An earthquake shook Indonesia’s main island of Java on Monday, killing at least 46 people, damaging dozens of buildings, and sending residents into the capital’s streets for safety.   The U.S. Geological Survey said the magnitude 5.6 quake was centered in the Cianjur region in West Java province at a depth of 10 kilometers (6.2 miles). “There are 46 dead people at the Cianjur regional hospital and around 700 injured people. Many were hurt because they were hit by collapsed buildings,” National Disaster Mitigation Agency chief Suharyanto said.
