earthquake

According to research published in the journal Nature Communications, the magnitude 7.8 earthquake that was felt in parts of Turkey and Syria in February this year emitted detectable signals eight months before it struck. Although it is currently not possible to predict the magnitude, time and location of earthquakes in the short term, these results would indicate that some large earthquakes may show a detectable preparation phase. However, the authors admit that, due to the large number of variables, recognising these signals and using them for medium-term earthquake prediction remains a challenge.

At around midnight (local time), a powerful 6.8 magnitude earthquake southwest of Marrakech, one of Morocco's main cities, shook the region, leaving hundreds dead and missing amidst completely devastated buildings and constructions.

Faults can generate the most devastating earthquakes. The East Anatolian fault, where the earthquakes in Turkey and Syria occurred on 6 February, has been rupturing quite frequently - every few decades to hundreds of years. Seismic hazard maps are used to design buildings and infrastructure to withstand strong shaking during an earthquake. Reinforced concrete buildings with earthquake-resistant designs are the most appropriate, but often unaffordable for certain regions.

Early this morning, an earthquake with a magnitude of 7.8 struck southeastern Turkey and northern Syria. The authorities have reported thousands of deaths and extensive material damage. A second earthquake has occurred further north than the previous one.
