 ==== Castle located on an extinct volcano ====
-Trosky Castle is a castle located on an extinct volcano in the Czech Republic. There, a strange volcano with two craters was active 16 million years ago. In the 14th century, a local nobleman ordered two towers erected on its basalt remains, the taller Virgin (57 m) and the lower Baba (47 m). The rocks under the towers were connected by a 15-meter high wall, creating the courtyard of an amazing castle. The fortress towers over the area — it stands on a hill 514 meters above sea level.

 ==== Magma can be farther from the volcano than originally thought====
-Scientists found that about one-third of volcanoes are about 4 kilometers away from magma chambers. In the case of five volcanoes (two in Japan, two in Indonesia and one in Mexico), this distance between the cone and the magma chamber that powers it exceeds even 10 kilometers. This discovery was a big surprise; according to the established view of volcanology, the magma reservoirs are located directly below the volcanoes.
