List of the current Volcanic eruptions
I am doing a research project on volcanoes and volcanic activity present today. Do you have a list or update of current volcanic eruptions in the world today? Include the date of last eruption and geographic location for each, if possible.

Hydrogeology Fetter (fluid density)
1. A fluid in an aquifer is 6.5 m above a reference datum, the fluid pressure is 1800 N/m2, and the flow velocity is 3.4 3 1025 m/s. The fluid density is 1.01 3 103 kg/m3. (A) What is the total energy per unit mass? (B) What is the total energy per unit weight? Show all work.
Hydrogeology Fetter (fluid pressure)
3. A piezometer is screened 723.4 m above mean sea level. The point-water pressure head in the piezometer is 17.9 m and the water in the aquifer is fresh at a temperature of 20°C. (A)What is the total head in the aquifer at the point where the piezometer is screened? (B) What is the fluid pressure in the aquifer at the point ...continues
Hydrogeology Fetters (pressure head)
5. A piezometer in a saline water aquifer has a point-water pressure head of 18.73 m. If the water has a density of 1022 kg/m3 and is at a field temperature of 18°C, what is the equivalent fresh-water pressure head? Show all work.
