The Big Island is getting bigger, thanks to lava flowing into the ocean from the Kilauea volcano in Hawaii.

The big picture: U.S. Geological Survey (USGS) geologist Janet Babb told Axios that since May, eruptions have created a "lava delta" spanning 825 acres, with between 50 and 150 cubic meters of lava entering the ocean every second. The volcano has been erupting continuously since 1983, but the recent rate is unprecedented; until May, the land added by lava totaled just 500 acres.

Go deeper: In a new report on the landmass additions, the USGS explains that some lava deltas have a hard time solidifying and staying attached to land because there is a steep offshore slope. But this time, the area is far less steep, allowing the delta to expand and persist for longer.

Lava deltas are "notoriously unstable," Babb said, so the USGS puts out a new map every day as the terrain continues to change, and as topographic maps are updated (which happens less frequently) they will reflect the additions as well.

Newly released transcripts of bodycam footage from the Minneapolis Police Department show that George Floyd told officers he could not breathe more than 20 times in the moments leading up to his death.

Why it matters: Floyd's killing sparked a national wave of Black Lives Matter protests and an ongoing reckoning over systemic racism in the United States. The transcripts "offer one the most thorough and dramatic accounts" before Floyd's death, The New York Times writes.

Fighting the coronavirus infodemic

An "infodemic" of misinformation and disinformation has helped cripple the response to the novel coronavirus.

Why it matters: High-powered social media accelerates the spread of lies and political polarization that motivates people to believe them. Unless the public health sphere can effectively counter misinformation, not even an effective vaccine may be enough to end the pandemic.
