Global Largest Earthquakes in June 2022

According to the United States Geological Survey (USGS) earthquake report, we witnessed 1,217 earthquakes with a magnitude of 4.0 and above in June 2022.

Among them, 1,096 were of magnitude 4.0 to 4.9, 117 of magnitude 5.0 to 5.9, and 4 of magnitude 6.0 and above1.

In June we witnessed 31 earthquakes more than in May, 242 less than in April, and 45 more than in March.

The largest earthquake in June was of magnitude 6.5 on June 7th, 2022, at a great depth of 592 km, 112 km southwest of Tarauaca, Acre, Brazil. However, it did not cause any damage since it occurred at such a big depth that it was almost not felt on the surface2.

The second largest earthquake in June was of a magnitude of 6.4 and of depth 10 km, west of Macquarie Island, Tasmania offshore, Australia. Luckily it did not cause any damage since it was too distant from people and infrastructure.

The deadliest earthquake occurred on the 21st of June in Afghanistan, 46 km southwest of Khost. A magnitude 5.9 earthquake that occurred at the depth of 10 km killed more than 1,150 people, including 121 children, while 3,000 more got injured. More than 10,000 houses were destroyed and many landslides were caused.

The earthquake was a result of the stress built up from the collision of the Indian and Eurasian plates, which could be equivalent to 37 times the energy released by the atomic bomb dropped on Hiroshima, according to the US Federal Emergency Management Agency3.

Afghanistan is very prone to earthquakes because it is located on top of a number of fault lines where the Indian and Eurasian plates meet. Earthquakes there tend to cause big damage since most of the buildings are not earthquake-resistant and they tend to be built of timber and adobe - a type of mud brick - or out of weak concrete3.

The following graph shows that the earthquake occurred after a strong increase in the shear traction in the region.

In June, China was another country that suffered great losses due to earthquakes. On the 1st of June, a magnitude 5.8 earthquake struck Lushan County in Ya'an, Sichuan Province. At least four people were killed and 42 got injured. An estimated 10 million residents living around the earthquake epicenter received the early warning at least nine seconds before the mainshock4.

On the 9th of June, another magnitude 5.9 earthquake struck Sichuan, this time 254 km northwest of Tianpeng. It occurred at the depth of 14 km and left damage to nearly 500 houses and other infrastructure. Four people got injured and more than 25,000 got evacuated5.

Most of the earthquakes in Sichuan occur because of the collision between the Indian and Eurasian tectonic plates. As India drives northward into Asia, it forces the Tibetan Plateau out of its way, eastward into China2, causing the entire region to be frequently stricken by earthquakes.

The figure below shows one of the synchronized tectonic waves right before the magnitude 5.9 earthquake in Sichuan, which also triggered earthquakes in the Philippines, Indonesia, and Kashmir-Xinjiang Border Region.
