The second-largest volcanic eruption of the 20th century, and by far the largest eruption to affect a densely populated area, occurred at Mount Pinatubo in Philippines on June 15, 1991. The eruption produced high-speed massive falling of hot ash and gas, giant mudflows, and a cloud of volcanic ash hundreds of miles across. The impacts of the eruption continue to this day.
A huge cloud of volcanic ash and gas rose above Mount Pinatubo, Philippines, on June 12,1991. Three days later, the volcano exploded in the second-largest volcanic eruption on Earth in this century. Timely forecasts of this eruption by scientists from the Philippine Institute of Volcanology and Seismology and the US Geological Survey enabled people living near the volcano to evacuate to safer distances, saving at least 5000 lives.

For, although a reduction in the existing money-wage would lead to a withdrawal of labor, it does not follow that a fall in the value of the existing money-wage in terms of wage-goods would do so, if it were due to a rise in the price of the latter. In other words, it may be the case that within a certain range the demand of labor is for a minimum money-wage and not for a minimum real wage. The classical school has tacitly assumed that this would involve no significant change in their theory. But this is not so.
