Time-series of earthquakes and deformation—Kīlauea summit intrusion

Time-series plots of earthquake hourly counts in Kīlauea summit and tilt at the Sandhill station, southwest of Kīlauea’s caldera

Detailed Description

Time-series plots of earthquake hourly counts in Kīlauea summit region (top) and tilt at the Sandhill station located southwest of Kīlauea’s caldera (bottom). These plots show the increase in activity associated with the recent south caldera intrusion at the summit of Kīlauea. The increase in the earthquake counts correlates to the influx of magma pressurizing the volcano. Increasing tilt indicates accumulation of magma. These USGS time-series plots show data from August 22 to 31, 2021.
