Located in the central Pacific Ocean, Big Island is the southeastern-most island in the US state of Hawaii and, as its name suggests, the largest in the archipelago. Having formed above a magma hotspot in the Pacific plate, Hawaii has some of the world\u2019s largest active volcanoes. One of these is Kilauea on the southeastern side of Big Island.<\/p>\n
This Copernicus Sentinel-2 image from 3 September 2025 shows a lava lake approximately 2.5 km in length, inside the main crater of Kilauea. Following an eruptive episode on 2 September, lava fountains reached about 100\u00a0m high and lava flowed from multiple vents in the main crater.<\/p>\n
Although the image has been processed in natural colour, the mission\u2019s shortwave infrared channels, which detect heat sources, were also used to highlight the fiery lava flowing from the crater in orange and red. Plumes of smoke can also be seen leaking from the crater.<\/p>\n
The current eruptive phase began on 23 December 2024 and continued into 2025 with repeated episodes of lava spewing into the air and flowing down the volcano. Signs of older eruptions are visible on the southern flanks of the crater as dark brown flows of solidified lava towards the coast.<\/p>\n
Unlike the event pictured here, which was confined within the summit\u2019s crater and posed little threat to the nearby communities, the eruption that began in May 2018 was one of the most destructive in Kilauea\u2019s recorded history. It destroyed more than 600 homes and produced about 320 000 Olympic-sized swimming pools\u2019 worth of lava that reshaped the landscape.<\/p>\n
As we see in the image, the volcanic rock creates a rugged terrain, which contrasts with the surrounding lush vegetation and fields.\u00a0In particular, light green and yellow areas north of the main crater correspond to human settlements, roads and plantations.<\/p>\n
Big Island, like the other Hawaiian islands, has tropical forests from the combination of fertile volcanic soil and heavy rainfall. The clouds, visible throughout the image, form when the Pacific trade winds blow across the mountains in the middle of the ocean.<\/p>\n
Satellite missions such as Copernicus Sentinel-2 are an excellent way to monitor volcanic eruptions, as they can image smoke plumes, lava flows, mudslides and ground fissures and can be used to help assess damage.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
