On February 22, a 5.7 magnitude earthquake was felt 25 miles (45 km) SSE of Mexicali, Baja California, Mexico. (National Earthquake Information Center).

On February 21, a 5.2 magnitude earthquake was felt 80 miles (130 km) E of San Juan, Argentina. (National Earthquake Information Center).

A river of molten rock poured from the Nyiragongo volcano in the Democratic Republic of the Congo on January 18, 2002, a day after it erupted, killing dozens, swallowing buildings and forcing hundreds of thousands to flee the town of Goma. The lava flow continued into Lake Kivu. (NASA Earth Observatory). (Great aerial photographs of natural hazards at this site!).

On February 17, a 5.4 magnitude earthquake was felt 80 miles (130 km) SE of Bushehr, Iran. (National Earthquake Information Center).

On February 17, a 2.9 magnitude earthquake was felt 25 miles (40 km) S of Sikeston, Missouri. (National Earthquake Information Center).

On February 7, a 3.4 magnitude earthquake was felt 35 miles (60 km) S of Elko, Nevada. (National Earthquake Information Center).

On February 8, a 5.0 magnitude earthquake was felt 20 miles (35 km) SW of Comitan, Chiapas, Mexico. (National Earthquake Information Center).

During early February, high-frequency earthquakes were recorded at Canlaon at depths of 1-5.5 km. In the previous week, several low-frequency earthquakes were recorded. According to a news report, PHIVOLCS stated that the occurrence of low-frequency earthquakes supports the idea that some fluid migration, possibly magma ascent, is occurring. The Alert Level remained at 1 ("Low-level unrest"), and a 4-km-radius Permanent Danger Zone was in effect. (Smithsonian Institution Global Volcanism Program).

An eruption that began at Chikurachki on 25 January deposited ash in the town of Severo-Kurilsk between 1200 and 1500. On 2 February at 1200 an eruption was observed by a helicopter pilot. An ash column from the eruption rose 300 m above the crater and drifted more than 70 km SE. There are no seismic stations at the volcano, therefore, no Color Concern Code was assigned by KVERT. (Smithsonian Institution Global Volcanism Program).

On February 4, a 3.7 magnitude earthquake was felt 25 miles (40 km) E of Ramona, California. (National Earthquake Information Center).

An eruption occurred at Yasur on 25 January around 1300. A pilot reported that an ash cloud rose ~2 km a.s.l. and slowly drifted S. The ash cloud was not visible on satellite imagery, possibly due to heavy meteorological cloud cover. (Smithsonian Institution Global Volcanism Program).

On January 31, a 4.3 magnitude earthquake was felt 20 miles (30 km) SSW of Craig, Colorado. (National Earthquake Information Center).

On February 2, four large earthquakes were felt near Isparta, Turkey. The largest of these was 6.2 in magnitude. (National Earthquake Information Center).

During 23-29 January there was no new volcanic activity at Nyiragongo. During 23 to around 25 January many earthquakes occurred in the region around the volcano; the largest earthquake was M 4.7. Many of the earthquakes were felt in towns near the volcano, including Goma, ~10 km S of the volcano. Several buildings were destroyed by the seismicity in towns near Nyiragongo, including Gisenyi, Rwanda. By 28 January seismicity had decreased and earthquakes were not large enough to be felt by the population. (Smithsonian Institution Global Volcanism Program).

On 23 January at 2054 a large explosion occurred at Stromboli. The explosion was accompanied by a loud noise that was heard at all of the villages on the island and ashfall that lasted for several minutes. During a visit to the summit area on 24 January, INGV-CT staff found the area SE of the summit craters near Il Pizzo Sopra la Fossa between the Bastimento and La Fossetta was covered with ash and blocks. Most of the fallout was comprised of lithic material up to 60 cm in diameter, with minor amounts of spatter up to 1.7 m long. Fine-grained material covered the crater zone and the volcano's NE flank to the village of Stromboli, ~2 km to the NE. A continuous carpet of fallout material covered the zone of Il Pizzo, a spot where many tourists visit. (Smithsonian Institution Global Volcanism Program).
