Siberian Traps likely triggered end-Permian mass extinction

Around 252 million years ago more than 96 percent of marine species and 70 percent of land species disappeared in a geological instant. This event the so-called end-Permian mass extinction or more commonly known as, "The Great Dying" remains the most severe extinction event in Earth's history, but its direct cause has remained a mystery. Scientists suspect massive volcanic activity in an area of Russia called The Siberian Traps may have had a role in the Great Dying by raising the air and sea temperatures and releasing toxic amounts of greenhouse gases into the atmosphere of a very short period […]

Pacific Northwest Earthquakes—3 Types (Educational)

The Pacific Northwest is host to 3 types of tectonic earthquakes : Magnitude nine Cascadia megathrust quakes. Magnitude 6.5 to 7 deep earthquakes, and Shallow crustal-fault earthquakes withmagnitudes as much as 7.5. What motives them? We can exhibit how we can show how subduction of the Juan deFuca plate; basin & range extension, invasion of crustal blocks from California, and the resistance of the Canadian crustal buttresscombine to provide these earthquakes. We by using watching at Western North Americasactive plate boundaries The San Andreas Fault is a strike-slip change into fault zone alongwhich the Pacific Plate is sliding northwest at […]

Top 10 Deadliest Volcano Eruptions

Hey YouTube, Jim here! Welcome to Top10Archive! Mother Nature has proven time and time again that she’s a force to be respected. Beneath the Earth’s crust, molten rock threatens to burst through thin layers of the planet and flow across the surface, leveling everything in its path. While some volcanic activity leaves a wake of minimal damage, others impact a region so badly that they earned a spot on this Top 10 Deadliest Volcanic Eruptions. Before we get started, help us out by hitting that like button, and be sure to leave us a comment because we're always looking to […]

Volcanic Activity and Plate Motions

>> Hi, everyone. We're going to look in this animation at how the movements of the Earth's plates controls volcanic activity on the Earth. Let's look first at what's called continental rift volcanism. Now, in places where forces are causing the Earth's plates to stretch, especially in the continents, a couple of different things can happen. In this part of the animation, you can see there's what's called a rift valley where the crust is ripped apart and it sinks down to form a valley. That's kind of like the East African Rift Valley, or much of the Western United […]

World’s largest shake table reveals how earthquakes damage wood-framed buildings

Now we have been working for many decades to strengthen the performance of buildings underneath seismic loading. This can be a collaborative task with the japanese study team that has been conducting significant scale shake desk exams on the E-security facility. They’ve been conducting full scale assessments on two three-story wood buildings, traditional of urban environments in Tokyo. E-safety is the most important 3D shake desk on this planet to habits full scale exams on structures.Which you could have a entire building with each element. That you could subject the building to an actual, recorded earthquake. The superb intention for […]

Hawaii’s Kilauea Volcano – Behind the News

JACK EVANS: For the past couple of weeks, this river of red-hot rock has been causing chaos in the streets of Hawaii. MAN: I think it's faster than a turtle can move.

The lava is coming from Kilauea, a volcano on Hawaii's Big Island, which is home to these guys. Aloha, BTN. I'm Fiona. Aloha, BTN. My name is Sebastian. I go to the Volcano School of Arts & Sciences. It's about, like, maybe a four-minute […]

Space Volcanoes – Shelf Life 360

>>DENTON EBEL, CURATOR: For centuries, people wondered if there were volcanoes on the Moon. When people looked at the Moon with telescopes, they saw, “Aha! There’s these big round things.” At the time, it was not understood that impacts make craters that to the untrained eye might look like volcanoes. >> MISSION CONTROL: Apollo 11, this is Houston, over. >>EBEL: The rocks that the Apollo astronauts brought back unlocked the secrets of the Moon. Turns out, they’re a lot like the basaltic rocks that we’d find in Iceland, or in Hawaii. So, we know that the Moon was volcanically active […]
