October 1, 1997 to October 31, 1997
- October 31, 1997
- The Alaska Volcano Observatory (AVO) reports increased fumarolic activity on Chiginagak Volcano on the Alaska Peninsula (AVO Report). Since October 22, there have been local reports of 'increased
steaming, snow-melt, and sulfur smell' and AVO states that this activity 'may reflect an increased heat flux at the volcano'.
- October 28, 1997
- Northern Peru experienced a mag. 6.5 quake. The shaking caused by the moderately deep quake lastest 40 to 50 seconds but only minor damages were reported (CNN).

- *Seismic activity at Montserrat has increased today (MVO 10/28 report). Since October 22nd a new volcanic dome has rapidly grown and now fills half the volcanic crater (MVO 10/26 report and Volcano World). Further eruptions and pyroclastic flows caused by the collapse of the new lava dome are likely in the near future.

- A mag. 5.7 earthquake occurred in the Philippines. No damage was reported.
- October 24, 1997
- Two weeks of torrential rains, blamed on El Nino, have resulted in severe flooding in South America. Floods in Brazil have left over 20,000 people homeless (CNN).
- *A magnitude 4.9 quake startled people in southern Alabama today (Reuters).
- October 23, 1997
- The continuous series of volcanic explosions that have been occurring on Monserrat since September 22 appear to have stopped (MVO Report).

- *Hot stream eruptions propelled rocks and mud up to 200 m in the air above Ruapehu's crater lake over the weekend. IGNS reports that the crater lake level has dropped and that "there remains a likelihood of enhanced eruptive activity in the next few days to weeks should magma be intruded into the volcano" (Ruapehu Eruption Page with latest news releases). CNN reports a curious snowboarder was almost killed by flying rock from an eruption. (Also see CNN Quicktime movie of eruption)
- *Activity at Montserrat continues at an elevated levels with 2 to 3 explosive eruptions a day (and a total of 51 eruptions since Sept. 22). These eruptions usually trigger pyroclastic flows in the surrounding valleys (MVO 10/13 Report).
- October 10, 1997
- Three more aftershocks (the greatest with a magnitude of 4.5) shook central Italy causing more damage to buildings weakened by earlier quakes (Washington Post/AP).

(IGNS reports from 10/10 and 10/3.)
