Lassen Volcanic’s geology is very interesting. The terrain has been influenced from many different natural occurrences from 25,000 to 18,000 years ago. Referring back to the May 22, 1915 eruption, the active volcano created a great deal of devastation and depressions; known as the Devastated Area. The devastation caused has an area of three square miles. Volcanoes are common at Lassen. In fact, Lassen is home to all four types of volcanoes, which are shield, cinder cone, plug dome, and…

Obsidian can be found in countries where eruptions have occurred such as the United States, Turkey, Scotland, Peru, New Zealand, Mexico, Kenya, Japan, Italy, Iceland, Guatemala, El Salvador, Greece, Georgia, Chile, Canada, Azerbaijan, Armenia, and Argentina. Obsidian is volcanic lava that has cooled and is often referred to as volcanic glass. The name obsidian originated from a Roman named Obsius, a man who discovered a gemstone very similar in nature to obsidian. Its black, glassy, shiny and…

Volcanos have been shaping and changing the way we live and how we feel for thousands of years. When you think of a volcano, you think of a destructive natural force of obsolete menace. You are right, but these volcanos can change environments and people in so many good ways. From creating rich soil for farming and beautiful environments, it almost seems that these powerful and seemingly indestructible parts of nature can make good out of bad. Okay, so lets’ look at the elephant in the room;…

I’m finally home. It has been a difficult week at work and it is nice to feel the long shag carpet between my toes when I walk into my living room. That and the light blue walls are warm and inviting. Give me five minutes in my well-worn easy chair and all the stress of work will be a distant memory. As I was relaxing and flipping through the TV channels I saw that a volcano near my house may erupt. Not only is it going to erupt, but it is predicted to be so big it may bring another ice age…

Most of Costa Rica is dominated by the Sierra Madre mountains, literally fractured into individual ranges and valleys by violent volcanic eruptions over eons of time. Guatemala, except for the coastal areas, is a mountainous country of rolling hills, plateaus, deep river valleys, and numerous volcanoes – some still active.Speaking of volcanoes , Costa Rica’s most active one, located in the Tilaran Mountains erupts in some measure almost every day. To the southeast, the Poas, Barva, Irazu and…

In this set of materials, the reading passage tells us about the three types of rock, and the listening passage explains the additional usage of sedimentary rock, which is describing as a third rock in the reading passage. The reading passage informs us about the characteristics of the three rocks. The most common rock is Igneous rock which means fire. The example of it is granite. By cooling and solidification of lava, igneous rock will be formed, and this makes up approximately 64.7% of the…

This week I learned about the three different types of volcanoes and the types of volcanic hazards associated with each type of volcano. This information is important to me because now I understand the hazards associated with living in certain parts of the country that have volcanoes. I understand that the volcanoes found in Hawaii (Shield volcanoes) erupt differently and pose different dangers than the volcanoes in the Cascade Mountain Range (Composite volcanoes). Since I live in Portland,…

Erta- Ale, is today the longest continually erupting volcano on the planet. It is pretty much a lake of lava that has been molten for over 100 years. These same volcanic forces are what created Ethiopia’s highlands. Seventy million years ago, Ethiopia’s land was just flat and deep terrestrial land. It wasn’t until molten lava rose from the Earth’s core and crated a huge dome of rock 500 miles wide: the roof of Africa. The summit is about three miles high and are home to some very…
