A powerful earthquake struck southern Ecuador, resulting in significant casualties across two nations. The quake has claimed the lives of at least 15 people and left over 100 injured.

Istanbul, Turkey's largest city and home to around 16 million people, faces the high probability of a major earthquake in the next 20 years, warns Professor Celal Sengor, one of Turkey’s foremost geoscientists. The city sits close to two key fault lines, the North Anatolian and the East Anatolian, and is one of the most seismically active regions in the world. A magnitude 7.5 earthquake along the North Anatolian fault could lead to the destruction of around 90,000 buildings in the city, with a further 260,000 facing significant damage, making around 4.5 million people homeless, according to city officials. The mayor of Istanbul has launched the city’s “roadmap for disaster preparedness,” which includes greater funds allocation for the city’s disaster preparedness program, new emergency points for citizens, and a rapid scanning system to assess the safety of the city’s buildings.

The United States is one of the most seismically active countries in the world, with several states experiencing frequent earthquakes due to their geological location and proximity to active fault lines. According to the United States Geological Survey (USGS), California, Alaska, and Hawaii are the states that have the highest number of earthquakes annually. These states lie along the Pacific Ring of Fire, a region with intense tectonic activity due to subduction zones where one tectonic plate dives beneath another.

In this interview, Jeffrey Schlegelmilch, Director of the National Center for Disaster Preparedness at Columbia University’s Climate School, discusses risk mitigation, disaster preparedness, and government response to disasters. He talks about the challenges of disaster preparedness and how countries can ensure...

The aftermath of the earthquakes in Turkey and Syria has been devastating, with thousands of people losing their homes and loved ones. While rebuilding efforts have begun, there has been criticism of the slow and inadequate response from authorities. Many survivors are still struggling with trauma and fear, and NGOs are working to provide aid and support. The road to recovery will be long and challenging, but with continued efforts and support, progress can be made.

Scientists have developed a new and more accurate model for earthquake forecasting by looking at how faults behave during previous earthquakes. The Long-Term Fault Memory (LTFM) model, which mimics the partial strain release on a fault and the specific timing of past earthquakes, produces more realistic earthquake probability models. This method can improve earthquake preparedness and be applied to other fault systems.

Hundreds of thousands of people in Turkey and Syria are still in dire need of adequate shelter and sanitation a month after a powerful earthquake hit the region. The United Nations has made an appeal for $1 billion to assist survivors, but funding is only at 10%, hampering efforts to tackle the humanitarian crisis. The disaster killed over 46,000 people in Turkey and around 6,000 in Syria, making it the worst disaster in Turkey's modern history. Recovery and reconstruction costs are estimated to be much higher than the $34.2 billion in direct physical damages, according to the World Bank. Aid groups fear a looming public health crisis with families still packed into overcrowded temporary shelters and infrastructure damaged by the quake.

On February 28, 2001, a magnitude 6.8 earthquake struck 11 miles below the Nisqually Delta, causing significant damage in western Washington. This event marked its 22-year anniversary on February 28, 2023. Although the earthquake was over two decades ago, some people in the area are still not prepared for another potential disaster.

According to an article on MyNorthwest.com, Seattle plans to address over 1,100 buildings at risk of collapse in an earthquake. Additionally, more than 400,000 homes in King County need retrofitting, according to Leif Jackson, an expert on the subject. Jackson emphasizes the importance of retrofitting, stating that although it can be expensive, it will ultimately save homeowners money in the long run by preventing costly damage in the event of a major earthquake.
