Volcanic eruption triggers series of quakes that cracked up and fissured the island of Ambrym, Vanuatu

2

On December 15, 2018, a volcanic eruption on Vanuatu’s Ambrym Island has sparked a series of earthquakes that have opened cracks around the island.

This video by John Tasso features the new fissure that opened up on the Ambrym volcano two days ago:

The volcanic eruption triggered a swarm of tremors – the strongest was  a M5.6 earthquake – which has caused some houses to collapse.

Quakes ranged from M2.2 to M5.6 and were very shallow. This is the reason why they have caused a lot of cracks in the ground and in buildings, mostly on the south east part of Ambrym.

Here some pictures of the large fissures:
