Simple representation of a seismic event.

Functions

dump_events(events[, filename, stream, format])	Write events file.
load_events(filename[, format])	Read events file.

Classes

Event([lat, lon, north_shift, east_shift, ...])	Representation of a seismic event.
Tag(...)	Any str matching pattern '^([A-Za-z][A-Za-z0-9._]{0,128})(:([A-Za-z0-9._-]*))?$'.

class Tag(...) → str

Bases: StringPattern

Any str matching pattern '^([A-Za-z][A-Za-z0-9._]{0,128})(:([A-Za-z0-9._-]*))?$'.

class Event(lat=0.0, lon=0.0, north_shift=0.0, east_shift=0.0, time=0.0, name='', depth=None, elevation=None, magnitude=None, magnitude_type=None, region=None, load=None, loadf=None, catalog=None, moment_tensor=None, duration=None, tags=None, extras=None)

Representation of a seismic event.

♦ time

pyrocko.util.get_time_float (pyrocko.guts.Timestamp), default: str_to_time('1970-01-01 00:00:00')

Origin time (UTC system timestamp) [s].

♦ depth

float, optional

Depth below surface [m].

♦ name

str, optional, default: ''

Event identifier.

♦ magnitude

float, optional

Magnitude of the event.

♦ magnitude_type

str, optional

Magnitude type magnitude is given in.

♦ region

str, optional

Source region.

♦ catalog

str, optional

Name of catalog that lists this event.

♦ moment_tensor

pyrocko.moment_tensor.MomentTensor, optional

Moment tensor of the event.

♦ duration

float, optional

Source duration [s].

♦ tags

list of str (Tag) objects, default: []

Auxiliary tags.

♦ extras

dict of pyrocko.guts.Any objects, default: {}

Additional user defined event attributes. The given values must be YAML-serializable.

get_hash()

Get a pseudo-unique hash over the main attributes of the event.

The following attributes are hashed: time, lat, lon, depth, magnitude, catalog, name, region.

Returns:

URL-safe base64 encoded SHA1 hash.

load_events(filename, format='detect')

Read events file.

Parameters:

• filename – name of file as str

• format – file format: 'detect', 'basic', or 'yaml'

Returns:

list of Event objects

dump_events(events, filename=None, stream=None, format='basic')

Write events file.

Parameters:

• events – list of Event objects

• filename – name of file as str

• format – file format: 'basic', or 'yaml'
