Mexico's Popocatépetl volcano erupted on Thursday with a dramatic show of lava and a cloud of ash and rocks that reached 3,000m (9,800ft) into the sky. No-one was hurt. Popocatépetl is an active stratovolcano, 70km (43 miles) south-east of the capital, Mexico City.
Mexico lies within two seismically active earthquake zones. Southern Mexico also contains numerous faults, which causes that section of the country to have high tectonic activity.
The epicenter of the earthquake — which struck Tuesday at 2:14 p.m. E.T. — was located in the town of Raboso, 76 miles southeast of Mexico City, which suffered significant damage.

Mexico's location makes the country prone to strong earthquakes because it is in a so-called subduction zone. Subduction zones are the parts of the earth where one slab of the crust is slowly sliding under another.

That means the people of Mexico City can feel nearly every major quake in the region, even if the epicenter is hundreds of miles away. This effect was notable during a magnitude 8.1 earthquake in 1985, which caused intense damage throughout Mexico City despite the fact that its epicenter was more than 200 miles away.
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.
Stay away from outer walls, windows, fireplaces, and hanging objects. If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows. If you are outside, go to an open area away from trees, telephone poles, and buildings, and stay there.
Where do earthquakes occur?
- The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet's largest earthquakes occur.
- The Alpide earthquake belt extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic.

FICTION: “Mega Quakes” can really happen.The largest earthquake ever recorded by seismic instruments anywhere on the earth was a magnitude 9.5 earthquake in Chile on May 22, 1960. That earthquake occurred on a fault that is almost 1,000 miles long and 150 miles wide, dipping into the earth at a shallow angle.
The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
The purpose of the ShakeAlert system is to identify and characterize an earthquake a few seconds after it begins, calculate the likely intensity of ground shaking that will result, and make alerts available for delivery (by over 60 ShakeAlert partners) to people and infrastructure in harm's way.
The earthquake hit at 4:53 pm some 15 miles (25 km) southwest of the Haitian capital of Port-au-Prince. The initial shock registered a magnitude of 7.0 and was soon followed by two aftershocks of magnitudes 5.9 and 5.5.
Faults in BajaThe main fault separating these plates — the San Andreas Fault — stretches through southern California, where it becomes the Imperial Fault south of the Salton Sea. In northern Mexico it continues as the Cerro Prieto Fault before it dives into the Gulf of California.
A powerful earthquake of magnitude 7.4 struck the coast of southern Mexico on Tuesday, killing at least one person, buckling paved roads, and setting off a tsunami in nearby Pacific coastal areas. People get to the streets in Mexico City following a quake on June 23, 2020 amid the COVID-19 novel coronavirus pandemic.
Earthquakes are also classified in categories ranging from minor to great, depending on their magnitude.
| Magnitude | Earthquake Effects | Estimated Number Each Year |
|---|
| 7.0 to 7.9 | Major earthquake. Serious damage. | 20 |
| 8.0 or greater | Great earthquake. Can totally destroy communities near the epicenter. | One every 5 to 10 years |
An earthquake of magnitude of 7.4 jolted China's Qinghai province today. Beijing, China: The Yunnan quake, which had a magnitude of 6.1, struck first at 9:48 pm Friday (1348 GMT) near the city of Dali, a popular tourist destination, the US Geological Survey said.
listen)), is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico.
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. The word tremor is also used for non-earthquake seismic rumbling.
A strong earthquake has struck central Mexico, killing more than 200 people and toppling dozens of buildings in the capital, Mexico City. At least 30 people, mostly children, died after a school collapsed in the capital, local media report. The 7.1 magnitude quake also caused major damage in neighbouring states.
