Popocatépetl volcano, Central Mexico: news & activity updates

Wed, 23 Oct 2013, 06:00 CENAPRED reported that during 23-25 October seismicity at Popocatépetl indicated continuing emissions of water vapor, gas, and occasional small amounts of ash; cloud cover sometimes prevented observations of the crater. On 24 October an explosion at 2111 produced an ash plume that rose 1 km and drifted SW. Eight low-intensity explosions on 26 October increased gas and steam emissions and produced slight amounts of ash. Read all Tue, 22 Oct 2013, 10:05Activity remains very weak. Only 5-10 emissions of steam and gas were recorded per day recently. Tue, 22 Oct 2013, 06:38 No significant changes in (the currently weak) activity occurred. CENAPRED only recorded 5 weak emissions during 19-20 Oct. Fri, 18 Oct 2013, 05:59Following a small increase in the frequency of small explosive emissions during the previous days, activity has now decreased again to averages of less than 1 emission per hour. At night, crater glow remains visible. Tue, 15 Oct 2013, 14:32 No significant change in activity occurred, although a slightly increasing trend is visible in the past days. Emissions were at rates of 3 per hour on average yesterday. CENAPRED also recorded 10 explosions with ash plumes up to 1.5 km height. Some of them ejected incandescent material up to 300 m outside the crater on the northern slope. Alert status remains at Yellow Phase 2. Mon, 14 Oct 2013, 14:24The number of emissions (mainly steam puffs) has increased to about 3 per hour. A total of 8 small explosions, some of which ejected incandescent tephra outside the crater and produced small ash plumes were observed during the latest 24 hour report interval (CENAPRED). Read all Sun, 13 Oct 2013, 07:12 No changes have occurred. The volcano produces 1-2 generally weak emissions of steam and sometimes ash on average per hour. Thu, 10 Oct 2013, 14:24The number of emissions has increased to about 2 per hour, and several smaller explosions occurred during the past days, generating ash plumes reaching up to about 1 km above the crater. Sat, 5 Oct 2013, 13:53 No changes in the currently low activity have occurred. Moderate steaming, occasional weak ash venting / small explosions (at rates of approx once / 2 hours) and glow at the summit at night characterize the current phase. CENPARED's alert level remains "Yellow Phase 2". Thu, 3 Oct 2013, 16:12Activity has remained low with only weak emissions at averages of 1 every 1-2 hours. Occasionally, some ash explosions still occur, with plumes up to about 1 km height. Crater glow can still be seen at night and SO2 emission is strong, two indicators that magma continues to arrive at the summit (although at reduced rate).
