In this video students will get a great view as to what liquefaction is during an earthquake. This video comes from the 2011 earthquake in Japan. One of the cool things about this video is that you can actually see the earth shift as is grinds the dirt squeezing the water out causing the liquefaction.
Students will be able to witness some video captured during the 1989 Loma Prieta Earthquake. I use this video as part of my Daily Dose of Destruction series when teaching about the destructive power of earthquakes.
In this video students will gain a better understanding of what seismographs, seismometers and seismograms are. As students study earthquakes they can use some of this information to understand how scientists use use seismic data to discover where earthquakes are located. This science video also talks about the different types of earthquake waves, P, S, and Surface waves.
In this video your earth science students will be able to witness a compilation of video from the 2011 Japan earthquake. In this video students will see that building can sway as the earth moves. They get to see a little liquefaction. There is some video of the tsunami that occurred. Most of the video show how earthquakes can be destructive. I use this video as part of my Daily Dose of Destruction series during my earthquake unit.
In this video students get to hear and see a really rare volcanic eruption. These are silent killers called limnic eruptions. Limnic eruptions occur when a gas bubble builds up and then gets released poisoning the air all around. This video demonstrates how a limnic eruption killed nearly everyone in two different villages as carbon dioxide was released. I discuss a little bit about air density during this video as well.
During my unit on volcanoes I have the students do some research on some famous volcanoes. Mt. Vesuvius is one. This video shows a quick tour of the city of Pompeii and discusses how they made casts and molds of the victims of a very famous eruption.
I show this video when discussing pyroclastic flows. This is a pyroclastic flow that killed a few people in Japan a couple of years ago. It is pretty impressive video as people try to protect themselves and outrun the flow. I also get to discuss how even though there are many warnings of a pending volcanic eruption occurring, it doesn't always mean that there will be advanced warning.
I have actually been to the Arenal Volcano. It is a beautiful site. The volcano erupted sending down a pyroclastic cloud killing several villages in one of the towns close by. It then erupted off and on creating the steepest cone in the world. This video is a composite of many other videos showing the eruptions over time. It is a pretty cool video to watch. I actually skim through it but get a chance to show how one volcano can have multiple types of eruptions. I also mention that there are many hot springs near by. Some of which I got to swim in.
I show this volcano video when discussing cinder cone volcanoes. Paricutin erupted in the 1943 and erupted for 9 years afterward. It occurred on fairly flat land in a farmer's cornfield. This video is historical footage of the eruption.
