In the past two weeks the activity of Popocatépetl volcano has increased. Today an increase in the general levels of activity was noticed, in particular some explosions, volcanotectonic seisms, tremor episodes and exhalation trains, so based on the recomendatio of the Scientific Assesing Comitee, the Interior Ministry decided to increase the Volcanic Alert Level to Yellow, Phase 3.

May 12 10:00 h (May 12, 15:00 GMT)

The increase in the general activity of Popocatepetl volcano during the last weeks and especially the acceleration of the seismic activity registered yesterday, today at 01:40 am, the Interior Ministry raised the Volcanic Alert Level to Yellow Phase 3. During the period in which the volcanic traffic light remains in this level, two bulletins will be issued daily: the first at 10:00 am, with a summary of the activity of the last 24 h and the second at 07:00 pm, featuring updating the data reported in the first. If necessary, the updates will be reported more frequently.

During the last 24 h, the monitoring system of Popocatepetl volcano registered a long episode of harmonic tremor of high amplitude, beginning yesterday at 16:00 h (local time) until 05:45 h (local time) of this early morning (see image 1). This activity was accompanied by the emission of a continuous steam and gas plume, containing small to moderate amounts of ash, which was released in denser pulses (see image 2). The emission of incandescent fragments was also observed sporadically, which mainly fell in to the crater interior. However, at 01:10 h, some part of these fragments fell on the highest part of the volcano north-northeast flanks, at maximum distance of 300 m (see imagen 3), (seeimagen 4). The tremor was registered in several stages of 1 to 2 hours of duration, continuously or in segments. Each stage began with an explosion of moderate intensity. The most important occurred at 17:00 h (local time) and was perceived by much of the villages close to the east and southeast flanks of the volcano.

From 05:45 h to 07:26 h the harmonic tremor decreased in amplitude and was registered in segments, which gradually spaced themself. At 07:27 h (see image 5) and at 08:10 h, two other exhalations with explosive component were recorded and were followed by new segments of harmonic tremor of high amplitude, between 08:39 h and 08:58 h.

Additionally, during the last 24 h the monitoring system registered 60 exhalations of low to moderate intensity, accompanied by the emission of a steam and gas plume, and possibly by small to moderate amounts of ash; although it was not possible to observe this clearly...

Even if seismicity is frequent in this area, one is impressed by the seismic swarm that is taking place off the Reykjanes Peninsula. These tectonic events show the forces that are exerted in Iceland, the emergence of the Mid-Atlantic ridge and the witness of the accretion between the North American and Eurasian plates.


the melt season began, the main events ahead

May 12 19:00 h (May 13, 00:00 GMT)
Since the last bulletin at 10:00 h, the monitoring system of Popocatépetl volcano registered 3 h of segments of harmonic tremor of medium and high amplitude, between 10:00 h and 11:12 h, and since 17:30 h to the moment of this report. Additionally, the system registered 20 exhalations of low to moderate intensity. The most important occurred at 14:16 h, which had explosive component.
Until an hour ago there was not visibility to the volcano, due to the cloudy conditions in the area. Since 18:00 h it was possible to observe the crater and the continuous emission of a steam and gas plume, and occasionally denser pulses containing small to moderate amounts of ash (see image 8), heading to northeast.
The harmonic tremor that began at 17:30 h continues at the moment to finish this report and has a tendency to increase.

Global carbon dioxide levels near worrisome milestone
Concentrations of greenhouse gas will soon surpass 400 parts per million at sentinel spot.

Richard Monastersky 30 April 2013

Near the moonscape summit of the Mauna Loa volcano in Hawaii, an infrared analyser will soon make history. Sometime in the next month, it is expected to record a daily concentration of carbon dioxide in the atmosphere of more than 400 parts per million (p.p.m.), a value not reached at this key surveillance point for a few million years...

May 14 10:00 h (May 14, 15:00 GMT)
During the last 24 hours volcanic monitoring system registered about 3 hours of middle-amplitude harmonic tremor and sometimes showed saturation in the registry. The tremor was made in segments pulses with durations up to 17 minutes maximum. Additionally there have been 27 exhalations, however relevant climatic conditions of yesterday did not allow clearly see the volcano, thus, can not confirm the emission of ash during the afternoon.

At 15:52 h and 21:49 h of the day yesterday, two volcanotectonic events was registered of Mc = 1.6 and 1.4 degrees. Today at 08:01 h was an event of Mc = 1.9 degrees. At 09:56 h there was an explosive event that generated an emission of steam and gas with moderate amounts of ash that reached a height of 3 km above the crater and threw fragments fell over a distance of 600 m on the side of the volcano, according to the wind direction, the emision had a NE direction. Prior to the explosion plume emission was observed with a vertical direction and narrow shape. (see Figure 1) . (see Figure 2) . (see picture 3) . (see picture 4) . (see figure 5) . (see figure 6) . (see Figure 7) . From the town of Tianguismanalco shows the emission of ash that can be clearly differentiated from the area of cloudiness in the volcano. (see Figure 8) .

Volcano: Pavlof (CAVW #1102-03-)

Current Volcano Alert Level: WATCH
Previous Volcano Alert Level: NORMAL

Current Aviation Color Code: ORANGE
Previous Aviation Color Code: GREEN

Issued: Monday, May 13, 2013, 11:38 AM AKDT (20130513/1938Z)
Source: Alaska Volcano Observatory
Notice Number: 2013/A9
Location: N 55 deg 25 min W 161 deg 53 min
Elevation: 8261 ft (2518 m)
Area: Alaska Peninsula Alaska

Volcanic Activity Summary: Seismic activity at Pavlof Volcano increased this morning commensurate with the presence of an intense thermal anomaly at the summit observed in latest satellite imagery. Similar patterns of seismicity and elevated surface temperatures have previously signaled the onset of eruptive activity at Pavlof. Although not yet visually confirmed, a low-level eruption of lava has likely begun from a summit vent. No ash clouds have been detected...

Pavlof
Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 2007
...Pavlof has been frequently active in historical time, typically producing strombolian to vulcanian explosive eruptions from the summit vents and occasional lava flows. The active vents lie near the summit on the north and east sides. The largest historical eruption of Pavlof took place in 1911, at the end of a 5-year-long eruptive episode. During this eruption a fissure opened on the northern flank of the volcano, ejecting large blocks and issuing lava flows.
