1. Mt. Pinatubo, located in the island of Luzon, at the inter section of the boarders of the Philippines, erupted in 1991 and produced the second largest eruption of the 20th century (after the 1912 eruption of Novarupta) and the largest eruption in living history.

2. Cheng Huang was a chinease philosopher who created the first earliest invention of a siesmoscope in 132 A.D. This instument was a wine jar that was six feet across and it had 8 dragon heads around the jar. Each dragon head contained a ball in it's mouth and when a earthquake was about to occur the ball from one of the dragon's head fell out and dropped into one of the toads mouth. Whatever direction the dragon's head was pointing that realeased the ball into one of the toads mouth is the direction of where the earthquake was going to strike.

 

The siesmoscope reported before and detected from far away that a 400 miles earthquake was happening. A more sophisticated version of this tool is used today to detect earthquakes and is very useful to help people especially to try to prevent these from hurting people so we can evacuate people from the area so everyone is safe.

3. People also use the Richer Scale to test how strong an earthquake is. The scale is rated from 1-10.

By Jian Kuang 6-301

 

4. There are 5 catogories that can tell you how strong a hurricane is. The highest is 5.

Saffir-Simpson Hurricane Scale
Category	Wind speed	Storm surge
	mph (km/h)	ft (m)
5	≥156 (≥250)	>18 (>5.5)
4	131–155 (210–249)	13–18 (4.0–5.5)
3	111–130 (178–209)	9–12 (2.7–3.7)
2	96–110 (154–177)	6–8 (1.8–2.4)
1	74–95 (119–153)	4–5 (1.2–1.5)
Additional classifications
Tropical storm	39–73 (63–117)	0–3 (0–0.9)
Tropical depression	0–38 (0–62)	0 (0)

5. Cyclone/Nargis had killed tens of thundsand of people in Burma. Hundred of thoundsands of people are still without food, water or shelter. 4,100 people are still missing and hundred of thoundsand are affected. It was very powerful.

 

 

 

 

 

6. A tsunami is a powerful wave caused by an underwater earthquake.

 

7.Everyday 1,800 thunderstroms are taking place somewhere around the world.

 

8.“Tsunami" is the Japanese word meaning tidal wave.

 

 

 

9. The 11th September 1930 eruption of Stromboli was a vulcanian eruption. It started at Ashwas vented for about 10 minutes. Two incredibly powerful explosions occurred which shook the whole island. Blocks were hurled and fell out of the sky, smashing through buildings. A tsunami was generated. By 10:40hrs the explosive phase of the eruption was over. By the end, 6 people had died. Four fishermen died at sea when the avalanches of hot scoria caused the sea to become very disturbed. One person was killed in Stromboli village by falling blocks, and the 6th was killed by the tsunami. It is believed that water entered the conduit due to a partial collapse of the conduit. The water flashed into steam a took the easiest "escape route," via the open conduit. As it expanded in the molten magma it generated the two very large explosions.
