Bug with events about seedlink_plotter HOT 7 OPEN

If I change
neries_emsc = Client("EMSC")
to
neries_emsc = Client("IRIS")
I don't have the error. But I don't know if IRIS catalogue should be used instead of EMSC...

from seedlink_plotter.

obspy/obspy#883

from seedlink_plotter.

The problem is the minmagnitude argument for EMSC

from seedlink_plotter.

I propose to switch to IRIS instead of EMSC

from seedlink_plotter.

#31

from seedlink_plotter.

I have this error

FDSNException: Bad request. If you think your request was valid please contact the developers.

But the script still continues.. right? Just shows that message on stderr? Because the get_events() call seems to be properly encased in a try/except.

from seedlink_plotter.

Could it be this was just a temporary problem?

I just did a quick comparison of what catalog data is returned for today (i.e. 12 hours backwards from realtime) with M>2 for each of the FDSNWS end points and it looks like in general EMSC catalog might be the best option for near-realtime data. ISC might be an obvious choice but it is not able to give data for near-realtime (newest event 4 hours behind realtime), seems like.

from obspy import UTCDateTime
from obspy.clients.fdsn import Client
from obspy.clients.fdsn.header import URL_MAPPINGS

t = UTCDateTime(2018, 4, 10)

for key in URL_MAPPINGS.keys():
    client = Client(key)
    try:
        cat = client.get_events(starttime=t, minmagnitude=2)
    except:
        continue
    cat.events = sorted(cat.events, key=lambda e: e.origins[0].time)
    print key
    print cat
    print ''
    cat.plot(outfile='/tmp/events/%s.png' % key, show=False)
