Macrocytic RBCs are large so tend to have a higher MCH, while microcytic red cells would have a lower value.. MCH is one of three red blood cell indices (MCHC and MCV are the other two). The measurements are done by machine and can help with diagnosis of medical problems.
Alaska's Bogoslof Volcano. Bogoslof volcano, located in the Aleutian Islands about 98 km (61 mi) northwest of Dutch Harbor/Unalaska, is in an active eruption sequence that began in mid-December 2016 and continues today.
The islands, with their 57 volcanoes, are in the northern part of the Pacific Ring of Fire. The Alaska Marine Highway (a ferry service) passes through the islands. The north side of the trench slopes 3Â°â4Â° and the south side lÂ°â4Â°. This process has created the Aleutian Arc.
