Nigeria
Errant Drone Strike Kills 85
The Nigerian military mistakenly directed a drone attack on a religious gathering in Kaduna state’s Tudun Biri village. Local officials said the drone strike was intended for “terrorists and bandits,” but instead hit a gathering of Muslim civilians celebrating the birthday of the prophet Mohammed. Emergency management officials confirmed that 85 bodies have been buried, but a search for victims is still ongoing. Air raids by the Nigerian military intended for extremists and rebels in Nigeria’s north have frequently resulted in the mass deaths of civilians. There are increasing calls from non-governmental organizations for greater transparency and better-defined principles for drone use in the fight against insurgents.

Indonesia
Eruption Kills At Least 22
Mount Marapi on Indonesia’s Sumatra island erupted unexpectedly on Sunday, leaving at least 22 dead, 10 missing, and 12 injured. 52 hikers have been evacuated from the mountain, and rescue efforts are ongoing as of Tuesday after they were paused due to safety concerns. Between Sunday and Monday, Marapi erupted 46 times. So far on Tuesday, there have been an additional five eruptions, which continue to slow rescue efforts. Marapi has been active since January, at which time there was an eruption with no casualties. Marapi’s eruptions are difficult to predict because the source is shallow and near its peak, meaning that tremors signaling an eruption do not register on seismic monitors. Mount Marapi is one of more than 120 volcanoes in Indonesia sitting on the “Ring of Fire,” the highly active series of tectonic plate boundaries that surround the Pacific.

Lead Pipes To Be Removed, EPA
The Environmental Protection Agency (EPA) and the Biden Administration have announced a plan for the removal of lead water service lines across the country. In a statement released by the White House, the process to replace all lead pipes will be carried out over the course of a decade. The EPA states all lead pipes will be removed regardless of the levels of lead in tap and drinking water samples. Lead is the most common contaminant reported to the agency. The proposal continues the efforts to bring safe water supplies to the 9.2 million people who live in households with lead pipes and service lines as part of 2021’s Lead Pipe and Paint Action Plan. As detailed in the EPA’s Drinking Water Infrastructure and Needs Assessment, states with the highest number of lead service lines include Florida, Texas, Illinois, Ohio, Pennsylvania, and New York.

Q: What country is home to the world’s largest karst area, a topography formed from the dissolution of soluble carbonate rocks?
A: Australia
Karst is an area of land made up of limestone, a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes, forming caves, underground streams and sinkholes. The world’s largest karst area is the Nullarbor Plain, part of the area of flat, almost treeless, dry country of southern Australia. This vast plateau is the world’s largest single exposure of limestone bedrock and occupies an area of about 77,000 square miles (200,000 square kilometers). Karst landscapes are integrated systems, with the surface, caves, and deep aquifer intrinsically linked. Hidden beneath Nullarbor’s ancient landscape is an immense network of caves, including Koonalda Cave, an important archaeological site. Some of the deep caves contain lakes of clear, salty, blue-green water. Flooded passages lead away from these lakes. Only cave divers can reach these passages, which include the longest underwater cave systems in Australia. Where erosion has worn away the land above ground, the Nullarbor Plain terminates spectacularly at the Great Southern Scarp, possibly the world’s longest cliff line.
