Earthquakes and Geology in Costa Rica：

"the Nicoya gap has the potential to generate an earthquake with moment magnitude above 7.5".
The “Nicoya seismic gap” is bounded by the rupture areas of two large earthquakes that occurred at both sides of this peninsula; MW 7.0 in 1990 to the southeast and the 1992 MW 7.6 off Nicaragua to the northwest. A strong coupling of the two plates is manifested in this seismic gap by low background seismicity, the sharp edge to the aftershock zone of the 1990 and 1992 earthquakes , and the northeastward movement of the Nicoya peninsula recorded with GPS observations. Protti et al. estimated that a MW=7.5 earthquake is likely to occur in the Nicoya seismic gap.

radio transmissions can give San Jose about 30 seconds of warning before the earthquake waves demolish the city.
On the Nicoya Peninsula, however, there will be no prior warning.
