BRAZIL – A rather
shallow 5.8 magnitude earthquake struck the ocean floor just off the
coast of Brazil, south of the popular tourist destination of Natal. The eastern
coast of Brazil is relatively free from faults and is not located on the border
of any major tectonic plates. So this earthquake is quite unusual. If we look
at the seismic hazard map of Brazil (below), it’s clear to see that most
of Brazil’s seismic hazards lie in the western part of the country. See local
quake map of Brazil.
In 2010, Brazilian seismologist
João Carlos Dourado, from Universidade Estadual Paulista, explained in an
interview to G1 that Brazil is located at the center of the South American
tectonic plate and therefore away from the stresses on the plate edges, which cause
earthquakes of the magnitude that plague Chile and countries on the western
coast of South America. Today’s earthquake struck at a depth of 15.1 km (9.4
miles) under the Atlantic Ocean floor. The epicenter of the earthquake was 93
km (57 miles) E of Itamaraca, Brazil.
Unusual
Is this quake from a previously
unknown fault this close to the shoreline or might other factors be at work
here…like the area of growing weakness of the planet’s magnetic field in the
South Atlantic Anomaly? Natal is virtually near the epicenter of the SAA. The
South Atlantic Anomaly (SAA) is an area where the Earth’s inner Van Allen
radiation belt comes closest to the Earth’s surface dipping down to an altitude
of 200km (124mi). This leads to an increased flux of energetic particles in
this region and exposes orbiting satellites to higher than usual levels of
radiation. The effect is caused by the non-concentricity of the Earth and its
magnetic dipole, and the SAA is the near-Earth region where the Earth’s
magnetic field is weakest.
