It seems like there have been a lot of earthquakes occuring in recent weeks, and scientists are noticing, says NBC. In April alone, a magnitude-8.2 tremor struck offshore of Iquique, Chile on Apr. 1; a magnitude-7.6 quake struck Solomon Islands on Apr. 12; and a 7.5-magnitude earthquake struck 164 miles southwest of Mexico City just last week.

According to NBC, scientists are analyzing seismic waves to see if the Apr. 1 earthquake may have triggered the numerous quakes that have followed, including the most recent one near Mexico City.

While there were some power outages as a result of the Mexico City quake, there were no reports of injuries or major damage. This was welcome news to a city that still remembers the 8.1-magnitude earthquake that hit it in 1985, killing over 9,000.

The 1985 Mexico City Earthquake is one of 20 quakes ranked by Swiss Re as the costliest earthquakes by insured losses (adjusted for inflation). Keep reading to learn about the 20 earthquakes on the list.
