March 31, 2002

On March 31, a 7.1 magnitude earthquake was felt 50 miles (80 km) NE of Hua-lien, Taiwan. (National Earthquake Information Center). Read the CNN.com news article.


On March 31, a 3.5 magnitude earthquake was felt 20 miles (35 km) S of Jackson, Wyoming. (National Earthquake Information Center).


March 28, 2002

On March 28, a 6.5 magnitude earthquake was felt 80 miles (125 km) NE of Calama, Chile. (National Earthquake Information Center).


On March 27, a 5.2 magnitude earthquake was felt 150 miles (245 km) S of Sibolga, Sumatera, Indonesia. (National Earthquake Information Center).


March 26, 2002

On March 25, 6.1 and 5.0 magnitude earthquakes was felt 100 miles (160 km) N of KABUL, Afghanistan. (National Earthquake Information Center). Read the CNN.com news article.


On March 24, a 4.2 magnitude earthquake was felt 25 miles (40 km) S of Alamo, Nevada. (National Earthquake Information Center).


March 21, 2002

On March 21, a 5.0 magnitude earthquake was felt 85 miles (135 km) SSW of Rabaul, New Britain, PNG. (National Earthquake Information Center).


During 6-13 March, avalanches of incandescent volcanic material continued to flow 2-3 km down Colima's S, SW, and W flanks. Most activity occurred on the S and W flanks, while activity slightly diminished on the SW flank. Block-lava flows extended 320 m down the SW flank and had an estimated volume of 720,000 m3. Block-lava flows reached a distance of 2 km down the W flank, and sporadic avalanches occurred on the E flank. (Smithsonian Institution Global Volcanism Program).


Based on reports received from the town of Severo-Kurilsk, KVERT reported a continuation through 16 March of volcanism that began at Chikurachki on 25 January. On the 16th during 0700 to late evening ash fell in Podgorny settlement, ~20 km SE of the volcano. On a reconnaissance helicopter flight during 1100-1300, observers saw constant gas emissions and sustained ash explosions that rose 200 m above the volcano and extended more than 100 km SE. (Smithsonian Institution Global Volcanism Program).


According to a news article, INSIVUMEH staff stated that beginning on 11 March volcanic activity increased at Santa Mar╠a's lava-dome complex, Santiaguito. Until at least 14 March, ash was emitted from nearly constant explosions and fractures opened on the volcano. Ash rose 600-900 m above the volcano and fell in the towns of Retalhuleu (25 km SSE of the volcano) and San Marcos, and in areas that border M╚xico. (Smithsonian Institution Global Volcanism Program).


March 16, 2002

On March 14, a 5.9 magnitude earthquake was felt 60 miles (100 km) SE of Atka, Alaska. (National Earthquake Information Center).


On March 12, a 3.0 magnitude earthquake was felt 45 miles (70 km) E of South Yarmouth, Massachusetts. (National Earthquake Information Center).


PHIVOLCS staff dispelled concerns that Parker might erupt after a M 7.5 earthquake (according to the US Geological Survey NEIC) occurred near the volcano on 6 March at 0516. According to news articles, tremor caused a portion of the volcano's crater wall to breach and fall into Lake Maughan atop the volcano. Articles also stated that tons of water that were released from the lake washed away houses and about 33 families were evacuated from river banks below Lake Maughan due to fears that more of the lake would overflow. Government agencies plan to conduct an aerial inspection to assess the lake's water level. (Smithsonian Institution Global Volcanism Program).


Seismic tremor increased at San Crist█bal beginning on the afternoon of 6 March. Strong seismicity occurred in 2- to 3-hour periods that were generally separated by less than 1 hour of less intense activity. Scientists visiting the volcano found that the amount of degassing had increased and that temperatures at the volcano were much higher than they had been for several months. Reportedly, incandescent material in the crater was reflected on the clouds above it. According to INETER, the activity at San Crist█bal was not strong enough to warrant raising the Alert Level. (Smithsonian Institution Global Volcanism Program).


An increase in volcanic and seismic activity at Semeru during 3-10 March led VSI to raise the Alert Level from 1 to 2 (on a scale of 1-4). On 8 March observers saw an emission rise ~400 m above the volcano, and two pyroclastic flows travel S as far as 2.5 km down the Kembar River. During the report period there was an increase in tectonic and volcanic earthquakes in comparison to the previous week. (Smithsonian Institution Global Volcanism Program).


March 8, 2002

Eight people were killed and over 100 injured when an earthquake rattled the southern Philippine island of Mindanao at dawn on Wednesday, March 6th, wrecking houses and plunging cities and towns into darkness. The 7.6 magnitude quake originated from the sea 57.5 miles southwest of Isulan, the provincial capital of Sultan Kudarat province on Mindanao island, 500 miles south of Manila. (Reuters.com).


On March 7, a 4.7 magnitude earthquake was felt 25 miles (45 km) SSE of Quezaltenango, Guatemala. (National Earthquake Information Center).


March 4, 2002

On March 3, a 7.3 magnitude earthquake was felt 40 miles (65 km) SSW of Feyzabad, Afghanistan. Several other large earthquakes were felt in the same region on that day. (National Earthquake Information Center).


On March 3, a 3.8 magnitude earthquake was felt 10 miles (20 km) SW of Valdez, Alaska. (National Earthquake Information Center).


A temporary increase in tremor and very small earthquakes occurred at Cerro Negro during 19 February at 2300 to 20 February at 1100. (Smithsonian Institution Global Volcanism Program).


According to news articles, a team of volcanologists from the UN Office for the Coordination of Humanitarian Affairs and the Goma Volcanological Observatory stated that seismicity dramatically increased at Nyamuragira about 25 February. In a statement released to UN headquarters the team of volcanologists said they expect Nyamuragira to erupt within the next several days or weeks. (Smithsonian Institution Global Volcanism Program).


Volcanic unrest continued at Shiveluch during 15-22 February, with several ash-and-gas explosions occurring and seismicity remaining above background levels. An eruption on 15 February at 1501 produced an ash cloud accompanied by pyroclastic flows that travelled 2.5 km down the SE slope of the dome. (Smithsonian Institution Global Volcanism Program).
