, extending about 100 m (328 ft.) out from the sea cliff. At Puʻuʻōʻō, flows continue on the upper portion of the flow field. None of these flows poses any threat to nearby communities at this time.

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. This occurred most recently on May 3. 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.

Tuesday, June 20, 2017, 8:50 AM HST (Tuesday, June 20, 2017, 18:50 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: No significant change. Kīlauea Volcano continues to erupt at the summit and the Puʻuʻōʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻuʻōʻō in the East Rift Zone is entering the ocean at Kamokuna. Surface flows are active above the pali. These lava flows pose no threat to nearby communities at this time. The lava lake surface is approximately 25 m (82 ft.) below the floor of Halemaʻumaʻu. Low rates of ground deformation and seismicity continue across the volcano.

Summit Observations: Tiltmeters at Kīlauea's summit are recording inflationary tilt. The lava lake surface is approximately 25 m (82 ft.) below the rim of the Overlook Vent, as of this morning. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high.

Puʻuʻōʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The tiltmeter is recording inflationary tilt trend. 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. The new lava delta is approximately 3.2 acres in size, extending about 100 m (328 ft.) out from the sea cliff. At Puʻuʻōʻō, flows continue on the upper portion of the flow field. None of these flows poses any threat to nearby communities at this time.

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. This occurred most recently on May 3. 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.
