Popocatépetl volcano (Mexico): rapid decrease in tremorThe high-frequency tremor signal has decreased significantly over the past 48 hours, the CENAPRED reported.
Seismic records registered 11 minutes of amplitude tremor over the past 24 hours associated with 219 emissions of light amounts of ash and occasional incandescent fragments.
Vulcanian activity continues from the summit vent at weakened levels but still remains above long-term average values. Ash plumes continue to reach nearly the same altitudes of about 19,000 ft-20,000 ft (5,800 m-6,100 m) drifting south.
The crater area of the volcano remains closed for climbing as the risk of being caught in sudden explosions is very high. The alert status remains at Yellow Phase 3.
People are advised to avoid the crater area within a 12 km radius. Additionally, the warning bulletin states that lahars (mud flows) could also occur if heavy rainfalls remobilize fresh ashfall deposits.
