A Nov. 22 chemical plant explosion in Danvers, just north of Boston, did not result in fatalities. The early morning timing of the explosion meant that nearby residents were asleep. The explosion’s rumblings, which hit 0.5 on the Richter scale, were not strong enough to damage foundations. The force of the blast sent most debris upwards, and toward places where no buildings were, such as empty fields and a nearby river. When debris did hit nearby homes, most of it hit the roofs, which the Globe points out are strong.”]
