 Week 11 - Plate Tectonics


"Plate Tectonics may have started 400 million years earlier than we thought." is an article I found online about the possibilities of finding the age of the Earth's movement. Harvard geologists have measured the Honeyeater Basalt in Western Australia. They found by tracking the changes in the orientation of the lava, they are able to determine how the craton is moving. I thought it was pretty interesting in that we are always looking for ways to find evidence from the past.

Week 7 - Mass Wasting, Streams & Flooding HURRICANE HARVEY  I moved to central Texas after Hurricane Harvey hit the Gulf Coast. Houston (which is 1 1/2 hrs away from where I am) was one of the cities that took a huge hit in rainfall that caused severe flooding. A few things I found, Hurricane Harvey is the first major hurricane (winds greater than 110 MPH) rainfall measured in feet inundated coastal Texas in millions. Hurricane Harvey originated from a westward-moving tropical wave that emerged from Africa over the eastern Atlantic ocean.  Highest wind speed:  134 MPH Date:  August 17, 2017 - September 2, 2017 Category:  Tropical Depression (NHC/CPHC), Category 4 Hurricane Damage: estimated $125 billion I work at the airport in College Station/Bryan for American Airlines and the two airports in Houston and another airport in Beaumont were severely impacted by Hurricane Harvey. We were almost called to travel down there to assist at the airports. As for the w...

 Week 03 - Volcanic eruptions  A-L-O-H-A my fellow geologists! When you look at all the photos from your latest vacation or your family member or friend's last adventure do you ever think about a VOLCANO in Hawaii! If you haven't greeted the beautiful atmosphere or took a quick swim in the blue, clear ocean. Let's go for a little field trip! Mauna Loa (mah-oo-nah low-ah) is one of the five volcanoes that surround the islands of Hawaii. It is the largest subaerial volcano in both mass and volume. " Mauna Loa is comprised of the main summit caldera called Moku‘āweoweo and three rift zones to the northeast, northwest, and southwest .  Eruptions of Mauna Loa most often will begin in the summit caldera and then later migrate to a rift zone.  Mauna Loa has erupted 33 times since 1843— averaging once every five years. Over a longer period of time, the past 3,000 years, it's estimated to have erupted once every six years. We are currently in the volcano's longest quie...
