Since then, there have been 33 overflows from the north vent. Most of the overflows have lasted about 10-35 minutes and produced lava flows that traveled a few hundred meters (yards) from the vent. There were no overflows for about 20 hours from 7:44 a.m. HST yesterday to 3:36 a.m. HST this morning with 7 overflows since that time.  Many of the overflows were fed by vigorous fountains that rise 15-30 feet (5-10 meters) above the small 30-50 foot (10-15 meter) cone that has built up at the north vent. The north and south vents continued to glow strongly overnight and emitting nearly continuous flames. Glow from the west vent was sporadic and weak. Intermittent spatter bursts were also observed from the north vent last night between overflows. No other areas of incandescence were observed across the summit region last night.\u003C\/p\u003E\u003Cp\u003EContinuous tremor is the dominant seismic signal across the summit. There were ten small and shallow earthquakes located across the summit region in the past day. Six of these clustered around the \u0022outlet\u0022 area at the south end of Kaluapele, the summit caldera.\u003C\/p\u003E\u003Cp\u003ESummit tilt has inflated over the past day, with about 0.8 microradians of inflation recorded. The current total inflation since the end of episode 54 is about 16.8 microradians, which is about 4 microradians greater than what was lost during episode 54 fountaining.\u003C\/p\u003E\u003Cp\u003EDuring inter-episode pauses, the sulfur dioxide (SO\u003Csub\u003E2\u003C\/sub\u003E) emission rate from the summit typically varies between 1,000 and 5,000 tonnes per day.

In addition, the north, south, and west vents continued to glow, and the south and north vent emitted nearly continuous flames. Intermittent spatter was visible from the north vent during pauses in overflow activity. Strong continuous tremor dominates the seismic signal within the summit. Forecast windows for this episode can no longer be modeled due to the irregular changes in inflation and deflation. Since reaching a peak inflation of 16 microradians (UWD tilt post episode 54) on Wednesday September 16, the summit deflated about 2.3 microradians as the new lava flows from vents 1-6 ceased. Slow inflation (recorded on the UWD tiltmeter) started Thursday September 17 and has now reached 16.8 microradians since the end of episode 54, with 0.8 microradians of inflation recorded in the past 24 hours. Current eruptive activity is focused on the north vent, which has produced the last 11 high fountain events (episodes 44-54). However, it is not possible to say with certainty that this activity will lead to the onset of another fountain event at this time, although conditions remain favorable.\u003C\/p\u003E\u003Cp\u003EBecause the summit system remains active and highly pressurized, the two most likely possibilities are that activity continues at the north-south-west vent complex, or it activates another existing weak crack system in the summit region. Neither of these events are likely to produce a strong seismic precursor, so the alert levels have been left at ORANGE\/WATCH as the volcano continues to \u003Ca href=\u0022https:\/\/www.usgs.gov\/programs\/VHP\/alert-level-system\u0022\u003E\u0022exhibit heightened unrest with an increased potential for eruption\u0022\u003C\/a\u003E.

Since then, there have been 33 overflows from the north vent. Most of the overflows have lasted about 10-35 minutes and produced lava flows that traveled a few hundred meters (yards) from the vent. There were no overflows for about 20 hours from 7:44 a.m. HST yesterday to 3:36 a.m. HST this morning with 7 overflows since that time.  Many of the overflows were fed by vigorous fountains that rise 15-30 feet (5-10 meters) above the small 30-50 foot (10-15 meter) cone that has built up at the north vent. The north and south vents continued to glow strongly overnight and emitting nearly continuous flames. Glow from the west vent was sporadic and weak. Intermittent spatter bursts were also observed from the north vent last night between overflows. No other areas of incandescence were observed across the summit region last night.\u003C\/p\u003E\u003Cp\u003EContinuous tremor is the dominant seismic signal across the summit. There were ten small and shallow earthquakes located across the summit region in the past day. Six of these clustered around the \u0022outlet\u0022 area at the south end of Kaluapele, the summit caldera.\u003C\/p\u003E\u003Cp\u003ESummit tilt has inflated over the past day, with about 0.8 microradians of inflation recorded. The current total inflation since the end of episode 54 is about 16.8 microradians, which is about 4 microradians greater than what was lost during episode 54 fountaining.\u003C\/p\u003E\u003Cp\u003EDuring inter-episode pauses, the sulfur dioxide (SO\u003Csub\u003E2\u003C\/sub\u003E) emission rate from the summit typically varies between 1,000 and 5,000 tonnes per day.

In addition, the north, south, and west vents continued to glow, and the south and north vent emitted nearly continuous flames. Intermittent spatter was visible from the north vent during pauses in overflow activity. Strong continuous tremor dominates the seismic signal within the summit. Forecast windows for this episode can no longer be modeled due to the irregular changes in inflation and deflation. Since reaching a peak inflation of 16 microradians (UWD tilt post episode 54) on Wednesday September 16, the summit deflated about 2.3 microradians as the new lava flows from vents 1-6 ceased. Slow inflation (recorded on the UWD tiltmeter) started Thursday September 17 and has now reached 16.8 microradians since the end of episode 54, with 0.8 microradians of inflation recorded in the past 24 hours. Current eruptive activity is focused on the north vent, which has produced the last 11 high fountain events (episodes 44-54). However, it is not possible to say with certainty that this activity will lead to the onset of another fountain event at this time, although conditions remain favorable.\u003C\/p\u003E\u003Cp\u003EBecause the summit system remains active and highly pressurized, the two most likely possibilities are that activity continues at the north-south-west vent complex, or it activates another existing weak crack system in the summit region. Neither of these events are likely to produce a strong seismic precursor, so the alert levels have been left at ORANGE\/WATCH as the volcano continues to \u003Ca href=\u0022https:\/\/www.usgs.gov\/programs\/VHP\/alert-level-system\u0022\u003E\u0022exhibit heightened unrest with an increased potential for eruption\u0022\u003C\/a\u003E.

Since then, there have been 33 overflows from the north vent. Most of the overflows have lasted about 10-35 minutes and produced lava flows that traveled a few hundred meters (yards) from the vent. There were no overflows for about 20 hours from 7:44 a.m. HST yesterday to 3:36 a.m. HST this morning with 7 overflows since that time.  Many of the overflows were fed by vigorous fountains that rise 15-30 feet (5-10 meters) above the small 30-50 foot (10-15 meter) cone that has built up at the north vent. The north and south vents continued to glow strongly overnight and emitting nearly continuous flames. Glow from the west vent was sporadic and weak. Intermittent spatter bursts were also observed from the north vent last night between overflows. No other areas of incandescence were observed across the summit region last night.\u003C\/p\u003E\u003Cp\u003EContinuous tremor is the dominant seismic signal across the summit. There were ten small and shallow earthquakes located across the summit region in the past day. Six of these clustered around the \u0022outlet\u0022 area at the south end of Kaluapele, the summit caldera.\u003C\/p\u003E\u003Cp\u003ESummit tilt has inflated over the past day, with about 0.8 microradians of inflation recorded. The current total inflation since the end of episode 54 is about 16.8 microradians, which is about 4 microradians greater than what was lost during episode 54 fountaining.\u003C\/p\u003E\u003Cp\u003EDuring inter-episode pauses, the sulfur dioxide (SO\u003Csub\u003E2\u003C\/sub\u003E) emission rate from the summit typically varies between 1,000 and 5,000 tonnes per day.

In addition, the north, south, and west vents continued to glow, and the south and north vent emitted nearly continuous flames. Intermittent spatter was visible from the north vent during pauses in overflow activity. Strong continuous tremor dominates the seismic signal within the summit. Forecast windows for this episode can no longer be modeled due to the irregular changes in inflation and deflation. Since reaching a peak inflation of 16 microradians (UWD tilt post episode 54) on Wednesday September 16, the summit deflated about 2.3 microradians as the new lava flows from vents 1-6 ceased. Slow inflation (recorded on the UWD tiltmeter) started Thursday September 17 and has now reached 16.8 microradians since the end of episode 54, with 0.8 microradians of inflation recorded in the past 24 hours. Current eruptive activity is focused on the north vent, which has produced the last 11 high fountain events (episodes 44-54). However, it is not possible to say with certainty that this activity will lead to the onset of another fountain event at this time, although conditions remain favorable.\u003C\/p\u003E\u003Cp\u003EBecause the summit system remains active and highly pressurized, the two most likely possibilities are that activity continues at the north-south-west vent complex, or it activates another existing weak crack system in the summit region. Neither of these events are likely to produce a strong seismic precursor, so the alert levels have been left at ORANGE\/WATCH as the volcano continues to \u003Ca href=\u0022https:\/\/www.usgs.gov\/programs\/VHP\/alert-level-system\u0022\u003E\u0022exhibit heightened unrest with an increased potential for eruption\u0022\u003C\/a\u003E.
