Vivid new satellite photos of Anak Krakatau are providing our first cloud-free glimpse of the island volcano that triggered a devastating tsunami in Indonesia late last month. As the photos show, a gaping lagoon now appears where a 339.85m-high volcanic mountain once stood.

Volunteer rescuers working on beaches along Sundra Strait have rescued more than 30 stranded sea turtles, following the Indonesian tsunami that has killed hundreds of people, the Guardian reports.
In 2011, a colossal tsunami set off by a magnitude 9.0 earthquake slammed into the eastern shores of Japan. Not long afterwards, some of the 1.5 million tons of floating debris created by the waves, from buoys and boats to entire fishing docks, began washing up along America’s northwest Pacific coast.
Indonesia is reeling from a series of geologically-triggered disasters. While it was still assessing the fallout from August’s deadly Lombok earthquake, a major earthquake on September 28 triggered a tsunami that slammed into Central Sulawesi. According to the latest UN reports, this disaster robbed at least 2010 people of their lives, with 700 still reported missing.
The tsunami that struck Indonesia's Sulawesi island and killed at least 1400 people sadly won't be the last. Human populations will continue to live along coastlines in tectonically active parts of the world, tsunamis will continue to occur, and people will continue to die.
Four people are missing and nearly a dozen homes were flooded after a rare tsunami struck the west coast of Greenland on Saturday. Initial reports attributed the giant wave to a magnitude four earthquake, but speculation is emerging that the highly-localised tsunami was actually produced by a massive landslide.
Mars once featured a vast ocean that covered its northern hemisphere. New evidence suggests this Martian sea experienced at least two "mega-tsunamis" that were triggered by meteor impacts. Traces of these cataclysmic events can still be seen on the Martian surface, and they could still contain traces of ancient life.
The threat of a tsunami is a very real thing for much of the Pacific coastline, yet many cities in the US haven't taken specific infrastructural measures to ensure their residents are safe when they happen. A new building in Washington will have the first purpose-built tsunami shelter in the country, offering accessible safety in a second-story room.
Didn't it seem to you that the ground was exceptionally shaky last month? That there were reports on big earthquakes happening somewhere pretty much every week? It wasn't just your imagination: April produced a higher-than-normal number of moderate-to-large earthquakes, and you can see it for yourself.
Waves come from the wind so tsunamis, which are basically bigger waves, must come from more wind, right? Not exactly. This cute animation explains that though normal waves are formed from above, tsunamis come from below from volcanic eruptions, landslides and earthquakes. They're the real monsters of the sea.
Deploying the improved infrastructure that will hopefully help prevent future tsunamis from devastating Japan is an expensive endeavour. So researchers are developing new and cheaper ways to protect the country, like this innovative floodgate that deploys automatically when waters come rushing in -- no power or human operators required.
