A magnitude-5.9 earthquake struck 152 kilometres southwest of Tonalá, Chiapas, at 20:21 local time on Sunday, 11 August, according to Mexico’s National Seismological Service. The state civil-protection agency said no casualties or material damage had been reported and the tremor was not felt in Mexico City. Authorities activated monitoring protocols, warning coastal communities to stay alert for strong currents even though significant sea-level changes were unlikely. Less than a week later, a separate magnitude-5.7 quake hit near Kingaroy in south-east Queensland at about midnight local time on 16 August, shaking Brisbane and surrounding areas. Australia’s Geoscience agency and emergency services said there was no tsunami risk and initial inspections had found no serious damage or injuries. Both events underline the need for continued preparedness in regions not usually associated with major seismic activity.
