Methods for estimating source time function (STF) and temporal variation of back-azimuth of the earthquake source using volmetric and multi-components strainmeter installed in Japan were developed. By applying those methods to the 2004 Sumatra-Andaman giant earthquake, the STF was estimated using volmetric strain records. The duration was about 700 s and the total moment was 5.2 × 1022 Nm, which were almost consistent with other results using seismometer records. Back-azimuth was successfully estimated by multi-components strain records, but the rupture propagation effect was not observed. Those methods were good tools for rapid estimation of giant earthquake source process and were useful for tsunami warnings.
