Kilauea , Hawai :

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:
Eruptive activity continues at Kilauea Volcano’s summit and East Rift Zone. The 61G lava flow extending southeast of Pu’u ‘O’o towards the ocean remains active but poses no threat to nearby communities. As of Friday, the flow tip was about ~730 m (0.45 miles) from the ocean. The lava lake at Halema’uma’u Crater continues to circulate and intermittently spatter. Seismicity and deformation rates throughout the volcano remain at background levels.


Vigorous spattering from Kilauea Volcano’s summit lava lake was visible from the Jaggar Museum Overlook in Hawai’i Volcanoes National Park as of this afternoon. The lava lake surface, measured at 25 m (82 ft) below the vent rim this morning, was high enough for the spattering to be seen from afar.

Summit Observations:
The lava lake within the Halema’uma’u Overlook crater remains active. The depth to the lake was measured at 21.5 m (70 ft) below the crater rim, Friday. Tiltmeters at Kilauea’s summit recorded a slight deflationary tilt. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate ranged from 3,700 to 7,300 metric tons/day.



The collapse of a lava tube’s roof, creating an enormous skylight roughly 30 feet in diameter and 30-40 feet deep, illustrates one of the hazards of volcanic activity. This is a view looking northeast, and the direction of lava movement is from left to right.

Pu’u ‘O’o Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater. There were no significant changes in seismicity over the past 24 hours. The tilt excursion is due to heavy rainfall. The sulfur dioxide emission rate from all East Rift Zone vents on July 22 was about 500 metric tons/day.



Lava Flow Observations:
The 61G lava flow extending southeast of Pu’u ‘O’o towards the coastal plain on Kilauea’s south flank remains active. On Friday, the flow tip was active and breakouts were active within a few hundred meters (yards) upslope. The flow was approximately 600 m (0.4 miles) from the coastal emergency road and 730 m (0.45 miles) from the ocean. Areas of incandescence remain visible in overnight webcam views of the active lava flow field, marking lava tube skylights and areas of active lava on the pali and along the flow as it extends towards the coast.

Head of Post PGA Egon, Yosef Suryanto said the appeal for safety, follows after the thick smell of sulfur wafted from a radius of three kilometers from the mountain. Suryanto said that Mount Egon, still maintains the status of the alert level two.



The village closest to the mountain is the village of Egon Gahar, District Mapitara, which is only three kilometers away.
« In recent days, Mount Egon often had thick smoke and volcanic earthquakes have been recorded on a small scale, and the smell of sulfur by the citizens, » said Suryanto told reporters on Saturday (07/23/2016).
According Suryanto, if it erupts, PVMBG will raise the status of being vigilant to a radius of five kilometers, and residents in the three-kilometer radius will be evacuated to a safer place.


« Until now the status is still at alert level two, and we recommend that communities around Mount Egon and visitors or tourists, not to engage in activities within a radius of one and a half kilometers from the summit, » he said.
To note, the two-level alert status was issued by the local government last February. This status is still maintained until today because of the activity of the mountain is still happening.
Until now, residents who live near the mountain did not know the status of alert, due to not having been informed by the government.
