An earthquake with a reviewed magnitude of 6.2 shook west of city of Adak in Alaska on Thursday, according to the US Geological Survey.
The last week has seen an uptick in bigger earthquakes worldwide, also in the usual North American region. This week 14 out of 100 earthquakes equal or greater than 4.5 fell in the map region and 1564 out of 2087 of earthquakes of all sizes. This amounts to 74.9%.The numbers for this week: 2 out of 79 earthquakes worldwide greater or equal to 4.5 and 1518 out of 2180 worldwide of all sizes in the map area. That amounts to 69.6%.
Given the large number of earthquakes, researchers have already mobilized and there are various hypotheses about what is happening in Michoacán.
A group of researchers from the Universidad Michoacana de San Nicolás de Hidalgo (UMSNH) ruled out risks due to the constant telluric movements.
They assured that it is very unlikely that these movements will predict an explosion of the volcano or the birth of another one, and said that "the most likely is that the current seismic swarm is related to the movement and re-arrangement of the regional faults... there is no reason for alarm," said Martha Gabriela Gómez, a researcher at Inicit.
They also said that it is not known how much longer the seismic swarms in the area will last - it could be hours, days, months or even years.
Meanwhile, Dr. Patricia Alarcón, specialist and coordinator of the Simian Test Laboratory at the University of Michoacan's (UMSNH) Civil Engineering School, dismissed the state's Civil Protection hypothesis that the small earthquakes are resetting the subsoil due to water extraction in agricultural areas.
The expert explained that the zone where the magmatic movement is registered is surrounded by monogenetic volcanoes, the energy would not have a way to reach the surface, which would be causing the movements.
She pointed out that the magma channels found at a depth of 40 kilometers are still active.
While Guillermo Martínez Ruiz, doctor from the Polytechnic University of Catalonia in Barcelona, Spain, has pointed out that what is being experienced at this time in Michoacán had not occurred, he said that it has been a greater seismic swarm than previous ones.
They agree that more research needs to be done
Although the hypotheses of what is generating the constant seismic movement are diverse, the researchers agree that to affirm or to discard any outbreak of a new volcano or the reason of the seismic activity, more studies must be made.
The topic is already on the agenda of the specialists, and even of the National Seismologist who yesterday issued a special communiqué to report the tremors in the region.
The telluric movements have also attracted the attention of the Smartnav platform, which is in charge of integrating electronic and aeronautical systems for monitoring and surveillance.
Smartnav shared on its social networks that it already monitors the Purepecha plateau area, following the constant earthquakes in the vicinity of Paricutin Volcano, where it is performing an aerial thermal analysis of the volcano.
