XRD pattern of halloysite from Olkhon Island, Lake Baikal, Russia, taken at ambient conditions. The calculated patterns for kaolinite including all reflections and those with k = 3n are also plotted for comparison. Although they are broadened, most halloysite peaks are also identified in the calculated kaolinite pattern with k = 3n. However, those indicated with the arrows 1 and 2 on the 02,11 band do not correspond to kaolinite.

Creep in a rupture in Obruchev fault (Olkhon island) after an explosion: a fragment of record. During a few tens of seconds after the explosion the rupture responded in a series of quick motions toward extension followed by rebound to nearly original state. Seven minutes later another explosion was made on the other side of the rupture and was followed by another series of quick motions of the opposite sense (toward compression) and a smaller amplitude because of the preceding upheavels. Later on, under relaxation, motions remained less active for nearly 2 hours and then activity started to increase.
