HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Wednesday, October 18, 2017, 8:22 AM HST (Wednesday, October 18, 2017, 18:22 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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit changed little over the past day and was last measured at about 40 m (131 ft) below the Overlook crater rim. Low rates of ground deformation and seismic activity persist across the volcano.

Summit Observations: The lava lake at Kīlauea's summit continues to be active; its height has not changed much since it was last measured at 40 m (131 ft) below the rim of the Overlook crater on Monday afternoon. No significant change in ground tilt was recorded by summit tiltmeters in the past 24 hours. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 2,500 and 5,400 metric tons/day over the past week. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: In the past day, seismic activity has continued at normal, background rates and no significant ground tilt was recorded by a nearby tiltmeter. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. Webcam views show persistent surface flow activity on the upper portion of the flow field and on the coastal plain, as well as renewed surface flow activity on the pali. At the ocean entry, intermittent lava flows over the cliff and onto the lava delta ("lavafalls") continue. Surface cracks on the lava delta that had been covered over, are propagating to the surface and beginning to be visible again. The episode 61g flows do not pose a 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. 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.

The height of the lava lake at Kīlauea's summit was last measured at about 40 m (131 ft) below the Overlook crater rim. Low rates of ground surface deformation and seismic activity persist across the volcano.

Summit Observations: The lava lake at Kīlauea's summit continues to be active; its height rose a little over the past day and was measured to be 40 m (131 ft) below the rim of the Overlook crater yesterday afternoon. Summit tiltmeters recorded minor amounts of inflationary tilt. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 3,200 and 5,400 metric tons/day over the past week. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: Low rates of ground deformation and low levels of seismic activity continue. Small apparent changes in tilt over the past several days on a nearby tiltmeter, are likely due to rainfall saturating the near surface. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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.

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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit has risen only slightly since it was last measured at about 44 m (144 ft) below the Overlook crater rim. Low rates of ground surface deformation and seismic activity persist across the volcano.

Summit Observations: Summit tiltmeters recorded minor inflationary tilt over the past day. Accordingly, the summit lava lake height has risen slightly since it was last measured at 44m (144 ft) below the rim of the Overlook crater on Saturday afternoon. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 2500 and 5400 metric tons/day over the past week. Seismicity rates were at normal, background levels, with tremor fluctuations related to lava lake spattering.

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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit continues to lower and was last measured at about 44 m (144 ft) below the Overlook crater rim. A M3.4 earthquake occurred yesterday evening, near the town of Volcano, but seismicity and deformation are otherwise occurring at normal rates.

Summit Observations: Summit tiltmeters recorded minor deflationary tilt for most of yesterday. Shaking from a M3.4 earthquake disrupted the tiltmeters momentarily and was responsible for a sharp step in the record from the UWE tiltmeter, displayed on the HVO website. The lava lake height continued to lower and was about 44 m (144 ft) below the adjacent Halemaʻumaʻu floor when measured yesterday afternoon. The M3.4 earthquake occurred at 8:36 PM HST yesterday, near the town of Volcano, and produced several smaller aftershocks. Seismicity otherwise occurred at normal rates. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 4500 and 5400 metric tons/day over the past week.

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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit continues to lower and was last measured at about 39 m (128 ft) below the Overook crater rim. Low rates of ground deformation and seismic activity persist across the volcano.

Summit Observations: Summit tiltmeters continued to record minor deflationary tilt for a second day, consistent with the deflation phase of a summit DI event (see definitions below). The lava lake height also continued to lower and was about 39 m (128 ft) below the adjacent Halemaʻumaʻu floor when measured yesterday evening. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 4500 and 5400 metric tons/day over the past week. Seismicity rates have been low, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: Low rates of ground deformation and low levels of seismic activity continue. Small apparent changes in tilt over the past two days on a nearby tiltmeter, are likely due to rainfall saturating the near surface. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. Poor weather made for poor visibility in webcam images over the past 24 hours. Nonetheless, they show continued surface flow activity on the upper portion of the flow field, on the pali, and on the coastal plain. Intermittent lava flows over the cliff and onto the lava delta ("lavafalls") have been reported. Recent activity has built up the height of the lava delta and covered over several large cracks, which previously had been visible on the surface. The episode 61g flows do not pose a 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.

Friday, October 13, 2017, 8:55 AM HST (Friday, October 13, 2017, 18:55 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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit has lowered slightly since its last measurement. Low rates of ground surface deformation and seismic activity persist across the volcano.

Summit Observations: Summit tiltmeters began to record minor deflationary tilt starting at about 4:30 PM HST yesterday, consistent with the beginning of a summit DI event (see definitions below). The lava lake height was about 35 m (115 ft) below the adjacent Halemaʻumaʻu floor when measured yesterday afternoon, but has lowered by roughly 5 m (16 ft) since deflationary tilt began. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 2500 and 5400 metric tons/day over the past week. Seismicity rates have been low, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: Low rates of ground deformation and low levels of seismic activity continue. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. Webcam views show continued surface flow activity on the upper portion of the flow field, southeast of Puʻu ʻŌʻō and on the coastal plain, as well as renewed surface flow activity on the pali. A plume was consistently present at the ocean entry yesterday, during daylight hours when it is detectable on webcam images, indicating continuing activity. Intermittent lava flows over the cliff and onto the lava delta ("lavafalls") have been reported on the western side of the ocean entry. Recent activity has built up the height of the lava delta and covered over several large cracks, which previously had been visible on the surface. The episode 61g flows do not pose a 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. 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
Thursday, October 12, 2017, 8:22 AM HST (Thursday, October 12, 2017, 18:22 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 entering the ocean at Kamokuna and producing scattered surface flow activity. These lava flows pose no threat to nearby communities at this time. The height of the lava lake at Kīlauea's summit changed very little over the past several days and is about 33 m (108 ft) below the Overlook crater rim. Low rates of ground surface deformations and seismic activity persist across the volcano.

Summit Observations: The lava lake within the Overlook crater remains active, with only minor fluctuations in its height over the past several days. Yesterday afternoon, it was again measured to be 33 m (108 ft) below the adjacent Halemaʻumaʻu floor and has changed little since that time. Summit tiltmeters have similarly shown insignificant changes in ground slope since completion of the most recent summit DI cycle on September 27. Measured sulfur dioxide gas emission rates continue to be high and ranged between roughly 2500 and 5400 metric tons/day over the past week. Seismicity rates have been low, with tremor fluctuations related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: Low rates of surface deformations and low levels of seismic activity continue. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. A plume was consistently present at the ocean entry yesterday, during daylight hours when it is detectable on webcam images, indicating continuing activity. Intermittent lava flows over the cliff and onto the lava delta ("lavafalls"), have been reported on the western side of the ocean entry. Recent activity has built up the height of the lava delta and covered over several large cracks, which previously had been visible on the surface. Webcam views show continued surface flow activity on the upper portion of the flow field, southeast of Puʻu ʻŌʻō and on the coastal plain. The episode 61g flows do not pose a 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. 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: Eruptions at Kīlauea Volcano continue with no apparent significant change. In the East Rift Zone, lava continues to enter the ocean at Kamokuna, and surface lava flow activity persists southeast of Puʻu ʻŌʻō on the upper portion of the 61g flow field and on the pali. Minor lava breakouts dot the coastal plain to the ocean entry. These lava flows pose no threat to nearby communities at this time. Lava lake activity continues at the summit of the volcano, with lava lake circulation and spattering, and minor fluctuations in the depth to the lava lake surface. Low rates of ground surface deformations and seismic activity persist across the volcano.

Summit Observations: The lava lake within the Overlook Vent continues to circulate and spatter, and webcam images show minor fluctuations in the depth to the lake surface through the course of the day. Monday evening, the level of the lake surface was measured at a depth of 34m (112ft) below the adjacent Halemaʻumaʻu floor. Summit tiltmeters have shown minor fluctuations since completion of the most recent summit DI cycle on September 27. Measured sulfur dioxide gas emission rates ranged between roughly 2500 and 4800 tonnes/day over the past week. Seismicity continues at low rates, with fluctuations in tremor amplitudes related to lava lake spattering.

Webcam views of the Halemaʻumaʻu lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Puʻu ʻŌʻō Observations: Low rates of surface deformations and low levels of seismic activity continue. Webcams show persistent glow from long-term sources within the crater and from a small lava pond on the west side of the crater. 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: Lava from the episode 61g flow continues to enter the ocean at Kamokuna. Webcam views suggest a decrease in the amount of lava visibly flowing down the pali, as well as a weakened plume at the ocean entry. Active surface lava flows also persist on the upper portion of the flow field southeast of Puʻu ʻŌʻō and toward the pali. The episode 61g flows do not pose a 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.
