Maria Seton, University of Sydney; Joanne Whittaker, University of Tasmania, and Simon Williams, University of Sydney For most people, continents are Earth’s seven main large landmasses. But geoscientists have a different take on this. They look at the type of rock a feature is made of, rather than how much of its surface is above […]
On August 28, Stromboli volcano in Italy woke up a second time in this summer. Tourists decided to ride a boat near the erupting volcano – but the journey turned out to be “fun”: they had to escape from the wave of pyroclastic flow. The eruption did not lead to casualties and destruction, but the […]
The blockbuster movie Jurassic World: Fallen Kingdom (2018) involves more than just dinosaurs wreaking havoc. Humans are sent in to rescue some prehistoric critters on the volcanic island of Isla Nublar, and chaos soon begins. The volcano erupts, and everyone runs away as a roiling cloud called a pyroclastic flow approaches. At one point the […]
Mount Stromboli, one of the three active volcanoes in Italy (others being Mount Etna on Sicily – continuous activity, and Mount Vesuvius, near Naples – last erupted in 1944), has been in almost continuous eruption for the past 2,000 years. The last eruption took place on 3 July 2019. The exact moment of the event […]
According to research published in the journal Earth and Planetary Science Letters, Earth’s oldest rock (which is 4.1 billion years old) has been found in an Apollo 14 sample from the Moon. If confirmed, it’s an amazing discovery.
Mount Etna, Europe’s most active volcano (also one of the most active volcanoes in the world) is sliding into the Ionian Sea at rates of centimeters per year. If part of it falls into the sea, it could create horrible mega-tsunamis that would devastate the eastern Mediterranean shores.
The universe is shrouded in mystery, and part of this mystery involves our own little planet. Although there has been countless research, the scientists and experts have only been able to barely scratch the surface (both figuratively and literally) in case of planet earth. However, the studies in Seismology have allowed us to gather sufficient […]
During the STS-68 mission (September 30-October 11, 1994), the crew members of Space Shuttle Endeavour used a 70 mm camera to photograph Klyuchevskaya Sopka (also known as Kliuchevskoi), a stratovolcano, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. The eruption was new when this photo was taken. […]
I stumbled upon an amazing web page showing what did ancient Earth look like. On the “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient […]
Earth’s outer shell is divided into multiple plates that slowly glide over the mantle. The movement of these plates slowly changes Earth’s surface over time by merging, or separating, continents. 250 million years from now, consistent with the supercontinent cycle (see notes 1), there will be a possible future supercontinent called Pangaea Ultima. Hypothesized by […]
