Mt Spurr Volcano (Alaska)
61.30 N, 152.25 W, summit elevation 3374 m, stratovolcano
Saturday 31st July 2004
Elevated numbers of earthquakes continue to be measured beneath Mt Spurr volcano. The level of seismicity has remained constant at 10-20 earthquakes per day over the past few weeks, which is a significant increase on background levels. Only two eruptions have been recorded at Mt Spurr volcano, in 1953 and 1992. The 1992 eruption was short-lived and explosive, with an ash column to 65,000 feet elevation. The 1953 eruption deposited 6mm of ash in Anchorage. The volcano warning colour code is yellow which means that an eruption is possible in the next few weeks and may occur with little or no additional warning.

Egon Volcano (Indonesia)
8.67 S, 122.45 E, summit elevation 1703 m, stratovolcano
Thursday 8th July 2004
Mt Egon volcano in Indonesia has shown increased signs of activity over the last two days. An earth tremor lasting about one minute, followed by a huge explosion, occurred on Tuesday night. The volcano came to life again last Saturday and Sunday, following an eruption in February of this year. The explosion this time was bigger and longer, around one minute in duration. The noise, and some of the materials discharged by the volcano, reached Maumere to the southwest of Mount Egon. After the recent explosion, hundreds of residents from Egon Gahar and Hale villages, who had previously opted to stay put, finally decided to abandon their homes on Wednesday. The total number of refugees amounted to more than 1,000, and they were given accommodation in several school buildings and the community hall in nearby Natakoli village, as well as the Bola district office.More than five centimeters of sulfuric ash has descended on areas around the volcano. Most trees are covered in ash and local roads, previously full of potholes, have been rendered smooth by the gray carpet.
