In the past 9 days (http://www.iris.edu/seismon/last30.html), Indonesia has had 69 tremors with seven of them being over 6.0 on the Richter scale.:yikes: If you are planning a trip there, you may want to take paper cups and leave the Waterford at home.
God help those people.:wish:
(The Richter magnitude scale (http://en.wikipedia.org/wiki/Richter_scale), or more correctly local magnitude ML scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a seismometer output. Measurements have no limits and can be either positive or negative. The energy released is also logarithmic, but the base is approximately 32. Thus a two unit increase on the Richter scale corresponds to over 900 times an increase in released energy.)
