Paleomagnetic secular variation curve for the past two thousand years. Label dates are mean ages before present (B.P.) or Anno Domini (AD), with gray circles indicating estimated error. Note that the magnetic field changes in declination (horizontal arched lines) and inclination (angled vertical lines) over time.

Lahars pick up material as they travel, which can cause damage to structures in their path. Damage here from Mt. Pinatubo, Philippines.
