  • PLATE TECTONICS MAP

  • INDONESIA

  • REGIONAL TECTONICS The Indo-Australian and Eurasian plates meet in Indonesia, creating a tectonic setting that generates earthquakes and volcanoes.

  • REGIONAL TECTONICS The Indo-Australian plate is moving northward while being subducted under the Eurasian plate creating a zone marked by a submarine trench that can be traced from the northern tip of Sumatra to the Lesser Islands.

  • ESSENTIAL KNOWLEDGE ON EARTHQUAKES

  • EARTHQUAKESAS PART OF THE PACIFIC RING OF FIRE, INDONESIA EXPERIENCES EARTHQUAKES AS A RESULT OF ONGOING SUBDUCTION OF THE INDO-AUSTRALIA AND EURASIA TECTONIC PLATES

  • LESSONS LEARNED FOR DISASTER RESILIENCEALL EARTHQUAKES PREPAREDNESS MEANS THAT YOU UNDERSTAND THE RISKS ASSOCIATED WITH STRONG GROUND SHAKING AND PLAN IN ADVANCE.

  • LESSONS LEARNED FOR DISASTER RESILIENCEALL EARTHQUAKESPROTECTION OF PEOPLE, BUILDINGS AND INFRA-STRUCTURE WITH MODERN CODES AND STANDARDS IS ESSENTIAL FOR COMMUNITY RESILIENCE.

  • THE EARTHQUAKE/TSUNAMI DISASTER OF DECEMBER 26, 2004A reverse fault ruptured the sea floor for more than 1,000 km, generating a M9.3 earthquake and a tsunami that traveled the Indian Ocean, devastating Indonesia and other rim countries, leaving over 220,000 dead.

  • THE EARTHQUAKEThe M9.3 earthquake was located 260 km (155 miles) from Banda Ache, SUMATRA

  • LOCATION

  • THE TSUNAMI

    A major tsunami that traveled the Indian Ocean was generated in the December 26, 2004 subduction-zone earthquake.

  • SUDDEN CHANGE IN VOLCANIC ACTIVITYAfter the December 26, 2004 M9.3 Banda Ache earthquake and tsunami occurred, volcanic activity increased with some of Indonesias dormant volcanoes becoming active again.

  • LOCATION

  • THE WEST SUMATRA EARTHQUAKE: SEPTEMBER 30, 2009A devastating M7.6 earthquake occurred on Wednesday night, September 30, 2009. It occurred on the same fault system that broke on December 26, 2004, generating the M9.3 earthquake and the devastating Indian Ocean tsunami.

  • THE JAMBI EARTHQUAKE OF OCTOBER 1, 2009A M6.6 earthquake occurred on Thursday morning, October 1, just as the airport was reopening and rescue teams were beginning their work. Fortunately, the epicenter was 230 km (140 miles) southeast of the M7.6 quake.

  • PADANG PARIAMAN: OCTOBER 1, 2009Before the earthquake, Padang Pariaman, closest to the quakes epicenter in the Indian Ocean, was a cluster of villages built on the flanks of surrounding mountains, overlooking rice paddies and a river. A landslide triggered by the quake destroyed the villages and the road that connected them.

  • PADANG: OCTOBER 1, 2009The port city of Padang (population of 900,000) was in chaos on Thursday, October 1, after a powerful M7.6 earthquake struck the island of Sumatra on Wednesday.Fires were burning, sirens blaring, dazed residents wandering in streets covered with rubble, and hundreds trapped beneath collapsed buildings.

  • PADANG: OCTOBER 1, 2009Nearly every building over three stories in Padang suffered damage from the first quake, which was just 50 km (30 miles) away.Padangs three main hospitals collapsed.

  • PADANG: OCTOBER 1, 2009At least 1,300 people were dead, but ...The death toll was expected to rise as search and rescue workers dug into collapsed hospitals, offices, hotels, homes, buried villages, and a school, where an estimated 3,000 people were trapped under the rubble.

  • LESSONS LEARNED FOR DISASTER RESILIENCEALL EARTHQUAKES CAPACITY FOR RECOVERY AND RECONSTRUCTION IS ESSENTIAL FOR COMMUNITY RESILIENCE.

  • PRELIMINARY IMPACTSThe powerful earthquakes devastated 10,581 houses, 88 public facilities, 77 places of worship, 76 school buildings, and 68 government offices in Pariaman alone.

  • NOTE: Indonesias long, slow recovery process from the December 26, 2004 earthquake/tsunami disaster was hindered by these quakes.

  • MANY HELPING HANDS FROM ABROAD, AS IN 2004Helping hands were extended immediately by a number of countries: Malaysia, Singapore, Australia, Saudi Arabia, the UK, the USA, Germany, South Korea, China, Japan, Russia, Qatar, the United Arab Emirates, Denmark, Switzerland, Thailand, Taiwan and Norway.
