Fig. 2.

Time series of (A) lake volume (V) and discharge (Q); (B) rate of change of discharge (dQ/dt); (C) surface uplift (Z) and rate of uplift (dZ/dt); and (D) normalized rms (RMS) seismic amplitude, and normalized cumulative energy at Lake 028. Dashed lines at 1245 UTC and 0140 UTC mark the timing of preflight and postflight drainage UAV surveys shown in Fig. 1 B and C. Shading marks the 3 phases of rapid drainage outlined in the discussion. A version of this figure cropped to the time of rapid discharge is available as part of Movie S1.
