The new lava dome at Mount St. Helens has grown more over the past three months than it did in the six years following the massive explosion of 1980 that sent volcanic ash circling the globe.

The dome is continuing to build, though geologists with the U.S. Geological Survey say its growth has slowed over the last several weeks. An "explosive type of event" that lasted for 18 minutes on Jan. 16 has added to the fascination with which scientists have been monitoring the mountain in southwestern Washington state.

1. So how does "surges" coincide with "slowed over the last several weeks"?

Odd headline.

Interesting goings on, though.

2. Because the rate of growth has been surprising

and then a few weeks ago it started growing slower, but still growing.
