#Hawaii Volcanic Activity

Volcano Watch is a weekly article and activity update written by US Geological Survey Hawaiian Volcano Observatory scientists and affiliates. Today’s article is written by RCUH geophysicist Maddie Hawk. 

The USGS Hawaiian Volcano Observatory has a number of seismometers in place across Kīlauea Volcano for monitoring volcanic processes and active fault movements. When magma is not moving within or erupting from Kīlauea, the oceanic microseisms appear on seismometers as a repeating and unchanged signal.

Early Wednesday morning, just before 1 a.m. on March 13, houses in east Hawai`i began to shake. Without a doubt, it was an earthquake.
