TThe earthquake that rocked the port of Manzanillo caused the sea to rise today, September 19, with reports indicating a magnitude of 7.7.
The earthquake occurred on Monday afternoon, and it activated a seismic alert for the possibility of a tsunami on the Mexican Pacific coast, however, authorities acknowledged that the tsunami did not occur.
At about 3:54 p.m., the National Autonomous University of Mexico (UNAM) reported a “sea level rise” recorded in Manzanillo, Colima.
According to the UNAM report, the maximum recorded amplitude was more than 1 meter: 124 cm
“Monitoring stations in the area near the earthquake in the Mexican Pacific recorded a sea level rise. The Manzanillo station detected a maximum amplitude of 124 cm,” UNAM reported via its Twitter profile.
Tsunami ruled out
Despite the bulging differences, tsunami formation has so far been ruled out. The Civil Protection of Colima stated that there is no possibility of this event occurring, “although significant differences are expected, we reiterate the avoidance of approaching the beaches,” she wrote on her social networks.
According to information from the Mexican government, earthquake is the main cause of tsunamis. For an earthquake to cause a tsunami, the sea floor must be suddenly moved vertically to push the ocean out of its natural equilibrium.
When this massive mass of water tries to restore its balance, waves are generated. The magnitude of the tsunami is determined by the magnitude of the vertical deformation of the sea floor. Not all earthquakes generate tsunamis, but only earthquakes of large size, which occur under the sea floor and are capable of distorting it.
