Failure forecast

How to read this

When there is no forecast, this panel shows each epoch's step in the zone, with the steps the supervising agent confirmed as ground motion in blue. For creep-type failures, one divided by velocity falls along a straight line and reaches zero at failure (Fukuzono 1985). Dots are the measured epochs after the onset of acceleration, the dashed line is the fit, the vertical line is its intercept, and the shaded band is the forecast window from a bootstrap of the fit plus the spread of three fitting methods. The forecast is always a window, never a single time.

Displacement

How to read this

Each dot is one epoch: the median displacement of the zone's valid subsets, with a band of one standard deviation estimated from the median absolute deviation (1.4826 times the MAD). A flat line is a quiet slope, a straight rise is steady creep, a curve bending upward is acceleration. Unusable epochs (blind, blurred, camera event) leave gaps; nothing is filled in.

Camera

The latest usable camera epoch with measured displacement: grey is no motion, deeper blue is more, arrows show direction

Agent investigations

    No events yet. When the instrument raises one (acceleration, a jump, a camera event, a quality drop), the agent re-runs OpenCV on the stored images and records each call here.
