    AnnotationA microseismic method of monitoring fracturing operation or other microseismic events in hydrocarbon wells is described using the steps of obtaining multi-component signal recordings from a single monitoring well in the vicinity of a fracture or event; and rotating observed signals such that they become independent of at least one component of the moment tensor representing the source mechanism and performing an inversion of the rotated signals to determine the remaining components.
