Electronic Supplement to
The 2016 Mw 6.7 Imphal Earthquake in the Indo-Burman Range: A Case of Continuing Intraplate Deformation within the Subducted Slab

by Revathy M. Parameswaran and Kusala Rajendran

This electronic supplement contains figures of broadband seismic station distribution and alternate source model for the 2016 Mw 6.7 Imphal event. Figure S1 shows the station distribution, whereas Figure S2 depicts the source model for the Imphal earthquake sourced at 20 km depth.


Figures

Figure S1. The distribution of broadband seismic stations used for teleseismic moment inversion.

Figure S2 (a–d). The source model for the 2016 Mw 6.7 Imphal event at a focal depth of 20 km. (a) Moment of 0.151 × 1020 N·m released in two bursts. (b) A right-lateral strike-slip solution with a slight oblique component. (c) Slip distribution: random slip vector direction that does not make a clear physical sense. (d) Waveforms matches. The thicker trace is the observed waveform, whereas the thinner one is the synthesized one. On the left side of each trace and its synthetic is the following information: first line is the station code; second line indicates whether the trace is a P wave or an SH wave followed by the peak-to-peak amplitude in micrometers; and third line gives us the epicentral distance and the azimuth of the station from the epicenter. (e) Waveform matches for the source model of the 2016 Mw 6.7 Imphal event at a focal depth of 20 km. Legends are the same as in (d). (f) Waveform matches for the source model of the 2016 Mw 6.7 Imphal event at a focal depth of 20 km. Legends are the same as in (d).
