Mizarai is a meteorite impact crater in Druskininkai municipality, Lithuania. The crater is not exposed to the surface and the site now hosts Mizarai village. The crater is about 5 km (3.1 mi) in diameter and about 250 m (820 ft) in depth. It was created by an asteroid, estimated 300 m (980 ft) in diameter,[1] 500 ± 20[2] or 570 ± 50[3] million years ago (Cambrian or Neoproterozoic). The asteroid hit basement rock and shattered it up to 1.3 km (0.81 mi) deep.[4] It was later buried under various sediments. Mizarai crater was discovered by Gediminas Motuza during an international seismic survey Eurobridge, which reached depths of 90–100 km (56–62 mi).[5]
