While the USGS site offers JPEG versions of ShakeMaps, the .jpg files inevitably contain lossy compression artifacts. Since the USGS site offers PostScript versions of the same (downloadable in .ps.zip form), then it's possible to extract and then convert .ps files to PNG with the GIMP GhostScript plugin. The requirements are that 'Text antialiasing' is strong, and 'Graphic antialiasing' is set to 'none' during .ps import.
