　　Shortly after noon on March 27，Mount Saint Helens erupted for the first time in 1 23 years．People living north of the mountain heard a loud boom that shook their windows，and airline pilots flying near the volcano soon afterwards described a thick black colunm of ash and steam shooting more than 2，100 meters into the sky．

　　A second eruption shook the mountain on March 28．It，too，sent up a column of black ash high into the sky．By March 29，scientists flying over the mountain saw that a second crater
　　 formed about 9 meters from the first one．Strange blue flames flickered(闪烁)inside the crater and sometimes jumped from one crater to the other．
　　By April the mountain had erupted several more times and the snow on the north slope of the peak was black with ash．Ash carried by the wind had fallen on towns as far as 240 kilometers
　　away from Mount Saint Helens．
　　During the first week of April，Mount Saint Helens gave scientists something new to worry about：harmonic tremors(震动)recorded by scientists showed a big eruption would happen．All during April and into May Mount Saint Helens continued to shudder(震动)and shoot out ash．By.April8, two craters had merged to from a vast hole nearly a half of a kilometer wide and 250 meters deep．
　　Scientists'main worry during this time was the growing bulge of rock and ice on．the north face of the mountain．By May 7 scientists feared the worst．Their warnings led Washington Governor to set up safety zones around the mounmin．The inner"red"zone was open to scientists only．The outer"blue"zone was open only to people who got special permits．But in spite of
　　these warnings，some people got past the road barriers and risked their lives trying to get close to the volcano．
