Mesmerising 4k footage of molten lava bubbling in a lava lake

Footage I filmed of the lava lake inside the Marum crater which is on the Ambrym island in Vanuatu. (Copyright) At the time of uploading this video (filmed several years ago), this lake had been covered in thousands of tonnes of basalt rock after a 'volcanic event' destroyed parts of the crater wall and rim. However, I believe there is activity within the crater that might be early stages of the lava lake re-emerging. The lava seen here is approx 1200 degrees celsius at its hottest. I filmed this while on an expedition with @geoffmackley and at this time held the unofficial record of the most descents inside the crater to the crater floor.
