CLIMATE CHANGE

    CUERNAVACA MEXICO   

Cuernavaca is the City I was born and raised.  Cuernavaca is known as the City of Eternal Spring because of its temperate climate and the profusion of flowering plants in its parks and gardens.

It is a beautiful place with a lot of lakes, rivers, great places to visit, it's one of the most attractive touristic places in Mexico, I remember growing up, going to hikes.  It has long been favored by Mexico’s ruling elites, who have maintained manor houses (Quintas) in exclusive Cuernavaca neighborhoods, spending weekends or vacations there to escape the poor weather and pollution of Mexico City. Or that's what we thought 10 years ago.

Cuernavaca has become now one of the cities with more pollution since hundreds of companies have arrive to this beautiful place.

Here are some graphics of how much the Pollution in Cuernavaca has changed:

ANATOMY OF MID-OCEAN RIDGES

 WHAT IS AN ANATOMY OF MID-OCEAN RIDGES? 

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.

This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. In Mexico, we can find ocean Ridges, in the photo below I'm going to identify some of the features in the Pacific Ocean zone and the Gulf of Mexico.

On the next picture, I will focus on the Pacific ocean, located on the east part of Mexico, over there we can find the Tehuantepec ridge, Tehuantepec is a linear undersea ridge, and it is the remnant of an old fracture zone.

PLATE TECTONICS IN THE NEWS

Mexico is in the worst possible place for earthquakes here's why it keeps getting hit.

NEWS:  https://www.businessinsider.com/why-mexico-earthquakes-science-2018-2

Mexico is one of the most seismically active countries in the world. Over the past century, the country has seen 19 earthquakes within 155 miles of the epicenter of last year's earthquake, according to the US Geological Survey

The country sits atop three of the Earth's largest tectonic plates — the North American plate, the Cocos Plate, and the Pacific Plate. Whenever these chunks of crust grind or butt up against one another, earthquakes happen. As a former lakebed, Mexico City is also home to soft soil that essentially acts as an amplifier for tremors, often making smaller earthquakes feel much larger.

Why does Mexico have more earthquakes?

Another fact is that "The Cocos Plate: is subducting under the North American Plate at a rate of 67 mm (0.220 ft) per year, while the Pacific and Rivera plates are moving northwest relative to the North American Plate. Southern Mexico also contains numerous faults, which causes that section of the country to have high tectonic activity.

EARTHQUAKE IN OAXACA

A magnitude  7.4  earthquake struck offshore Oaxaca, Mexico,  on  June 23, 2020,  at 11:30 a.m. ET. Seismic instruments indicate the earthquake originated at a depth of 16 miles (26 km).  

The Santa Maria Oaxaca earthquake is one of the 20 earthquakes happening this past 30 Days. This Earthquake happened yesterday. I'm from Cuernavaca Morelos, our state is very close to Oaxaca. My younger sister called me because she felt the earthquake, I know how bad this earthquake was because my family was there.

The June 23, 2020, M 7.4 earthquake near Oaxaca, Mexico occurred as the result of reverse faulting on or near the plate boundary between the Cocos and North American plates

• The powerful quake, centered near the Pacific Coast in Oaxaca, was felt hundreds of miles away.
• At least six people died, but reports indicated that damage was not extensive.
• The quake put people on the lookout for a possible tsunami.
• Oaxaca State has been devastated by earthquakes before.

 SAMALAYUCA DUNES 

This place is truly unique. The golden, soft sand dunes landscape, will make you feel like you’re standing somewhere in the Sahara Desert. Even tho, the Samalayuca Dunes are not close to where I live in Mexico, this place is one place that I will love visiting someday.

The Samalayuca Dune Fields, more traditionally known as Los Medanos (the dunes), or more recently referenced as Medanos de Samalayuca is a series of large but separated fields of sand dunes located in the northern part of the Mexican state of Chihuahua. The dune fields are scattered over a wide expanse of desert to the south, southwest, and southeast of Ciudad Juárez. The dune fields are located in a 2000 km² area known as the Samalayuca Desert. 

The dunes are composed of almost pure quartz (SiO₂). They are white or tan in appearance. They are fine and move with the wind. The wind has formed the dunes by carrying sand until it became deposited and concentrated in natural land depressions. The action of the wind continues to constantly reshape

Samalayuca is perfect for practicing one of the most exhilarating sports ever: sandboarding! It consists of sliding down the sand dunes on top of a board, similar to the ones used for snowboarding!!

A Fictional Narrative

Once upon a time, thousands of years ago, one civilization raised in Mexico known as the Geysersus, that name came from the Geysers a type of hot springs in the area. The Geysers were really passionate about politics, agriculture, and wars. One day during the Sun celebration the Geysers were at the Valley, close to the purchase water table, treating to collect water to be prepared for the biggest drought of the year, because of people necessity to survive they started wars for all the valley, killing each other in order to have the unsaturated zones giving them access to water, they fought for the Springs and one tragic day they decided to don't be part of the Geyserseus anymore, the people created another society with the name of Travetineus, this name came from the word "Travertine" is a deposit of calcite formed around the hot springs. The name was a threat for the Geysers, they felt that they wanted to have control over the valley so they decided to take their wives and children an establish their civilization somewhere else. They run, hid, and walked for months, and then they found a place that they would never be found, a place with accessibility to all the natural resources; they established their new civilization under the weather, in the caves.  During the time living there, they found material that they had never seen before like speleothems, stalactites, and geodes, the geodes became the barter
system and because that crystal was unique everybody accepted and gave them what they needed, and this is how the Geysersus had their happy ever after. 

FIND A LANDSLIDE

 Tijuana's Landslide  

Tijuana is a border city in Mexico, just south of California. Its bustling main street, Avenida Revolución, is lined with souvenir shops and lively bars. Landmarks include the neoclassical Jai Alai Frontón palace and Centro Cultural Tijuana, a modern cultural complex in the Zona Río district. Throughout town, stadiums stage Lucha libre (wrestling) matches, while the nearby city of Rosarito fronts sandy beaches

Two years ago on February 3, 2018, Tijuana suffered one of the biggest landslides in Mexico 89 homes were destroyed after landslide hits Tijuana. I haven't been in a landslide before, I was on my mission In Brazil when this happened, I remember crossing by a store and watched what was happening in my country. 

This is a Testimony of one of the affected citizens in Tijuana: "Our house was falling to pieces. Wood, stones, and cement were all over the place since Monday, and things started getting worse by Tuesday and Wednesday. The ground was literally sinking until we could no longer enter or exit our house. We had to jump over the cracks in order to get our stuff out of the house last night. "

How do Landslides occur?

A landslide occurs because the force of gravity becomes greater than either friction or the internal strength of the rock, soil, or sediment. The amount of friction between a deposit of rock or soil and the slope that it rests on plays a large role in when landslides happen.
