(BIVN)<\/strong> \u2013 The ongoing eruption of K\u012blauea within Hawai\u02bbi Volcanoes National Park is currently paused, with earthquakes and deflation observed at the summit. <\/p>\n

The expected start of the next episode of high lava fountaining has been pushed back. The USGS Hawaiian Volcano Observatory says \u201cthe forecast window for episode 46, based on tilt data, suggests that lava fountaining will occur again sometime between Sunday, May 3 and Thursday, May 7.\u201d The Observatory says the window may be adjusted based on continuing observations.\u00a0<\/p>\n

The U\u0113kahuna tiltmeter is currently recording slight deflationary tilt. The same tiltmeter has measured a total of 9.0 microradians of inflationary tilt since the end of episode 45 on April 23rd.<\/p>\n

\u201cFluctuations in tilt are normal during eruptive pauses,\u201d the Observatory says.\u00a0<\/p>\n

Scientists have also measured increased earthquake activity at the summit over the past day.<\/p>\n

On Wednesday morning, the Observatory reported 96 small earthquakes were recorded, primarily within Halema\u02bbuma\u02bbu crater and south\/southwest of the caldera. The earthquakes were all less than magnitude 2.0.<\/p>\n

Seismic tremor continues with regular pulses, scientists say.\u00a0<\/p>\n

\u201cConsistent glow was observed from both vents on webcams overnight, although glow was significantly brighter in the south vent,\u201d the Observatory wrote on Wednesday. \u201cBoth vents produced occasional flames, likely caused by the ignition of volcanic gases escaping the vent.\u201d\u00a0<\/p>\n

With the eruption paused, sulfur dioxide emission rates are likely varying within a typical range of 1,000 to 5,000 tonnes per day, scientists say.\u00a0<\/p>\n

The USGS Volcano Alert Level for K\u012blauea remains at ADVISORY, and the Aviation Color Code is YELLOW.\u00a0<\/p>\n<\/div>\n
