The 1985 quake was commemorated, and a national earthquake drill was held, at 11 a.m. local time, just two hours before the 2017 earthquake.]]> 2018-06-27 17:28:45 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268759618 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268770251 Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. ... When the rocks break, the earthquake occurs.]]> 2018-06-27 18:49:45 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268770251 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268770796 Effects. Earthquakes often cause dramatic changes at Earth's surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mud flows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures ..]]> 2018-06-27 18:52:51 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268770796 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268771216 We can easily explain the cause of unusual animal behavior seconds before humans feel an earthquake. Very few humans notice the smaller P wave that travels the fastest from the earthquake source and arrives before the larger S wave. But many animals with more keen senses are able to feel the P wave seconds before the S wave arrives. As for sensing an impending earthquake days or weeks before it occurs, that's a different story.]]> 2018-06-27 18:59:19 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268771216 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268771358 The ground shaking may also cause landslides, mudslides, and avalanches on steeper hills or mountains, all of which can damage buildings and hurt people. The second main earthquake hazard is ground displacement (ground movement) along a fault. ... The tsunami was triggered by the Good Friday earthquake.]]> 2018-06-27 19:01:44 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268771358 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268771657 Earthquakes can strike any location at any time. But history shows they occur in the same general patterns year after year, principally in three large zones of the earth. The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of the world's largest earthquakes occur. It has earned the nickname "Ring of Fire".]]> 2018-06-27 19:05:00 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268771657 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268772119 Earthquakes are usually caused by slippage on a fault due to built up friction between tectonic plates but can also be caused by volcanic eruptions or man made explosions . ... This is one of five reviews on the human impacts of natural disasters, the others being volcanoes, floods, tsunamis, and cyclones.]]> 2018-06-27 19:09:54 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268772119 368876 https://padlet.com/368876/8z4m8k1j2j15/wish/268772914 International support poured in after a devastating earthquake and its aftershock rocked Nepal in April 2015, killing more than 9,000 people. And while the recovery process is underway, organisations working on the ground say there is still much to be done]]> 2018-06-27 19:16:00 UTC https://padlet.com/368876/8z4m8k1j2j15/wish/268772914
