The Mexican western states of Sonora, Baja California, Nayarit and Chiapas have been hit the last 24 hours by multiple earthquakes and aftershocks.
Everything seems to be moving and more tectonic movements may be expected.
4 different main areas can be defined.
a) The waters of the Gulf of California
With an epicenter in the coastal waters and a limited magnitude these earthquake can be categorized as safe.
b) The Sonora desert
The greater area of the massive M 7.2 earthquake from  April 4.  The epicenter of this earthquake was located more to the north in de border area between Mexico and the United States. Most of the aftershocks have an epicenter in unpopulated (beautiful!) desert areas.
c) The subduction zone of the Islas Marias islands
Active since a couple of weeks in various places and more or less in the greater Puerto Vallarta, Manzanilla zone.
Potentially dangerous if a shallow earthquake would strike nearer to the coastline.
d) Chiapas province
Regular (mostly deep) earthquakes with Magnitudes of +5. Harmless because of the depth of the hypocenter.
