The agency’s weekly article recounts activity since 2018, including a December 2020 intrusion and a summit eruption that lasted about five months.

- USGS says the 2020 intrusion was the first sign of shallow magma movement at Kīlauea since the 2018 eruption ended.

Why it matters: The article places a recent caldera intrusion amid Kīlauea’s ongoing episodic summit lava fountaining, while noting that intrusions and eruptions are not unusual there.
