Fig. 2: Point-source earthquake prediction.
From: Rapid wavefield forecasting for earthquake early warning via deep sequence to sequence learning
a Snapshots of Y-component velocity at T = 7.4, 11.75, 16.1, and 20.45 s for (top) ground truth, (middle) predictions from densely and regularly sampled input, and (bottom) predictions from sparsely and irregularly sampled input (triangles denote sensor locations). b Map of predicted peak ground velocity (PGV) values and c corresponding PGV prediction errors. d Map of predicted PGV arrival time (TPGV) values and e corresponding TPGV prediction errors. Errors are computed as the difference between predicted and ground-truth values; positive errors indicate overestimation, and negative errors indicate underestimation.
