Italy
Mount Etna Erupts
Mount Etna, on the Italian island of Sicily, erupted yesterday, forcing tourists to flee the volcano. Beginning overnight, the explosions were heard as far away as Taormina and Catania, which are about 31 and 25 miles (50 km and 40 km) from Mount Etna, respectively. A large section of the southeastern crater collapsed, sending an eruption cloud of high temperature gases, ash, and rock several miles into the sky. The collapse triggered a pyroclastic flow of fast-moving, extremely hot volcanic gas, ash and rock, and a lava fountain was generated from the crater’s explosive activity. This is the volcano’s largest magnitude eruption since 2014. Currently, no evacuation orders have been issued and no one has been injured. All tourists, hikers and trekkers who were on Mount Etna during the eruption have been evacuated safely. Around 12 tour operators work on Etna at any one time, and one company owner said they had 40 people on the volcano when it erupted. Mount Etna is Europe’s largest and most active volcano: the current event is the volcano’s 14th episode since mid-March.

Pakistan
Earthquake Triggers Jailbreak
More than 200 prisoners escaped from Malir Jail in Karachi, a southern city in Pakistan, during an emergency evacuation following a powerful earthquake late Monday night. The tremor prompted prison authorities to move inmates for safety, but the ensuing chaos enabled a mass breakout. According to the National Seismic Monitoring Center, Karachi experienced several mild and shallow earthquakes over the past 24 hours, with magnitudes ranging from 2.6 to 3.4. At least one prisoner was killed during the incident, and three prison officers were injured. Security has been heightened across the city and nearby areas. 78 inmates have been caught so far. Police and military units have launched a citywide search operation to recapture the rest of the escaped inmates and investigate how prison protocols failed during the earthquake.

South Africa
South African Land Rising
The land under South Africa rose an average of 0.2 inches (6 mm) due to drought and water loss between 2012 and 2020, according to a new study. This rise amounts to 0.04 inches (2 mm) annually. Scientists have observed South African land uplift for more than a decade, but until now its cause was attributed to geological forces like mantle plumes. A network of permanent GPS receivers across the country measures land height, which is what originally alerted scientists to the phenomenon. GPS data was used to evaluate land uplift and associated water loss, revealing that uplift patterns are correlated with droughts and seasonal shifts between dry and wet seasons. Less water mass correlates with greater land uplift. As land masses dry out, the Earth’s crust bulges. Water storage models suggest that uplift is not permanent and that land could sink to previously normal levels if water returned to reservoirs. These findings offer a potential new way to track water scarcity in the face of increasing drought.

Q: What Pacific island was the world’s richest country per capita for a brief period in the 1980s?
A: Nauru
Nauru’s economic journey began with the discovery of phosphate at the turn of the 20th century. The island’s phosphate reserves, formed over millennia from seabird guano and marine microorganisms, were among the richest in the world. Phosphate, a key ingredient in fertilizers, became increasingly valuable as the global population grew and agricultural demand soared. Between 1906 and 2000, an estimated 80 million metric tons of phosphate were extracted from Nauru, turning the island into one of the world’s most concentrated sources of wealth per capita. For a brief period in the 1980s, Nauru became the wealthiest nation on Earth, with a GDP per capita that reached $27,000 — equivalent to approximately $88,000 today. However, this prosperity was illusory. By 2000, the phosphate supply was virtually exhausted. The depletion of the phosphate reserves left Nauru with limited options for sustainable economic development.
