© IMOThe quakes in Bárðarbunga are marked with green stars.
According to the Seismic Monitoring System of the Icelandic Meteorological Office the first quake, a 2.8 magnitude quake was detected at 23:34 at a depth of 4.1 km (2.5 mi), followed by a second 2.7 magnitude quake 17 seconds later at a depth of 2.5 km (1.6 mi). Nine minutes past midnight a magnitude 4 quake was then detected at a depth of 1.1 km (0.7 mi). At the exact same moment a second, 4.6 magnitude quake was detected closer to the center of the caldera, at a depth of 7.1 km (4.4 mi). These were then followed by a third sharp 3.5 magnitude quake at a depth of 2.2 km (1.4 mi).
Comment: One wonders the increasing activity of Earth's undersea volcanoes coupled with the cooling above ground is partly responsible for the migrating ice bergs, and perhaps their unexpected shapes:
- Gigantic iceberg A-68 that broke off Larsen ice shelf blocked by dense sea ice, surprising scientists
- Stargate? Saturn sprouts another weird hexagon
- Arctic lake mysteriously disappears in Novaya Zemlya, Russia
- 'Perfectoid geometry' may be the secret that links numbers and shapes
- Stem cells organize using geometry as a guide
- Evidence of volcanic eruptions under Antarctic Ice
- Antarctica is even colder than scientists thought
