Moderate explosions occurred at Popocatépetl on 18 December. After a period of high-frequency tremor, an explosion occurred at 0148 that produced an ash cloud that reached 2 km above the crater. Later, at 0209 and 0214 two explosions sent ash to ~0.5 km above the crater. that drifted to the NE.
During December there were several emissions of steam, gas, and minor amounts of ash at Popocatépetl. According to CENAPRED, new episodes of low-frequency tremor, beginning on 19 November, signaled the growth of a new lava dome within Popocatépetl's crater. Aerial photographs obtained by the Mexican Ministry of Communications and Transportation on 2 December confirmed the presence of a fresh lava dome measuring about 180 m in diameter at its base, and about 52 m high.
