Shield volcano is called that because it looks like a warrior put his shield down. It is a gentle volcano and that’s why in Kilauea National Park on Hawaii, the park rangers will escort people close to the volcano when it erupts.
The most explosive and dangerous type of volcano is the Composite Volcano . These are like Mt. St. Helens in Washington state, and Mt. Fuji in Ja.pan.

Mount Lamington is a 1,680 meter-high volcano located in Papua New Guinea. Until 1951, residents of the surrounding Oro Province thought it was just a wooded mountain top. Late that night, on 18 Jan, smoke and lava oozed from the peak, and 3 days later, there was a huge explosion from the north side.
Situated on the Indonesian island of Java, Papandayan is a crater-filled semi-active volcano. In 1772, one side of the volcano exploded and avalanched into the surrounding 40 villages, destroying them completely. Over 3,000 villagers were killed.
1919 mud flow or “lahar” was the most devastating to date. The red hot “lakes” of magma, which began on that fateful day on May 19, flowed fast into nearby settlements and killed over 5,000 people.
The nearest miss since then was in October 2007, when 30,000 local residents had to be evacuated after the volcano was set on Red Alert. Kelut finally blew two weeks later, dusting villages up to eight miles away with ash.
The 1,500 meter volcano, which is still active, had its most noteworthy destruction in 1792.
When several lava domes collapsed
a tsunami was triggered, killing over 15,000 people.
In August 1883, there were a series of extremely violent gigantic explosions with a force 13,000 times larger than the Hiroshima bombing.
The catastrophic explosion – which could be heard as far away as Perth in Australia, spewed over 21 cubic kilometers of rock, ash and pumice up to 70 miles high.
Officially, over 37,000 people were killed.
a gigantic 4,300 meters, the series of explosions from April-June in 1815 rocked the whole world with after-effects, completely changing the stratosphere and ultimately causing the worst famines in the US and Europe in the 19th Century.
In total, over 71,000 people died as a result of burning, starvation or poison.
Death toll was impressively high at up to 25,000, when Vesuvius had its almighty eruption in AD79, it completely buried the town of Pompeii below, as well as devastating other nearby villages. The eruption column, which was a 20 mile tall spout of magma and rock, surged intermittently over twenty hours.
In 1783, it caused nationwide damage when it spectacularly exploded, killing over 50% of the livestock population in Iceland at the time due to the clouds of F & SO 2 . The resulting famine killed 25% of the population. The after-effects were felt all over the world, with Great Britain dubbing that summer “sand-summer” due to carried-over ash.
In North America, the winter of 1784 was the coldest on record. There was a record amount of snow in New Jersey, the Mississippi froze at New Orleans, and there was ice in the Gulf of Mexico.
