Understanding Earthquakes
Davis, Amanda; Gray, Ron
Science Teacher, v85 n4 p40-47 Apr 2018
December 26, 2004 was one of the deadliest days in modern history, when a 9.3 magnitude earthquake--the third largest ever recorded--struck off the coast of Sumatra in Indonesia (National Centers for Environmental Information 2014). The massive quake lasted at least 10 minutes and devastated the Indian Ocean. The quake displaced an estimated 30 km[superscript 3] of water, unleashing a massive tsunami across the Indian Ocean that killed an estimated 227,898 people, and caused damages of more than $10 billion throughout the region. Within two hours, waves reached across the ocean to Sri Lanka, India, and Thailand. In seven hours, the effects of the massive quake were felt as far away as the east coast of Africa. This article describes a high school Earth science unit that anchors student learning about earthquakes in the powerful context of the Sumatran earthquake of 2004.
