( perhaps a shallow sea at the time?)
This would’ve caused heated hollow steam air pockets under the surface that would shift in layers as it cooled. Water filled caverns would collapse as they dried up forming the heart shape in the smaller crater?
One curious thing, six distinct cone volcanos, perfectly round cinder mounds, two of which have volcanic calderas. They could almost be mistaken for impact craters…
