I have noticed that the amplitude numbers in the ShakeNet app seem to be bigger than on swarm when a filter is applied (by a factor of ~3). Raw data seems ok. For example, the same event with the 0.7-2.0 Hz filter:
Hello kpjamro,
You know, this is the second time that we have noticed something like this in the last 24h! What a coincidence!
We are investigating this, also comparing our results to what the free python obspy package shows, and we’ll update you on our findings as soon as we’re done.
Thank you for reporting this.
