October 25, 2001
On October 25, a 3.3 magnitude earthquake was felt 25 miles (45 km) East of Dover-Foxcroft, Maine. (National Earthquake Information Center).

On October 24, a 5.2 magnitude earthquake was felt 65 miles (105 km) northwest of Road Town, British Virgin Islands. (National Earthquake Information Center).

On the morning of 19 October a small phreatic eruption was observed at Idogahama, a beach on the NW coast of Iwo-jima. The Japan Maritime Self Defense Force observed a grayish white-colored plume rising to 200-300 m above the beach surface for 2-3 minutes starting at about 0725. A similar plume was observed for 10 minutes starting at 0806. Observations during 1602-1715 revealed the crater that formed during the eruption was 10 m long and 2-15 m deep. Water inside the crater was dark colored, contained debris, and gushed approximately every 10 minutes. In addition, a steam plume rose up to 600 m above the surface. (Smithsonian Institution Global Volcanism Program).

On October 19, a 7.5 magnitude earthquake was felt 130 miles (210 km) NE of Baubau, Sulawesi, Indonesia. (National Earthquake Information Center).

On October 9, a 4.6 magnitude earthquake was felt 20 miles (30 km) S of San Andres Tuxtla, Veracruz, Mexico. (National Earthquake Information Center).

Also on October 9, several 4.4 magnitude and greater earthquakes were felt off of the east coast of Kamchatka. (National Earthquake Information Center).

On 5 October at Avachinsky volcano, Kamchatka Peninsula, Russia, an earthquake inside the volcano's edifice was accompanied by a small gas-and-steam explosion with small amounts of ash that rose less than 1 km above the crater. A thin layer of ash covered the SE sector of the volcano's edifice. The same day at 1000 larger gas-and-steam plumes were observed rising above the volcano. Mudflows traveled 50-100 m down Avachinsky's SE slope. KVERT personnel believe the mudflows were caused by intensive activity at a single fumarole on the SE side of the summit. On 5 October the Concern Color Code at Avachinsky was raised from Green to Yellow. (Smithsonian Institution Global Volcanism Program).
