I haven't done the research, but is @rolltide incorrect in his assertion that you can get certain data from USGS (such as magnitude, depth, and location)? That information is available on the USGS website.
Or are people down-voting him/her because of the claim of making your own seismoter? (rolltitde did misspel seismometer).
I downvoted it for "Twitter lol".
1) The "lol" is unnecessary and juvenile
2) The statement indicates that either using Twitter should somehow be obvious, or that the poster is not taking the posed question seriously
On balance, it pulls the level of discourse down, which is my (and the proper) criteria for a downvote.
I would appreciate that you not censor other people comments over such trivial things.
Because it's really annoying to everyone else. And thus rude.
so you can learn a lot from downvote censored comments on this site
Edit: for example...
“A 3.7 magnitude earthquake occurred 0mi WSW of Compton, CA. Details: http://eqbot.com/2iV Map: http://eqbot.com/2ii”
You just dont get magnitude, depth and location data
You can also make your own seismoter, its not complicated but everything makes them go off
