Sedimentological evidence and archaeological data show that huge tsunami hit the coast of today’s Sultanate of Oman around 1000 CE; the tsunami was almost 50 feet (15 m) tall and was caused by a strong earthquake in the Makran subduction zone, a giant fault that slants beneath the Arabian Sea coast of Pakistan and Iran.

A series of false-color images capturing the repeated flaking of red clouds from the Great Red Spot in the Spring of 2019. In the earliest image, the flaking is predominant on the east side of the giant red vortex. The flake then breaks off from the Great Red Spot, but a new flake starts to detach in the fifth image.
