The unrest on Kīlauea’s Upper and Middle East Rift continues into September with moderately elevated earthquake rates, although the situation appears to have temporarily stabilized. Summit tiltmeters show little net change over the past week, while the magma body intruded near Maunaulu shows signs of continued filling, perhaps diverting the magma supply from the summit. Further downrift at Puʻu’ōʻō and beyond, only minor changes in ground tilt have been registered following the wave of ground swelling that swept east from Makaopuhi about a month ago.

Altogether, the situation remains dynamic but confined within Hawaiʻi Volcanoes National Park and poses no increased threat to people. Gas emissions are the volcanic hazard of present concern, and while emissions remain relatively low for the volcano around 75 tonnes of SO2 per day, these can still be of concern for sensitive individuals nearby. “Changes in the character and location of unrest can occur quickly, as can the potential for eruption, but there are no signs of imminent eruption at this time,” according to USGS-HVO.
