The seismic station 2.9 km W of the volcano was restored on 4 July and recorded small sub-continuous tremors.
Some discrete high-frequency volcanic earthquakes were also recorded on most days. Sulfur dioxide emissions were 100 tonnes per day on 4 July. According to the United Nations in Papua New Guinea 7,318 people remained displaced within seven sites because of the 26 June eruption.
