Two times series of northern motion from GPS station KAEP

The top panel is from before the 2018 Kīlauea eruption and shows two steps corresponding to slow slip events (SSEs).  The bottom panel is from after 2018 and shows no evidence of step-like motion indicative of SSEs, although the slight curve does suggest that a post-eruption increase in seaward motion is slowly returning to background.  The inset photo is of the KAEP instrument site, on Kīlauea’s south flank.
