Fig. 3From: Long-term slow slip events with and without tremor activation in the Bungo Channel and Hyuganada, southwest JapanObserved (red) and synthetic (blue) displacement vectors with error ellipses (one standard deviation) for the two SSEs. a, b The SSE in 2015–2016 and c, d the 2018–2019 sequence. a, c Horizontal components and b, d vertical components. The difference between the averages of coordinates for each of the first and last 15 days of the analyzed time period is calculated for each component at each stationBack to article page
