Two of the most significant earthquakes in these swarms were the November 5, 2011 Prague earthquake east of the Oklahoma City area and the September 3, 2016 earthquake near Pawnee, north of Prague. Oklahoma earthquake swarms (2009–present)

A magnitude 5.8 earthquake struck in Oklahoma on September 3, 2016 at 12:02:44 UTC (7:02 am local time). The USGS revised the magnitude from a 5.6 based on further in-depth analysis of seismic recordings. This is Oklahoma’s largest recorded earthquake to date.
Significant Earthquakes – 2019 5.09km S of Indios, Puerto Rico. 2019-12-29 01:06:00 UTC6.0 km. 6.3180km W of Port Hardy, Canada. 6.01km NNE of Lejanias, Colombia. 6.149km SW of Jarm, Afghanistan. 3.49km NNE of Snoqualmie, Washington. 6.87km S of Magsaysay, Philippines . 6.043km NW of Platanos, Greece. 5.34km SSE of Blagaj, Bosnia and Herzegovina.
A major earthquake registers between 7 and 7.9 on the Richter scale. There are about 20 a year worldwide and they cause very serious damage.
Is there any place in the world that doesn’t have earthquakes? Florida and North Dakota are the states with the fewest earthquakes.
The Hayward Fault is considered one of the most powerful fault lines in the world, running parallel to the potentially catastrophic San Andreas fault , and 150 years almost to the day, researchers warn it is overdue a quake.

The magnitude, location, and depth of an earthquake , and overlying soil conditions determine how widely and strongly any particular event can be felt. Typically, people report feeling earthquakes larger than about magnitude 3.0.
The largest earthquake known to be induced by hydraulic fracturing in Oklahoma was a M3. 6 earthquakes in 2019. The largest known fracking induced earthquake in the United States was a M4. The majority of earthquakes in Oklahoma are caused by the industrial practice known as “wastewater disposal”.
During 2020 , there were 8 quakes of magnitude 7.0 or above, 115 quakes between 6.0 and 7.0, 1689 quakes between 5.0 and 6.0, 12717 quakes between 4.0 and 5.0, 38940 quakes between 3.0 and 4.0, and 85166 quakes between 2.0 and 3.0. There were also 207007 quakes below magnitude 2.0 which people don’t normally feel.
For which country do we locate the most earthquakes? Japan . The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.
The National Earthquake Information Center (NEIC) records an average of 20,000 earthquakes every year (about 50 a day) around the world. There are, however, millions of earthquakes estimated to occur every year that are too weak to be recorded.
Earthquakes as Existential Risks. Earthquakes are not typically considered existential or even global catastrophic risks, and for good reason: they’re localized events. While they may be devastating to the local community, rarely do they impact the whole world .
No, earthquakes of magnitude 10 or larger cannot happen. No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.
Dogs have a wider hearing range and better scent detection than humans. Some scientists suggest that dogs can hear seismic activities that precede earthquakes (such as the scraping, grinding, and breaking of rocks underground). If their hearing is impaired, they are less likely to detect quakes, Coren writes.
