La Palma (Canary Islands (Spain)): (15 Sep) The seismic crisis continues with no signs of slowing. More than 250 quakes large enough to be located were detected during the past 24 hours. Minutes ago, a magnitude 3.2 event at only 4 km depth occurred and was felt.
This quake can be seen on the seismic trace as the large green signal.

Karymsky (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 and is moving at 15 kts in S direction.
The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:15/1120Z to 12000 ft (3700 m)

The local observatory cited in their latest bulletin: Observations of ash has been intermittent, and the amount of ash carried in the plume is small. When we have observed ash in the plume, these periods were not accompanied by impulsive or explosive seismic or acoustic signals, hence showing no evidence of eruption.
In the case of prevailing northern winds, fresh ash deposits may occur along the Bay of Plenty coastline.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 24000 ft (7300 m) altitude or flight level 240 .
