Violent eruption and series of major pyroclastic f Another violent eruption occurred at Santiaguito lava-dome complex of Santa Maria volcano in Guatemala on the morning of September 21, 2013. At about 02:30 UTC (08:30 local time), the Caliente dome suddenly produced a series of major pyroclastic flows triggered by collapse of accumulated viscous lava at the southeastern rim and flank of the dome. The flows descended on all sides of the lava dome. The explosions, accompanied by shock waves that could be heard in 20 km radius, produced an ash plume that rose to about 4.5 km altitude or about 2 km height above the crater. Significant (but smaller compared) ash plume rose from the pyroclastic flows. Ash fall occurred in Quetzaltenango, Santa María de Jesús, Zuníl and other areas downwind.
8 Wonderful Engineering Project Ideas For Kids That Will Keep Them Busy We have compiled a list of 8 wonderful engineering projects for kids that you can make them carry out and help them understand engineering basics that we all use in our everyday life. Check them out and let us know what you think of them. 8. Build a robot Volcanoes Help Keep the Earth Cooler The fiery power of a volcano is not something we usually associate with good news. Ash from Iceland’s Eyjafjallajokull volcano, for example, caused a major disruption in air travel across western and northern Europe in April and May 2010. Yet behind all that smoke is a silver lining. New research that's being published in Geophysical Research Letters indicates that we can thank volcanoes for the fact that the Earth has warmed less during the first ten years of the 21st century than climate models suggested it would. The average concentration of carbon dioxide in the atmosphere did rise between 2000 and 2010.

The explosions have sent a plume of smoke rising to about 2500 meters above the crater. The strongest explosion was on the night of September 1 which was followed by series of smaller blasts. Authorities are distributing masks and have given themselves a 60-day period to relocate villagers from areas where ash is damaging crops and polluting water sources.
