Tsunami threat after powerful 7.4 magnitude earthquake hits off Mexican coast
A tsunami warning has been issued after a magnitude 7.3 earthquake was recorded near the coast of Chiapas, Mexico, according to the United States Geological Survey (USGS).
The earthquake hit Puerto Madero, a major Pacific port and fishing town which is just 13km from the Guatemalan border.
The USGS said that the natural disaster was at a depth of 10 km (6.21 miles), as per Sky News.
While the quake was first recorded as having a magnitude of 7.4, it would later be revised down to 7.3.
Tremors like this can cause destructive secondary hazards, such as landslides and tsunamis, while shallower earthquakes usually cause more intense and concentrated damage and shaking.
Tsunami threats exist for parts of the Pacific which are nearer to the earthquake, according to USGS.
They add that "hazardous tsunami waves" are a possibility for coasts located within 300km of the epicentre of the earthquake which affected the Mexican town.
Region affected by aftershocks
It's been reported that aftershocks have hit the region after the initial earthquake struck the coast.
According to Mexico's national seismological service, smaller quakes have hit the region, with preliminary magnitudes of 5.2, 4.5 and 6.1 being recorded.
It's also been revealed that the earthquake shook buildings and resulted in residents rushing from their homes into the streets of Guatemala City, the country's capital.
Local media revealed videos of staff evacuating a government building, as per security protocols in preparation for the natural disaster.
This tremor was also felt as far as El Salvador, according to witnesses.
It's believed that tsunami waves reaching between 0.3m and 1m above tide level are possible for areas of Guatemala and Mexico, says the US Tsunami Warning System.
Waves are set to be less than 0.3m above tide level along the coasts of other nearby countries, such as Colombia, Costa Rica, and Ecuador, in addition to El Salvador, Honduras, Nicaragua, Panama, and Peru.
Governor of Oaxaca makes statement
Salomon Jara, the governor of the southern Mexican state of Oaxaca, took to social media, saying that no serious damage was immediately reported.
He said that the earthquake was also felt with "moderate intensity" in the state's capital.
While the numbers he reported were different to that of other news outlets, he has sent a message out to citizens in the area.
He wrote, translated from Spanish: "A preliminary magnitude 6.8 earthquake has been recorded with its epicenter in Chiapas; it was felt in Oaxaca.
"The seismic event was felt with moderate intensity. Immediately, Civil Protection agencies activated review and monitoring protocols in the various regions to verify possible impacts and safeguard the population.
"To date, no significant damage has been reported. Citizens are urged to remain calm, follow the authorities' recommendations, and stay informed solely through official channels."
