The 2018 eruption on Kīlauea’s lower East Rift Zone spewed around a billion cubic yards of lava into Puna. From the moment the eruption began, samples of lava were collected and rapidly analyzed by a team of USGS Hawaiian Volcano Observatory and University of Hawaiʻi at Hilo scientists.

Kīlauea Volcano's summit has been in an eruptive pause since the 2018 events ended over a year ago. Nevertheless, it remains a dynamic place. Ongoing inflation and seismicity indicate that the summit magma chamber is gradually recharging.

2018 and 2019 were years of profound change at Kīlauea Volcano and the USGS Hawaiian Volcano Observatory. Devastation caused by the largest lower East Rift Zone eruption and summit collapse in at least 200 years resulted in many transitions for island residents, including HVO.

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making.

On October 17, 1989, at 5:04 pm a magnitude M6.9 earthquake struck near Loma Prieta, California. It was a tragic reminder of the destructive power of earthquakes. However, it was also a watershed moment in seismic research. 30 years later, we revisit the earthquake through the eyes of the scientists who experienced it. And studied it. These are their stories.
