Floods

A flood is caused by excess water surpassing the limits of its confines. A flood can happen during a myriad of events, including heavy rainfall and overflowing river banks. Floods present a significant danger with enough force to sweet away massive objects such as cars and trees.

Effects of Floods:

• Saint Francis Dam - March 12, 1928:

" In 1928, the Saint Francis Dam in Los Angeles was filled with 12.5 billion gallons of water - enough water for one year for a population of 1.2 million people. However, on March 12, 1928, the dam broke, unleashing a 78 foot wall of water. It obliterated houses, ranches, automobiles, animals, and people. In roughly one hour, more than 500 people were killed and Santa Paula was overrun by water."

• Grand Forks Flood - April 18, 1997

" On Friday, April 18, 1997, the Red River flooded over the dikes into Grand Forks, North Dakota. At the end of Saturday, the19th, the flood waters had spread over a large area of Grand Forks and East Grand Forks. Roughly 60,000 people were forced from their homes and downtown Grand Forks was left in flames. The damage was so extensive that it was weeks before people could return and rebuild their homes - and their lives."

Hurricanes

Hurricanes are caused by complexes of thunderstorms that evolve into hurricane strength with the aid of the ocean and atmosphere. The water must be warm enough to provide energy for the hurricane. The warm water provides head moisture which, in turn, provides energy. This is why hurricanes quickly weaken when they travel over land or colder ocean waters, since they lack the warmth and the moisture.

The high humidity in the middle and lower troposphere assist in hurricane development, reducing the amount of evaporation in clouds and maximizing the latent heat released due to increased precipitation. The concentration of latent heat is essential to the system. Another important aspect of a tropical storm is the vertical wind shear, the amount of change in the wind.s direction or speed as the altitude increases.

When the wind shear is weak, the storms that are part of the cyclone grow vertically and the latent heat from condensation is released into the air above the storm, aiding in its development. The stronger the wind shear is, the more slanted the storm becomes and more latent heat is released and dispersed over a larger area.

This new article will feature a friendly animal, those who have seen them have most likely fell in love with the cute faces and playful personalities naturally displayed by the otter.

Many are those who are unaware that otters are naturally present inside our country’s borders; fewer are those who haven’t seen the couple that are almost Oceanario’s mascots, and even less fail to recall their spotlight on the news when the couple had a baby who unfortunately died.

The otter is common in Europe, Asia, seen in Northern America’s southern reaches and prevalent along all of southern America, such as Brazil and Argentina.

You might be wondering why is this animal near extinction if it is so commonly found on many continents.

Well, every animal species varies from habitat to habitat, and such a theory is relevant to this case. As Darwin once proved, a bird from one tropical island, even from the same species, can be different than the same species of bird but from an island, even if relatively close.



The same applies with our otter.
It can be a regular otter but this is different from other otters around the world, and nonetheless, we should always try to preserve what is ours.

There is one simple reason for this cute animal’s endangerment, which is the destruction of its specific habitats.
Like beavers, these animals need to live on particularly watery terrain, next to rivers or lakes being the most common habitat.
Damns, the use of pesticides on crops, climate changes, all of these contribute to the destruction and/or alteration of this creature’s habitat.
In Darwin’s example, one bird in one island had a beak better suited to eat the fruits of the island it was from, while the same species from a neighbour island had a less curvy and pointier beak, so it could eat the fruits with a harder shell and even hunt small rodents with more ease.

What are Eatrhquakes?

Earthquakes are natural disasters caused by a movement deep underground in the Earth’s tectonic plates. This natural disaster can destroy even the best built structures with his powerful.
Earthquakes can also cause others natural disasters, like, tsunamis or volcanic eruptions. It is unpredictable, occurring with no method of prediction, and are capable of killing many people.

One of the most Earthquakes was on 1 November 1755, in Lisbon, Portugal. This city was in ruins and in flames.

The Lisbon earthquake struck in mid-morning during a high religious holiday, All Souls Day. Shortly afterward, three large tsunamis swept over the city's harbor and killed many thousands of refugees. A week later, after untamable fires and unremitting aftershocks, essentially the whole city of Lisbon was in ashes, its people scattered, and perhaps half of its population dead.
