Ocean Hazards: Danger Equations
A long time ago, we watched this somewhat cheesy video about the "Danger Equations" of Ocean Hazards. A little too much math for some of the students...
Anyway, here are my official notes on this corny yet informative video (that we watched a LONG TIME AGO)
TSUNAMIS:
A Tsunami is an incredibly large and tall wave caused by earthquake and long landslides. There are many danger factors of tsunami such as the Burma plate. Burma plate is the India plate that caused the undersea-earthquake. Another factor is ocean wave physics. Ocean wave physics displaces water to do moving plates. The seafloor topography determines the tsunami's power. Tsunamis can rise up to 25 feet or more. The tsunami can cause a lot of damage as in the video, where it came to shore. When it came to shore it washed away vehicles, people, and palm trees. The tsunami also caused people to lose their lives. A Tsunami is a danger zone.
RIPTIDES:
Rip currents are a strong, narrow current flowing out from the beach, through the surf zone. This causes a hazard to people swimming there. People who are trying to get of the rip current keeps getting pulled back, so the best way to get out of rip current is to swim sideways out. Surf zone physic is where the water transforms in to hill with gravity trying to pull it back but it may be too strong. Underwater topography helps form rip waters. Inexperience is another factor that leads to danger when you don't know what to do in a rip current. Rip currents are a danger zone.

FINALLY... JELLYFISH!!! DISCLAIMER: ABOVE PICTURE MAY NOT BE AN ACCURATE REPRESENTATION, AS REAL JELLYFISH DO NOT HAVE CROWNS OR CAPES.
Jellyfish such as the Box jelly fish can be very dangerous, because of it's poison. The poison causes your blood pressure to rise and it gets to your head. This poison can even kill you. Low shorelines launch tsunami with steep waves which stops the waves and brings more jellyfish close to the shore. Another factor is that we have a shared habitat, where humans swim in Great Barrier Reef. Marine predators like the box jelly fish is one of the most deadliest predators. There is much more room for jellyfish in the already vast, open sea, because of the diminishing amount of other species of fish. Lastly due to unnatural weather patterns, it causes there to be more jellyfish.
