In Mexico, at least 12 people were killed and over 100 were injured, according to the country's National Civil Protection Coordination (CNPC).

The earthquake also triggered landslides and rockslides in both countries, with reports of several villages being buried under mud and debris. In Guatemala, at least 15 villages were affected by landslides, and over 1,000 people were evacuated from their homes. In Mexico, at least 10 villages were affected by landslides, and over 500 people were evacuated.

The earthquake also caused significant damage to infrastructure, including roads, bridges, and buildings. In Guatemala, the earthquake damaged several historic buildings in the city of Antigua, including the San Francisco Church and the University of San Carlos. In Mexico, the earthquake damaged several buildings in the states of Mexico and Puebla, including the historic Cathedral of the Assumption in the city of Puebla.

The earthquake was felt in several other countries in Central America and Mexico, including El Salvador, Honduras, Nicaragua, and Belize. The earthquake also triggered a tsunami warning in the Pacific Ocean, but it was later cancelled.

According to the USGS, the earthquake was one of the largest to strike the region in recent years, and was felt by millions of people. The earthquake was also one of the deadliest in recent years, with the death toll continuing to rise in the days and weeks following the earthquake.

In conclusion, the 2014 Mexico Guatemala earthquake was a powerful and devastating event that caused significant damage and loss of life in both countries. The earthquake was caused by the movement of the Cocos Plate beneath the North American Plate, and was characterized by the USGS as a "deep" earthquake. The earthquake triggered landslides and rockslides, and caused significant damage to infrastructure, including buildings, roads, and bridges. The earthquake was felt in several other countries in Central America and Mexico, and was one of the largest and deadliest in recent years.

What causes an earthquake

Earthquakes are primarily caused by the movement of tectonic plates, which are large sections of the Earth's crust that float on the semi-fluid mantle beneath them. The theory that explains this movement is known as plate tectonics. According to this theory, the Earth's lithosphere (which includes the crust and uppermost part of the mantle) is divided into several large and small plates that interact with each other.

There are three main types of plate boundaries where earthquakes commonly occur:

1. Convergent Boundaries: These boundaries occur when two plates collide or move towards each other. When one plate is forced beneath another in a process called subduction, it creates intense pressure and friction between the plates. This can lead to the accumulation of stress over time until it is released suddenly in the form of an earthquake. Convergent boundaries are responsible for some of the world's most powerful earthquakes, such as those along the Pacific Ring of Fire.

2. Divergent Boundaries: Divergent boundaries occur when two plates move away from each other, creating a gap or rift between them. As the plates separate, magma from the mantle rises to fill the gap, creating new crust. The movement and interaction of these plates can generate earthquakes, although they are generally less powerful than those at convergent boundaries.

3. Transform Boundaries: Transform boundaries occur when two plates slide past each other horizontally. The friction between these plates can cause them to become locked, building up stress until it is suddenly released in the form of an earthquake. Transform boundaries are known for producing shallow but powerful earthquakes, such as the San Andreas Fault in California.

Apart from plate tectonics, other factors can also contribute to the occurrence of earthquakes. These include:

- Volcanic Activity: Earthquakes can be triggered by volcanic activity when magma rises to the surface, causing the surrounding rocks to fracture and creating seismic activity. These earthquakes are often localized around the volcano and are known as volcanic or volcano-tectonic earthquakes.

- Human Activities: Certain human activities, such as mining, reservoir-induced seismicity (caused by the filling of large reservoirs), and hydraulic fracturing (fracking), can induce earthquakes. These induced earthquakes are generally of lower magnitude but can still cause damage in some cases.

Seismic Waves

When an earthquake occurs, it generates seismic waves that propagate through the Earth's interior and along its surface. There are three main types of seismic waves:

1. Primary Waves (P-waves): P-waves are compressional waves that travel through solids, liquids, and gases. They are the fastest seismic waves and are the first to be detected by seismographs. P-waves cause particles in the ground to move back and forth in the direction of wave propagation.

2. Secondary Waves (S-waves): S-waves are shear waves that travel only through solids. They are slower than P-waves and arrive at seismographs after P-waves. S-waves cause particles in the ground to move perpendicular to the direction of wave propagation.

3. Surface Waves: Surface waves travel along the Earth's surface and are responsible for most of the shaking felt during an earthquake. There are two types of surface waves: Love waves (horizontal motion) and Rayleigh waves (rolling motion).

Measuring Earthquakes

Earthquakes are measured using seismographs, which record the ground motion caused by seismic waves. The magnitude of an earthquake is a measure of the energy released during the event. The most commonly used scale for measuring earthquake magnitude is the Richter scale, developed by Charles F. Richter in 1935. The Richter scale is logarithmic, meaning that each whole number increase represents a tenfold increase in amplitude and approximately 31.6 times more energy release.

Another scale commonly used to measure earthquake intensity is the Modified Mercalli Intensity (MMI) scale. This scale assesses the effects of an earthquake on people, buildings, and the environment rather than measuring the energy released.
