HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Sunday, November 19, 2017, 8:47 AM HST (Sunday, November 19, 2017, 18:47 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 Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas on the coastal plain. These lava flows pose no threat to nearby communities at this time. The lava lake surface is approximately 40 m (131 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; over the last 24 hours the volcano experienced a cycle of inflation-deflation and now inflationary tilt. The lava lake surface is approximately 40 m (131 ft.) below the rim of the Overlook Vent, based on web camera images. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high. Current webcam views are here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō 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 a deflationary 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. Based on overnight web camera images, surface lava flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas on the coastal plain. A field crew visited the ocean entry, on Friday, and found that activity at the ocean entry stopped and activity on the lava delta was in a dramatic state of decline; very sluggish, pasty flows in a few random spots and very little to no degassing in the usual places. None of these flows poses any threat to nearby communities at this time. At Kamokuna delta this morning, there is no plume is visible in webcam images: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

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.

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 its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. In concert with summit deflation, the level of the lava lake has dropped overnight. The episode 61g lava flow is still producing scattered surface flow activity on the pali and the coastal plain. These flows pose no threat to nearby communities at this time. There have been no significant changes in ground deformation or seismicity rates across the volcano.

Summit Observations: After weeks of little change, deflationary tilt at the summit began early yesterday afternoon and continues this morning. In concert, the level of the summit lava lake has dropped overnight as much as 10 m (33 ft). Sulfur dioxide gas emission rates continue to be high. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering. Current webcam views are here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: In the past day, seismic activity has continued at normal, background rates. The tiltmeter on Puʻu ʻŌʻō cone showed no significant change. Webcams showed persistent glow from a small lava pond on the west side of the crater overnight. The sulfur dioxide emission rates from the East Rift Zone vents have been steady over the past several months, and remain significantly lower than the summit emissions.

Lava Flow Observations: The episode 61g flows do not pose a threat to nearby communities at this time. Lava from the episode 61g flow continues to flow down the from the vent to the Kamokuna delta. Webcam views indicate that scattered breakouts remain active above the pali and on the coastal plain. At Kamokuna delta this morning, there is no plume is visible in webcam images: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

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 is still producing scattered surface flow activity, and there is weak ocean entry over the past 24 hours. These flows pose no threat to nearby communities at this time. This morning, the height of the lava lake at Kīlauea's summit, was measured at 31 m (102 ft) below the rim of Overlook crater. There have been no significant changes in ground deformation or seismicity rates across the volcano.

Summit Observations: Slight deflationary tilt was recorded by summit tiltmeters over the past day, with little change in the lava lake level. This morning, the lake level was measured at 31 m (102 ft) below the rim of Overlook crater. Sulfur dioxide gas emission rates continue to be high. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering. Webcam views can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: In the past day, seismic activity has continued at normal, background rates. The tiltmeter on Puʻu ʻŌʻō cone showed no significant change over the past day. Webcams showed persistent glow from a small lava pond on the west side of the crater overnight. The sulfur dioxide emission rates from the East Rift Zone vents have been steady over the past several months, and remain significantly lower than the summit emissions.

Lava Flow Observations: The episode 61g flows do not pose a threat to nearby communities at this time. Lava from the episode 61g flow continues to flow down the from the vent to the Kamokuna delta. Webcam views indicate that scattered breakouts remain active above the pali and on the coastal plain. A breakout was active on the pali this morning. At Kamokuna delta, lava has entered the sea over the past 24 hours but no plume is visible on webcam images. Webcam views of the 61G lava flows can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

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.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, November 13, 2017, 9:01 AM HST (Monday, November 13, 2017, 19:01 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 is still producing scattered surface flow activity, and has re-entered the ocean in the past 24 hours, producing a very weak and intermittent plume. These flows pose no threat to nearby communities at this time. This morning, the height of the lava lake at Kīlauea's summit, was roughly 33 m (108 ft) below the rim of Overlook crater, based on webcam images. There have been no significant changes in ground deformation or seismicity rates across the volcano.

Summit Observations: Slight deflationary tilt was recorded by summit tiltmeters over the past day, with little change in the lava lake level. This morning, based on webcam images, the lake level was roughly 33 m (108 ft) below the rim of Overlook crater. Sulfur dioxide gas emission rates continue to be high. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering. Webcam views have been restored and can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

Puʻu ʻŌʻō Observations: In the past day, seismic activity has continued at normal, background rates. The tiltmeter on Puʻu ʻŌʻō cone showed no significant change over the past day. Webcams showed persistent glow from a small lava pond on the west side of the crater overnight. The sulfur dioxide emission rates from the East Rift Zone vents have been steady over the past several months, and remain significantly lower than the summit emissions.

Lava Flow Observations: The episode 61g flows do not pose a threat to nearby communities at this time. Lava from the episode 61g flow continues to flow down the from the vent towards Kamokuna delta. Webcam views indicate that scattered breakouts remain active above the pali and on the coastal plain. Two breakouts were active on the pali last night and into the morning. At Kamokuna delta, lava has entered the sea within the past 24 hours and a weak, intermittent plume has been seen on webcam images. Webcam views of the 61G lava flows can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html.

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.
