How do I get the amplitude profile of an earthquake Signal?

I have El-Centro data. Using wavelet analysis,I have reconstructed the signal, I need to get a smooth plot of the amplitude profile which envelopes the Accel vs Time graph. Any idea how I should go about it?
TIA

Another option is to use the Hilbert transform, as described in Envelope Extraction Using the Analytic Signal (Signal Processing Toolbox).

Yes, according to the documentation.
I’ve used it on some of my signals, and it works.
