2. 3 3 10 Science ▶Reading Comprehension 1 Hawaii Kilauea Volcano Erupts Kilauea volcano on the island of Hawaii erupted again. The volcano spewed a plume of lava 160 feet tall. This was more than twice as high as the earlier eruptions. The eruptions emitted 10,000 tons of poisonous sulfur dioxide gas a day. The 1,100 degree Celsius lava destroyed 78 acres of rain forest and buried 162 acres of parkland. The eruptions also caused more than 150 earthquakes. The ground around the eruptions continued to collapse. The forests near the eruptions were exposed to toxic volcanic fumes. ”We are lucky that we have showers and rain,” said Mardie Lane, an official at the Hawaii Volcano Observatory. “One of the biggest dangers is the spread of sulfur dioxide gas. It’s invisible, noxious and toxic. When our rangers are in the field, they use respirators to filter out the harmful gases.” Luckily, no one was hurt and no house was burned. Kilauea is one of five volcanoes that formed the island of Hawaii. The volcano has erupted periodically since it became active in 1983. It has destroyed 213 homes. ☞ Choose the best answer based on the article.
