Between January 15 and 18, 2025, Hawaii’s Kīlauea volcano entered a new eruptive phase, marking the fourth eruption since December 23, 2024. This renewed activity captivated volcanologists and the public alike, offering a dramatic display of nature’s power.

The Hawaiian Volcano Observatory confirmed that the eruption was confined to the Halemaʻumaʻu crater within the Kīlauea summit caldera. A striking aspect of this episode was the presence of episodic lava fountaining, a rare phenomenon that has not been seen in Kīlauea’s recent eruptions.

This image, captured by the Copernicus Sentinel-2 satellite on January 21, 2025, reveals the lingering thermal signature of cooling lava from the eruption.

The Copernicus Sentinel satellites, operated by the European Space Agency, continue to play a vital role in monitoring volcanic activity worldwide, providing invaluable data to researchers and authorities. These insights are crucial for improving safety measures for communities living in the shadow of volcanoes.
