A slight inflationary trend near and east of Puʻu ʻŌʻō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.

Computer programs known as Geographic Information Systems (GIS) have been the preferred tool of USGS cartographers for many years. Using commercial GIS software, the user creates a stack of “layers,” such as labels, roads, and political boundaries that together form a map.

The 2018 summit collapse and lower East Rift Zone eruption at Kīlauea Volcano were dramatic and, for many Island of Hawaiʻi residents, tragic events. As with all eruptive crises, these events offered exceptional opportunities to learn more about how volcanoes work and to answer some “bigger picture” questions.
