In recent years data processing methods have greatly improved, so the deep moonquakes were newly classified and assigned to nests by Yosio Nakamura of the University of Texas, Galveston. At present another attempt has been started to locate the nests with new methods again. There is hope,
To determine Far Side Candidates the method by Martin Knapmeyer named LOCSMITH is used, which was designed to find all possible hypocenters for as sparse data as available from the Apollo missions. Preliminary results were published at the EGU in Vienna, 2008.
To achieve good new locations, the events of one nest firstly have to be freed from errors that are in the seismograms due to noise and transmission errors, which was done in a certain order of steps. Noise was reduced by a frequency filter, and the resulting events of one nest were stacked to reduce the signal to noise ratio. After this, the arrival times of the seismic waves of the events were picked. By now a couple of nests have been relocated.
