<p>To first answer this question; we must first look into "What can turn off Amaterasu"</p>

<ul>
<li>Amaterasu lasts 7 days and 7 nights</li>
<li>Amaterasu can be turned off by the user's will</li>
<li>Amaterasu is turned off when the material projected onto it has been burned</li>
</ul>

<p>With that being said, Amaterasu 2 will not "burn out" Amaterasu 1, they will simply burn for 7 days and 7 nights before they will both cease to exist.<br>
