# -*- coding: utf-8 -*- obspy.neries - NERIES Web service client for ObsPy ================================================== The obspy.neries package contains a client for the Seismic Data Portal (http://www.seismicportal.eu) which was developed under the European Commission-funded NERIES project. The Portal provides a single point of access to diverse, distributed European earthquake data provided in a unique joint initiative by observatories and research institutes in and around Europe.

Basic Usage ----------- (1) :meth:`~obspy.neries.client.Client.getEvents()`: The following example illustrates how to request all earthquakes of a magnitude of >=9 in the year 2004.
>>> from obspy.neries import Client >>> client = Client(user='test@obspy.org') >>> events = client.getEvents(min_datetime="2004-01-01", ... max_datetime="2005-01-01", ... min_magnitude=9) >>> len(events) 1 >>> events #doctest: +SKIP [{'author': u'CSEM', 'event_id': u'20041226_0000148', 'origin_id': 127773, 'longitude': 95.724, 'datetime': UTCDateTime(2004, 12, 26, 0, 58, 50), 'depth': -10.0, 'magnitude': 9.3, 'magnitude_type': u'mw', 'latitude': 3.498, 'flynn_region': u'OFF W COAST OF NORTHERN SUMATRA'}]
(2) :meth:`~obspy.neries.client.Client.getLatestEvents()`: Returns only the latest earthquakes.
>>> from obspy.neries import Client >>> client = Client(user='test@obspy.org') >>> events = client.getLatestEvents(num=5, format='list') >>> len(events) 5 >>> events[0] #doctest: +SKIP [{'author': u'CSEM', 'event_id': u'20041226_0000148', 'origin_id': 127773, 'longitude': 95.724, 'datetime': u'2004-12-26T00:58:50Z', 'depth': -10.0, 'magnitude': 9.3, 'magnitude_type': u'mw', 'latitude': 3.498, 'flynn_region': u'OFF W COAST OF NORTHERN SUMATRA'}]
(3) :meth:`~obspy.neries.client.Client.getEventDetail()`: Returns additional information for each event by a given event_id.
>>> from obspy.neries import Client >>> client = Client(user='test@obspy.org') >>> result = client.getEventDetail("20041226_0000148", 'list') >>> len(result) # Number of calculated origins 11 >>> result[0] # Details about first calculated origin #doctest: +SKIP {'author': u'CSEM', 'event_id': u'20041226_0000148', 'origin_id': 127773, 'longitude': 95.724, 'datetime': UTCDateTime(2004, 12, 26, 0, 58, 50), 'depth': -10.0, 'magnitude': 9.3, 'magnitude_type': u'mw', 'latitude': 3.498, 'flynn_region': u'OFF W COAST OF NORTHERN SUMATRA'}
(4) :meth:`~obspy.neries.client.Client.getWaveform()`: Wraps a NERIES Web service build on top of the ArcLink protocol. Here we give a small example how to fetch and display waveforms.
>>> from obspy.neries import Client >>> from obspy import UTCDateTime >>> client = Client(user='test@obspy.org') >>> dt = UTCDateTime("2009-08-20 04:03:12") >>> st = client.getWaveform("BW", "RJOB", "", "EH*", dt - 3, dt + 15) >>> st.plot() #doctest: +SKIP
.. plot::
from obspy.neries import Client from obspy import UTCDateTime client = Client(user='test@obspy.org') dt = UTCDateTime("2009-08-20 04:03:12") st = client.getWaveform("BW", "RJOB", "", "EH*", dt - 3, dt + 15) st.plot()
(5) :meth:`~obspy.neries.client.Client.getTravelTimes()`: Wraps a Taup Web service, an utility to compute arrival times using a few default velocity models such as ``'iasp91'``, ``'ak135'`` or ``'qdt'``.
>>> from obspy.neries import Client >>> client = Client(user='test@obspy.org') >>> locations = [(48.0, 12.0), (48.1, 12.0)] >>> result = client.getTravelTimes(latitude=20.0, longitude=20.0, ... depth=10.0, locations=locations, ... model='iasp91') >>> len(result) 2 >>> result[0] # doctest: +SKIP {'P': 356981.13561726053, 'S': 646841.5619481194} """
