6.0 Magnitude EQ – South Sandwich Islands

At approximately 05:53:45 UTC on Sunday, January 22nd, an earthquake based on water struck at a depth of 9.8 km (6.1 miles) in the South Sandwich Islands region, 138 km (85 miles) E of Visokoi Island, South Sandwich Islands. Coords: 56.645°S, 24.944°W

Due to the size and whereabouts of such a quake, there is no tsunami threat from this earthquake.

United States Geological Survey – The event has been reviewed by a seismologist and confirmed, at present, to be a 6.0 magnitude earthquake at a depth of 9.8 km, originally reviewed as a 6.2, but demoted while this was being typed.  The European Mediterranean Seismology Agency has not yet had the earthquake’s parameters reviewed.

Seismic activity increases down South

On the 12th there was a lot of action South of Africa, with a 4.94.8 and another 4.9 in a 30 minute period. 12 hours later a 5.5 strikes the same area, and then after some more, a 5.3. All of those quakes were supposedly registered at 10km in depth. Then once again to the South, on the 13th, from 57 to 64 km depths, a 5.1 and a 5.2 strike the South Sandwich Islands region. Then once more, on the 15th, two earthquakes based on water near the South Shetland Islands near Antarctica struck at depths estimated at 10km for the first, a 6.6 magnitude earthquake, and 14km for the second, a 6.2 quake. More recently on the other side of the pole, on the 19th, a 5.9 quake struck West of South Island, New Zealand.

  1. My feeling is that this activity is still the plates settling after the Japan quake. You should also remember that all we are seeing is the quakes they publish. Due to the remote nature of the area many ‘mystery’ quakes go unpublished because there is insufficient data to determine the epicentre.

    These are often quakes with magnitudes as high as Mag 5.
