Strong earthquake shakes Panama and halts the capital’s metro
A strong earthquake shook Panama on Saturday morning, 31 October, sending tremors through the capital and forcing the Panama Metro to stop its trains and evacuate its passengers.
The quake struck at 10:50am local time, with its epicentre near Tonosí in Los Santos province, on the country’s Pacific coast. The US Geological Survey measured it at magnitude 5.2, while Panama’s own Instituto de Geociencias put it at 5.9. The European-Mediterranean centre gave a figure in between, at 5.7.
In Panama City, the shaking was strong enough for the Metro to suspend Lines 1 and 2 as a safety measure. Passengers were led out of trains and stations, and students were moved out of classrooms at the University of Panama. Service was back to normal about an hour later.
The civil protection agency, Sinaproc, said no injuries or damage had been reported from the new quake. Néstor Luque, the director of the geosciences institute, said the quake could not cause a tsunami, so no warning was issued.
Why it matters
This was not a one-off tremor. The region around Los Santos has been shaking for weeks, ever since a powerful earthquake struck on 9 October. Panama’s geosciences institute has recorded more than 100 aftershocks since then, and this latest quake falls inside that same aftershock zone.
For people in the capital, the Metro shutdown was the most visible effect. The network carries huge numbers of commuters every day, so stopping both lines, even briefly, shows how seriously the safety routines are now taken after the October quake.
The disagreement over the size of the quake matters too. Early readings from different monitoring networks often differ, and Panama’s institute revised its first estimate down from 6.1 to 5.9 as more data came in. The US figure of 5.2 may also be revised. That is normal in the first hours after a quake, and it is why officials wait before giving a final number.
What happens next
More aftershocks remain likely in the Los Santos area, and the geosciences institute is continuing to monitor the fault zone around the clock. Sinaproc is keeping its emergency operations centre active and asking people to stay alert.
Residents have been advised to check their homes for cracks and to keep emergency supplies ready, while the Metro will keep running normally unless another strong tremor forces a further stop.
