The volatility index (VIX) is designed to measure
the volatility that options traders are expecting
the stock market to experience over the subsequent
30 days.
VIX is based on a complex formula that reflects
the assumption that, other things being equal,
options will trade for higher prices when expected
volatility rises.
VIX spiked this week as you can see here

VIX wasn't available in the 9-11 days, because
of that chaos. But I remember that one week
after that tragedy it was less than 50. The present
value of around 60 is very high indeed.
