Addison's Blog Issue #13 Coastal Hazards

 Canadian Geological Discoveries: Coastal Hazards

November 17, 2022


This week on Addison's blog will be focused on the danger zones in the coastal areas around Canada. Some of these include icebergs, sea ice, fog, and tsunamis. We already know a lot about tsunamis and flooding issues in the previous areas of the blog series, which is why we're going to discuss a few other details that weren't mentioned.

First off, there are problems within the coastline that can be extremely catastrophic. When ships set out to sea, they are met with some issues like fog. Fog isn't usually around until midnight when it's extremely cold. This is due to ocean temperature and air mass. Unfortunately for Canada, there is one type of problem that had casualties as a result. In 1914, about more than 1000 people had been killed in the St. Lawrence River in Rimouski Quebec. 

Another problem that seems to mess with people is icebergs, which are big pieces of ice drifted by the ocean current from the Arctic Circle. The average size of an iceberg would be around 90 meters above sea level. Not only can these humongous chunks of frozen water cause damage to any ship but can also bring financial disaster to industries. One of the hopes of avoiding these can be avoiding the ice pieces at all costs although some of them seem to have resistance against the heated temperatures in the summer.

The great news is due to the weather concerns, human technology was able to fix the problem with lighthouses, sonar, and radio equipment to steer clear of any obstacles. If you are at the beach or at the coastline, it's best to stay away from floodwaters. Also to stay in a solid sturdy area that can't be broken into with any leaks.

    Hello Addison,
    I found it interesting how many problems Canada faces when it comes to coastal erosions, compared to my country. My country doesn't have that many occurrences of coastal erosions.

Addison's Blog Issue #15: Fire Safety

 Canadian Geological Discoveries: Wild Fires December 7, 2022 This week for Addison's blog, we will discuss the details of forest fires. Forest Fires are weather disasters that happen in the dry plantation area of the environment. These are one of the most dangerous situations that can happen in any dry forest due to their material being extremely flammable. What causes them and how they affect the environment are great questions, which is why we are going to explain them here in this blog. So what causes a wildfire? Now sometimes it can either be started by lightning strikes in the skies, but this can only happen at certain points in time, depending on the weather. Research shows that about 10 to 20% of lightning strikes cause a fire to burst on the earth, after 100,000 hits from the storms.  However, most of the wildfires are caused by what I call, "Human Error". This is because when people are careless, they can do things that make their surroundings a bit worse. For e...

 Canadian Geological Discoveries: Tectonic Plate Boundaries August 30, 2022 Today on Addison's Blog we have received new information about the interesting groundbreaking facts about Canada's geological structure; tectonic plates. Now those of you who are curious about what those are, the answer can be explained through science. According to National Geographic, Tectonic Plates are a theory of how the earth's crusts and landforms were created during the beginning of time. However, in the ancient 1960s, these movements were furtherly developed when natural disasters such as volcanoes, earthquakes, and mountain building.  Now there are a total of 7 tectonic plates which surround the 7 continents of the world which are, North America, South America, Africa, Europe, Asia, Oceania (Into-Australia), and Antarctica. There are also some minor plates that are made when the bigger plates intercept. A prime example is the Philippines, between the Eurasian plate, the Pacific plate, and ...
