obspy.imaging.beachball.MomentTensor

class MomentTensor(*args)[source]

Bases: object

A moment tensor.

>>> a = MomentTensor(1, 1, 0, 0, 0, -1, 26)
>>> b = MomentTensor(np.array([1, 1, 0, 0, 0, -1]), 26)
>>> c = MomentTensor(np.array([[1, 0, 0], [0, 1, -1], [0, -1, 0]]), 26)
>>> a.mt
array([[ 1,  0,  0],
       [ 0,  1, -1],
       [ 0, -1,  0]])
>>> b.yz
-1
>>> a.expo
26

Special Methods

MomentTensor.__delattr__(name, /): Implement delattr(self, name).

MomentTensor.__dir__(): Default dir() implementation.

MomentTensor.__eq__(value, /): Return self==value.

MomentTensor.__format__(format_spec, /): Default object formatter.

MomentTensor.__ge__(value, /): Return self>=value.

MomentTensor.__getattribute__(name, /): Return getattr(self, name).

MomentTensor.__gt__(value, /): Return self>value.

MomentTensor.__hash__(): Return hash(self).

MomentTensor.__init__(*args)[source]

MomentTensor.__init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

MomentTensor.__le__(value, /): Return self<=value.

MomentTensor.__lt__(value, /): Return self<value.

MomentTensor.__ne__(value, /): Return self!=value.

MomentTensor.__new__(**kwargs)

MomentTensor.__reduce__(): Helper for pickle.

MomentTensor.__reduce_ex__(protocol, /): Helper for pickle.

MomentTensor.__repr__(): Return repr(self).

MomentTensor.__setattr__(name, value, /): Implement setattr(self, name, value).

MomentTensor.__sizeof__(): Size of object in memory, in bytes.

MomentTensor.__str__(): Return str(self).

MomentTensor.__subclasshook__()

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).
