Fig. 2: Change of seismicity rate near latitudes 34°N and 44°N.
From: Change of deep subduction seismicity after a large megathrust earthquake
a Location of the earthquakes color-coded with depth. They correspond to the 200 closest earthquakes of the two black stars. b Cumulative number of earthquakes with time after declustering normalized at Tohoku-oki, for 34°N (blue) and 44°N latitude (red). Note the change of slope at the time of the Tohoku-oki earthquake, with λb the slope before and λa, the slope after the megathrust earthquake. c probability density function (pdf) of the rate change (see Methods). A rate change r < 1, =1, >1, means decrease, no change and increase, respectively. The probability of change at Tohoku-oki is maximum with rmax = 0.47 at 34°N (blue) and rmax = 1.3 at 44°N latitude (red).
