The Apolaki Caldera is the world's largest volcanic caldera at 150 kilometers diameter. It is situated within the Benham Rise (Philippine Rise) and was discovered in 2019 by Filipino marine geophysicist Jenny Anne Barretto and her team. The name "Apolaki" means "giant lord" in Filipino and refers to a god of sun and war in some Philippine mythologies and indigenous folk religions. The volcano has been inactive for millions of years. #APOLAKI #caldera #volcano #digitalcreator | Re Gina

This morning, around 2:20 AM, a new #Kilauea eruption began within Kaluapele (the summit caldera). It was caught on camera by #HVO's B2cam. Images taken by the webcam were compiled into this timelapse video that shows lava fountains feeding lava flows across the caldera floor. The eruption has stabilized within the crater and there are no immediate threats to infrastructure. More photos and videos are in HVO's photo and video chronology: https://www.usgs.gov/observatories/hvo/news/photo-and-vide
