__OBSERVATIONS FOR MY VOLCANOES __
**Soufriere Hills:**
 * Overview of volcanic activity in 2010 || Soufriere Hills is a very active volcano. On February 11, part of the lava dome collapsed and left a huge collapse scar on the NE flank, and pyroclastic flows traveled NE to an old airport. In April, there were small areas of incandescence visible for a few nights, and rockfall happened irregularly at different places on the lava dome. There wasn't a lot of activity in early September and early November except for several pyroclastic flows on the W side of the lava dome. But on 29th of November, an area of the unstable, overhanging area on the W side of the lava dome collapsed. There were also areas of incandescence seen of the back wall of the February 11th collapse scar on December 2. ||
 * November 5 || On November 5th, the largest pyroclastic flow traveled 1.5km west down Gages Valley, the hazard level remained at 3. ||
 * October 1 || Several pyroclastic flows starting from the west side of the lava dome travelled west through Gages Valley and into Spring Ghaut. The largest pyroclastic flow moved about 2km. The hazard level is still 3. ||
 * September 3-10 || Parts of the cold dome carapace was removed when small to medium sized pyroclastic flows moved across it.This resulted in several regions of the lava dome becoming hotter, shown in a thermal camera. The largest pyrocalstic flow traveled 2.5km down the Gages Valley to the west. The hazard level is 3. ||
 * April 2-9 || Activity from the lava dome was as a low level. Several smalls areas of incandescence were visible for a few nights during that period of time. Rockfalls happened irregularly at different places of the lava dome. On April 2nd, the Farm River and Trants area were affected by lahars created during heavy rainfall. The hazard level remained at 3. ||
 * February 11 || Part of the lava dome collapsed, leaving a large collapse scar on the NE flank. Pyroclastic flows traveled NE, then flowed along pyroclasic surges, before crossing the sea at several places on the east side of Montserrat. Pyroclastic flows also traveled NE to an old airport, and NW to as far as Cork Hill. Ash fall occurred in four different places. According to news reports, flights in and out of those regions were temporarily closed due to ash plumes. ||
 * may 23rd 20011 || the volcano is still erupting. the pyroclastic flow it still going on. the Hazard level is still at 3. ||

**Sakura-Jima:**
 * October 1 || A pilot spotted Sakura-Jima throwing out an ash plume that reached a height of 1.8km. ||
 * September 15-16 || On 15th Septemer, Sakura-Jima erupted on the same day a pilot reported seeing an ash plume at an altitude of 3km above sea level. The next day, a pilot reported an ash plume rise to an altitude of 1.8km and drift southeast. ||
 * April 7-13 || Explosions from the volcano sometimes made plumes identified by satellite images. These plumes and ash plumes-occasionally seen by pilots-rose to altitudes of 1.3 to 1.5km. Sometimes these plumes travelled NW, E, and SE. ||
 * February 3-9 || Several explosions from Sakura-Jima produced ash plumes that rose to altitudes of 1.5-3km, and drifted SE and N. An eruption on February 8 made a 1km high (about) lava fountain, an ash plume with abundant lighting, and incandescent material fell onto the flanks of the volcano. ||
 * may 23 2011 || the volcano is still exploding from Sakura-jima. many pilots said the ash went up 2.1- 2.3km in the air. ||
