D = dormancy of N. pumilio trees lasting locally from April thru September (AMJJAS); E = Earlywood formation between October and January (ONDJ); L = Latewood formation in February and March (FM).
Earthquake data are compared to the rockfall activity and intra-annual position of 97 scars found in 63 cross-sections of 20 N. pumilio trees. In cases where magnitude (M) information is missing a “?” was placed in the table. In the case of the earthquakes in 1960 and 1961, a clear attribution of rockfall scars to individual shaking events was not possible. Seasonal effects on rockfall processes during the winter season influence the detection of earthquake-rockfall relationships and potentially weaken results (for details see text).
