While these earthquakes are not impacting Kilauea, one of the world’s most active volcanoes, it has been intermittently erupting since Dec. 23.

According to the latest update from the Hawaiian Volcano Observatory, the intensity of these eruptions, so-called “lava fountaining,” has strengthened after weakening in the days after the initial eruption.

Webcam observations by USGS scientists show that these eruptions are currently confined to its crater.
