In other years the total was well below the annual long-term average of 16 major earthquakes. 1989 only had 6 major earthquakes and 1988 only had 7. The year with the largest total was 2010, with 23 major earthquakes (greater than or equal to magnitude 7.0). In the past 40-50 years, our records show that we have exceeded the long-term average number of major earthquakes about a dozen times. That includes 15 earthquakes in the magnitude 7 range and one earthquake magnitude 8.0 or greater. As a result of the improvements in communications and the increased interest in natural disasters, the public now learns about earthquakes more quickly than ever before.Īccording to long-term records (since about 1900), we expect about 16 major earthquakes in any given year. The National Earthquake Information Center now locates about 20,000 earthquakes around the globe each year, or approximately 55 per day. Earthquakes stronger than about magnitude 5.0 generate ground motions that are strong enough to be damaging in the epicentral area. The ComCat earthquake catalog contains an increasing number of earthquakes in recent years-not because there are more earthquakes, but because there are more seismic instruments and they are able to record more earthquakes. earthquake, although uncommon, can be felt as far as 500 km (300 mi) from its epicenter, and can cause damage as far away as 40 km (25 mi) from its epicenter. An earthquake (also known as a tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Neither an increase nor decrease worldwide is a positive indication that a large earthquake is imminent. These scenarios represent reasonable estimates of the earthquake hazards in Washington State, and are to be used for planning.A temporary increase or decrease in seismicity is part of the normal fluctuation of earthquake rates.

The immediate interpretations that comes from this visualization are that underground injection wells do cause seismic activity.
