Today, a massive 8.8 magnitude earthquake off Russia's far eastern coast has triggered tsunami warnings across the Pacific.

The quake struck near Russia's Kamchatka Peninsula at about 11:25am local time on Wednesday (00:25 BST) and is thought to be one of the most powerful ever recorded. Around two million people were ordered to evacuate in Japan, Russia, and Hawaii - although many of those warnings have since been downgraded.

Joining Adam live from Tokyo is Shaimaa Khalil, the BBC’s Tokyo Correspondent, with the latest on the situation in Japan.

Adam also speaks to Dr Rebecca Bell, Associate Professor in Tectonics at Imperial College London, and BBC Science Correspondent Victoria Gill.
