Iceland Earthquake Swarm
An earthquake swarm continues off the north coast of Iceland. Over the past 48 hours there have been 209 earthquakes recorded. The closest volcano to the swarm is Kolbeinsey Ridge. In 1999 an eruption of Kolbeinsey Ridge was identified on seismographs by an earthquake swarm 180 km N of Grimsey. Another nearby volcano is located on Tjörnes Fracture Zone, which extends obliquely off the north coast of Iceland towards the island of Grimsey.

Kilauea Volcano, Hawaii
Two lava lakes are present at Kilauea volcano, Hawaii. The east pit lava lake in Pu'u O'o crater occasionally flows across the floor of the south pit. The summit lava lake in Halemaumau crater occasionally overflows the inner ledge. The surface of the lava lake varies from 60m to 150 m deep inside the pit. On the east rift zone an active lava flow is located at the base of the pali in the abandoned Royal Gardens subdivision. The lava contines to advance towards the ocean. Sulphur dioxide emission was high at 1200 tonnes per day on 28th September 2012.

Galeras Volcano, Colombia
On 28th September 2012 an earthquake swarm was recorded at Galeras volcano, Colombia. The earthquakes are possible associated with fluid movement in volcanic conduits, causing fracturing of rock. The earthquakes were located at a depth of less than 8 km at a radius of up to 13 km from the crater. Earthquake magnitudes were less than 1.4 on the richter scale. Ash emissions are occurring on most days. On 28th September, observatory staff on the edge of Galeras reported smell of sulphur.
