1. A seismic sensor module, comprising:
- sensing elements arranged in a plurality of axes to detect seismic signals in a plurality of respective directions; and
a processor to;
receive data from the sensing elements;
determine inclinations of the axes with respect to a particular orientation;
use the determined inclinations to combine the data received from the sensing elements to derive tilt-corrected seismic data for the particular orientation, wherein the processor is to combine the data received from the sensing elements by using the determined inclinations to determine a noise leaked into a seismic signal along the particular orientation due to seismic signals propagating in other orientations.

Abstract
A seismic sensor module includes sensing elements arranged in a plurality of axes to detect seismic signals in a plurality of respective directions, and a processor to receive data from the sensing elements and to determine inclinations of the axes with respect to a particular orientation. The determined inclinations are used to combine the data received from the sensing elements to derive tilt-corrected seismic data for the particular orientation.
