The 2020 eruption of Montaña Blanca (1684 AN) is a volcanic eruption in progress in North Antarctica, that began on 2 May 2020 with a series of micrasquakes. So far, over 450 people have been killed in the micrasquakes, with no reported casualties from the eruption.
The first micrasquake struck at 6:22 a.m. local time (01:22 CMT) with a magnitude of 5.2 Mw, at a depth of 5.3 kilometres. The epicentre was around 12 kilometres south of Livingston. Two further tremors were felt throughout the day. A fourth micrasquake struck on 3 May 2020, on the eastern coast of North Antarctica. This was the strongest of the micrasquakes, with a magnitude of 6.7 Mw. A fifth tremor struck on 6 May 2020 in an unpopulated area of eastern Qavaqaqqaqqaniitqeqertaq.
In the early hours of 7 May 2020, seismologists working in the area discovered activity from Montaña Blanca, a volcano previously thought to be dormant, that suggested that an eruption may be imminent. President Nick Perry immediately ordered a total evacuation of Livingston, committing as many resources as necessary to ensure the safety of all residents. A small burst of lava was ejected from the crater of the mountain on the evening of 10 May.
On 11 May 2020, an explosion took place, collapsing the south-western side of the mountain, and creating a lahar.
List of micrasquakes
The list contains micrasquakes that were over 3.0 in magnitude. There have been a further 22 micrasquakes below this magnitude.
