How can you and your government detect and predict a HAARP attack? With an induction magnetometer. A magnetometer measures electromagnetic disturbances in the magnetic field in Earth's upper atmosphere. It is not a seismometer which measure motions of the ground.
The magnetometer doesn't measure seismic activity it measures and records electromagnetic frequencies in the Earth's atmosphere. A magnetometer can be used as an early warning system as it records auroral activity that precedes a HAARP induced earthquake or weather modification occurrence.
