MEXICO CITY, MEXICO - El Popo has rumbled once again, triggered by yet another earthquake just one week after the last.

Mexico's largest volcano, El Popocatépetl, reawoke on Saturday and Sunday, with 78 low-intensity exhalations cued by a magnitude 1.8 earthquake. The ash and gas emitting from the mouth of the crater reportedly made slim-to-no visibility of El Popo, with a 12 kilometer (almost 7.5 mile) radius in place of no-entry.

The activity, according to news source Express, has some asking if the increased seismic activity over the past week and a half could be a prelude for “the big” eruption, one that it hasn’t had taken place in over 15 years.

The last time El Popo demonstrated its full power was in 2000, necessitating the evacuation of about 41,000 people.

The local population continues to be on alert since the volcano first rumbled to life earlier this year, when it emitted enough ash to necessitate shutting down local air traffic and halting some transportation in the Mexico City area.

Thus far, however, no such measures have been necessary. AndNowUKnow will continue to follow the story for any further developments.
