# How can I change 'References' in capital letters

I am writing a paper with 'article' style.

I just put a reference list by:

\begin{thebibliography}{5}
.....
\end{thebibliography}


It creates 'References' section. I, however, want to have section 'REFERENCE'.

P.S. I want to submit the paper to Seismological research letter electronic seismologist.

You should use the following definition before \begin{document}:
\def\refname{REFERENCE}
