Earthquakes today, June 3
The United States Geological Service (USGSfor its acronym in English) is one of the scientific reference agencies when it comes to registration and monitoring of Seísos throughout the globe. As the organization states, its functions go through “a wide range of data” to support decision making in the field of environment, resources and public safety.
Next, the newspaper facilitates a map configured from the latest USGS data. You can consult both the location like the magnitude exact of the earthquakes that have taken place in the last 24 hours around the world.
How is the magnitude of an earthquake measure?
If we talk about the magnitude of an earthquake, it is inevitable to mention the Richter Scale. Developed in 1935 by the American physicist Charles F. Richter, from whom he adopts the name, this logarithmic scale serves to measure the amount of energy released in the focus of an earthquake from the amplitude of the Seismic waves registered by the sismógrafos.
While it is a pioneer scale, it is not the only one. In addition to Richter, there are other scales, some of them with greater precision; This is the case of Magnitude scale (MW). There are also other alternatives to measure different parameters, such as the scale of Mercalli Edita (MMI) or of Wave body magnitude (MB)among others.
Stronger and deadly earthquakes in history
According to USGS data, the earthquake stronger Never registered – the first records date back to 1769with the first documented earthquake, in California – he shook the south of Chile he May 22, 1960with a magnitude of 9,5 Mw. This earthquake caused a enorme tsunami which affected several countries throughout the Pacific Ocean, leaving thousands of dead and huge material damage.
Also, the aforementioned agency collects that the earthquake Most deadly of which you have registration occurred in the year 1556in center of China. It affected an area where most of the inhabitants lived in caves excavated in soft rock, which collapsed during the earthquake, causing the death of some 830.000 personas. Years later, in 1976another devastating earthquake shook the city of Tangshanalso in China, causing the death of more than 250.000 personas.
